There are multiple benefits of using real devices and emulators; however, the selenium mobile app testing strategy is evaluated by the stage and risk of the application. The best option tool for the testing automation is to use the emulator. If the primary goal of the client is to make the app responsive, then use real and virtual testing.

Talking about the emulator, it is less costly than using real device testing. Most organizations prefer to conduct real-world device testing, which is very expensive. The emulators can be used for both the software and hardware. The emulator is used for testing the application behavior, memory allocation, and central processing units. Emulators are beneficial when it is combined with real-world device testing practices.

Best Practices in Automated Mobile Testing Selenium

1. Designing Robust Test Cases

Achieving the robustness of any application requires the collection of techniques like fault detection, defensive programming, quality assurance, security, monitoring, and modular design. To develop the most effective test case, it is required to ensure the software performs with the user & client demands. For designing a robust test case, you have to understand the functionality and purpose of the app. Before developing the test case, it is essential to evaluate the functionality and Purpose of the API that the attached Documentation can best understand.

Reading the API documentation allows you to understand the work that helps ensure the test cases meet the system specifications. The robust cases are also initiated with the test scenarios & edge cases. Once you have determined the functionality and purpose of API, it’s time to go through the specific test scenarios & edge cases. The test scenarios are used for testing the API functionality, whereas the edge cases are known to identify the boundary conditions.

To use the test cases, there are different HTTP methods which are used like PUT, DELETE GET, etc. Through HTTP methods, the messages are sent to the server, which specifies the type of action. Every HTTP method serves a specific purpose, and it’s critical to test the functionality of every method.

On the other hand, it is also critical to test the API response to ensure functionality. A good test case verifies the API returns that cover the right status code, response body, and headers. It is also essential to validate the API input.

Another selenium mobile app testing best practice is to use the POM (Page object model). The POM design patterns help to develop reusable and maintainable code. It separates the test logic from the page object, which makes the code more organized and easy to grasp.

2. Effective Use of Selenium Grid

The Selenium grid is utilized for running multiple tests on the various operating system & browser types. Through Selenium Grid, testing team can minimize the time frame which is required to execute a test suite. For long and large running test suites, it can save hours and minutes. The selenium grid test is used for testing against the different browsers and in the same browser also. Selenium Grid is known as the smart Proxy server which lets the test run parallel to various devices. The cross-browser testing can be easy with the selenium grid, since the single test can be carried out on multiple machines and browsers.

The 2 major Selenium Grid components are hub and Node. Hub is the server that accepts access requests from the Web driver client, which routes the JSON test commands. Hub server pick data from the client side server and execute them online through the multiple parallel nodes. Node is the remote device, which consists of a remote web driver & native OS. Hub sends the request to the Node in JSON command format and integrates them through webDriver.

Selenium Grid is used for performing cross-browser testing at scale by running the tests on different combinations of browser devices. Utilizing parallel testing, you can ensure a consistent experience across the various browser versions & devices in the shortest time. Through Browserstack Cloud Selenium grid, you will get access to 3000+ combinations of real device browsers for comprehensive testing.

For better Selenium mobile app testing, it is necessary to follow the complete isolation of test data and clean or reset the procedures. Automated mobile testing selenium can instantly be done on 3000+ real mobile devices and desktop browsers. It can run hundreds of tests concurrently that will speed up the execution time into 10X.

Selenium Grid can be integrated in minutes by using different types of framework in selenium and languages. The testing application is hosted on the development environments or behind the firewalls with zero setup & configuration. Selenium testing debugs the errors through the video recording, text logs, console & network logs. The selenium mobile app testing runs safely on tamper-proof physical devices.

4. Writing Maintainable Test Scripts

Integrating the right test-driven script is another plus point. Writing the Selenium tests are all about testing software on the multiple data combination and permutations. The Selenium tests should be data-driven & the multiple data points should drive different tests. The data-driven framework allows the tests to be easily maintained.

Cross-browser testing is a critical aspect of testing. Based on the user requirements, tests should run on multiple browsers. Selenium frameworks like TestNG offer annotations like @Parameter & @RunWith, making the testing easier in multiple browsers. When writing maintainable test scripts on Selenium, you must follow below tips:

• To ensure the Page is uploaded, write ‘wait. Until ()’.
• Choose the drop-down option by choosing the index, text, and values.
• To build the tests generically, the user must pass the initialization values from the configuration file at every time.
• To clear all the cookies, use functions like DeleteAllCookies() of the driver.Manager().
• To switch the new pop-up window, first getAllWindowsHandles(), and then you can switch through the driver.switchTo() method.
• Use the Actions() class to handle the desired web element placed in hover.
• Return value>0 is the best way to ensure that a specific element exists.

For the best practices to write maintainable scripts on Selenium, use the proper locators, which are ID, Class, Link text, TagName, Xpath, etc. Whenever it is possible, use the unique classes as the Selenium locators because these are rarely changed. It is recommended to avoid the Xpath navigation if possible.

The maintainable test scripts may not work correctly on certain browsers during the Selenium test automation. For the best practices, zoom the browser level and set it to 100%. To ensure web page consistency, it is asked to maximize the browser window. Once the test URL is loaded, maximize the window to capture the screenshot of the entire Page. It is also recommended to use the code dependency properly to make it maintainable.

5. Advanced Selenium Features for Mobile Testing

The advanced Selenium feature consists of an enhanced Selenium Grid. The traditional version of Selenium Grid was complex to design and was rigid in terms of scaling. Therefore, a new version of the Selenium grid is introduced with Docker support. It enables the developers & the testers to spin the containers rather than setting up the complex virtual machines. Well, it is redesigned in a certain way so that it can allow QAs for grid deployment on Kubernetes for better scaling.

Managing the advanced Selenium Grid is easy and smooth since there is no need to go through the complex setup procedures. Now, the testers can deploy the grade in 3 modes: Standard mode, fully distributed, and Hub/node. Unlike the older version, the advanced version of the grid supports the IPV6 address.

The Selenium IDE is also upgraded to the new version of Selenium grade. Most of the QA engineers who use the Selenium tools are familiar with the popular playback and recording tools. The Selenium IDE was earlier available, but it was deprecated with the introduction of the recent Firefox version. The recent version of Selenium has improved the GUI to give an intuitive user experience. The new Selenium IDE comes bundled with the Selenium IDE runner.

Apart from these, the recent or advanced selenium grid has relative locators in Selenium 4 with enhanced Documentation and extreme support for the Chrome debugging protocol. Advanced Selenium 4 comes with native support, which directly means the QA team can now use the Chrome development properties such as network, profiler, Fetch, etc.

An understanding of development processes and approaches can help the tester in working closely with the development team. The tester also needs skills related to automation to be at ease with the automated testing framework. The tester needs an updated knowledge base about the recent tools and techniques used for automation testing.

The tester should also have command over communication and team coordination to deal with other members of the team and development team. This increases the efficiency of the framework and also ensures the success of the project as a whole.

• Training and development resources

The testing company should make training processes and development resources available to the professionals so that they can upgrade their skills. The development team and the testing team should work together to exchange feedback so that the teams can improve their methodologies.

7. Security and Compliance Challenges

7.1 Security in Automation Scripts

• Ensuring that test scripts do not expose sensitive data

The test scripts written with the help of Selenium testing frameworks should be made with care and consideration so that they are not exposed to sensitive data and lose their integrity. The tester needs to take into account the testing environment factors so that the sensitive data can be separated from the automation scripts.

• Best practices for secure automation testing

The testing team needs to implement the best practices needed for secure automation testing processes. The best practices include planning the test cases way ahead of time and ensuring that they align with the needs of the application. The testing team also needs to have transparent channels of communication with the development team and internally for the test processes to be successful.

7.2 Compliance with Regulations

• Understanding the impact of regulations on testing

The regulations of testing that align with the Selenium environment are in place to ensure that the testing cases produce ethical and maximum output. For the best kind of testing output, the regulations and industry standards need to be followed.

• Strategies to ensure compliance

The strategies to ensure compliance inside the Selenium testing framework include something as simple as naming test cases and test suites properly and organizing the test environment. Steps like maximizing the browser window can also help improve the pace and output of Selenium testing.

Overcome Selenium Automation Hurdles: Take Action Now!

The Selenium Automation challenges can be reduced if you have a skilled and proactive automation testing team in your company. The use of an upgraded Selenium framework and supporting tools can improve the process of test automation and minimize challenges.

A selenium software testing firms might face challenges like using the framework across different browsers and systems. The company might also face limitations like test flakiness, lags in performance and speed. The company needs to invest in upskilling and maintenance of the testing automation framework for better output and long-term use of the Selenium testing framework.

Nevertheless, there are instances when automation scripts tend to run slower. In comparison to Selenium tests, Integration and Unit Testing are generally faster. Occasionally, a single test may take several minutes to execute, and this sluggishness becomes more pronounced when dealing with a larger number of tests.

Nonetheless, there are effective approaches available to accelerate Selenium tests and improve the efficiency of Selenium automation testing. So, let’s understand those approaches one by one.

12 Ways To Execute Selenium Test Faster

There are several ways to execute Selenium tests faster and improve their performance. Here are some techniques you can consider:

1. Parallel Testing In Selenium Automation

A straightforward approach to accelerate Selenium test cases is by executing automated tests concurrently on various combinations of devices, browsers, and operating systems. This enables the entire test suite to be completed in significantly less time, making it a convenient method to increase the testing speed.

To put it simply, when there are ten tests to be performed, distribute each test across multiple devices and execute them concurrently. For example, if each test takes ten seconds to run, the entire test suite can be completed in just ten seconds. In contrast, if the suite was run on a single device, it would have taken approximately 100 seconds to finish.

2. Choosing Relevant Web Locators

In a test scenario, web locators serve as fundamental components. They are utilised to automate interactions with web elements by locating them first and then performing the desired actions. The find_elements or find_element method is typically combined with different web locators. However, it raises the question of which web locators are considered efficient for fast element locating in Selenium.

When it comes to speed, the ID web locator stands out as the fastest among all the available options. By using the ID locator and providing the corresponding string or value, you can retrieve the web element. In cases where multiple elements share the same ID, the getElementByID() method returns the first matching element. This method results in faster retrieval of web elements compared to using the Document Object Model (DOM). However, if a web element lacks an ID attribute, it is recommended to consider using the Name attribute as an alternative option.

In cases where web elements lack both the ID and name attributes, the recommended approach is to utilise the CSS selector web locator. The CSS engine consistently performs well across major browsers and offers optimal performance for Selenium’s CSS selector. It ensures minimal compatibility issues with different browsers and enables faster identification of elements, thereby reducing execution time. This web locator, particularly, proves to be the most suitable choice for older browsers like Internet Explorer.

In comparison to XPath, the CSS selector provides better readability. XPath, on the other hand, can introduce consistency issues when transitioning between browsers and is generally considered the slowest web locator. However, if other reliable web locators are not available, XPath can still be used.

In descending order of the execution speed, here is the list of web locators:

• XPath
• CSS Selector
• Name
• ID

3. Use Fewer Web Locators

Once you have selected the appropriate web locators to optimise Selenium tests, the next step is to minimise their usage. It is crucial to keep the count of locators as low as possible. Each time you utilise the find_elements(By) or find_element(By) methods to locate web elements, it involves accessing the Document Object Model (DOM).

As the number of DOM accesses increases, the execution time of your Selenium script also grows. Therefore, it is deemed a best practice to minimise the usage of web locators in Selenium web testing.

Reducing the usage of web locators not only enhances the execution speed but also improves the readability of your tests. This, in turn, minimises the time required for script maintenance. By adopting this practice, you can create tests that are easier to understand and modify, resulting in streamlined test maintenance processes.

4. Avoid Thread.sleep() At All Costs

Web applications have content that is either dynamic or static in nature. In the case of dynamic content, websites utilise AJAX (Asynchronous JavaScript and XML) to load elements on the page at different intervals. This poses challenges when performing operations on elements that are not yet present in the Document Object Model (DOM). By monitoring the document.readyState status, you can determine the DOM’s state. When the document.readyState is complete, it signifies that all resources on the page have finished loading. At this point, you can proceed with performing operations on the web elements present.

Now to account for the delay in resource loading, various wait methods can be employed in Selenium. However, it is important to avoid using Thread.sleep(). While Thread.sleep() is an easy way to pause the execution of a program, it’s not recommended for use in Selenium tests for a few reasons:

• Performance: sleep() literally pauses the execution of your test for a specified period of time. This means if you tell it to sleep for 5 seconds, it will always sleep for 5 seconds – even if the action you’re waiting for is completed in 1 second. This unnecessary waiting slows down your tests.
• Unpredictability: Web pages can load at different speeds depending on a variety of factors (network speed, server response time, browser efficiency, etc.). A sleep time that works now might not work in the future or on a different machine or in a different network environment.
• Resource Consumption: sleep() holds onto thread resources and can reduce the performance of your system, especially if used often in your code.
• Poor Practice: It’s considered bad practice because it’s a form of “busy waiting,” which means the CPU is kept busy without performing any actual task.

Instead, it’s recommended to use Selenium’s built-in WebDriverWait and ExpectedCondition classes, which provide a way to wait for certain conditions to be met before proceeding with the test. They can wait for elements to become clickable, visible, invisible, present, etc. They provide a more efficient, reliable, and elegant solution than Thread.sleep().

5. Re-use The Existing Browser Instance

Reusing an existing browser instance can indeed make your Selenium tests run faster, and here’s why:

• Startup Time: Launching a new browser instance takes time, especially if your tests are configured to start with a completely fresh browser profile (which means no cookies, no web cache, etc.). By reusing an existing instance, you’re skipping the startup time entirely.
• Keep Session Data: By reusing an existing instance, you’re also reusing any existing session data. For example, if you have a test suite where every test requires the user to be logged in, you could log in once at the start of the suite and then reuse the same browser instance (and, therefore, the same session) for all subsequent tests.
• Resource Usage: Each browser instance uses system resources like CPU and RAM. If your system resources are limited, then reusing a browser instance can help keep resource usage down.

However, it’s important to note that reusing browser instances isn’t always the best solution. There are some potential downsides to consider:

• Isolation:

  If tests aren’t properly isolated from each other, one test could change the state of the browser in a way that affects the next test. This can lead to flaky tests and make debugging more difficult.

• Accumulation Of State:

  The longer a browser instance is used, the more state it will accumulate, including cookies, cached data, and possibly memory leaks. This could cause later tests to behave differently than they would in a fresh browser instance.

It’s always vital to consider these trade-offs when deciding whether to reuse browser instances in your tests. It depends on the specific needs of your test suite and the resources available to you.

6. Use Explicit Waits For Automation Testing With Selenium

In Selenium test scripts, an implicit wait is commonly applied to all web elements. However, for conditions such as element selectability, visibility, or clickability, implicit waits are not suitable. Instead, explicit waits offer the ability to apply conditional waits specifically to the web elements present on the page.

To perform explicit wait operations on web elements, the combination of ExpectedConditions and WebDriverWait class is utilised. Unlike remote Selenium, explicit waits run directly within the code. Once the specified condition is met, the explicit wait exits immediately instead of waiting for the entire time duration. The element is returned as a result of the condition successfully finding the web element.

However, if the specified duration elapses and the web element is not found within the Document Object Model (DOM), a TimeoutException is thrown.

Explicit waits offer improved performance in test scripts, as they allow immediate access to the located WebElement when it is found. In fact, by utilising explicit waits, Selenium automation testing services can be enhanced, as the wait operation does not consume the entire specified duration, and the test can proceed as soon as the element is located.

7. Create Atomic And Autonomous Test Scripts

Regardless of the complexity of the test scenario, it is crucial to break it down into multiple “independent and atomic” test cases. This is considered the fundamental requirement for writing efficient Selenium tests. By dividing complex scenarios into smaller, self-contained test cases, it becomes easier to manage and maintain the test suite effectively.

Test automation frameworks such as TestNG provide support for declaring explicit dependencies between test methods using annotations like dependsOnMethods (for methods) and dependsOnGroups (for groups). However, it is important to use test dependency in Selenium test scripts only when there is a need to share data and state between the test methods.

On the contrary, atomic tests are valuable in detecting failures effectively. Maintaining short and atomic tests also aids in reducing the effort required for test maintenance. By ensuring atomicity in Selenium tests, the dependency between tests is minimized, issues in the test implementation can be isolated more easily, the maintenance effort is reduced, and the speed of Selenium tests is increased.

8. Group Test Scenarios

As the test suite expands with the addition of more files and test methods, the complexity of managing it also increases substantially. To alleviate the challenges related to implementing and maintaining the test suite, a recommended approach is to group the tests based on the functionality under the test. By organising the tests into logical groups, it becomes easier to manage, navigate, and update the test suite effectively.

Basically, by grouping test scenarios, the challenges associated with maintaining test suites are reduced, and it also facilitates shorter execution times, depending on the chosen approach for achieving parallelization.

9. Use Selenium 4 (Instead Of Selenium 3)

Selenium 4 is a highly anticipated release in the world of automation frameworks. This release brings substantial improvements and enhancements to Selenium. Some of the notable advancements include:

1. Enhanced & Improved Selenium Grid
2. Selenium WebDriver W3C Standardization
3. Improved Selenium 4 IDE
4. Announcement of Chrome DevTools
5. Announcement of Relative Locators

These enhancements in Selenium 4 offer valuable features and functionalities that contribute to the faster and more efficient execution of Selenium tests.

10. Use Cloud-Based Selenium Grid For Automation Testing

Executing tests in parallel on a local Selenium Grid has limitations in terms of scalability and reliability. This approach may not be suitable for large-scale web applications that require running multiple test suites simultaneously on numerous combinations of browsers, operating systems, and devices. The local Selenium Grid setup lacks the necessary robustness and scalability required for such extensive parallel test execution.

Leveraging cloud-based Selenium Grid platforms accelerates Selenium tests by enabling parallel test execution in a reliable and scalable environment.

11. Use Data-Driven Testing For Parameterization

In scenarios where you need to run specific test cases across various combinations of browsers and operating systems, or against different input data sets, it is not advisable to hard code the values directly into the test methods. A better practice is to employ parameterization, which allows you to run tests against an extensive data set. By using parameterization techniques, you can dynamically supply the necessary values to the test methods, enabling more flexible and scalable test execution.

Parameterization in Selenium not only enhances test coverage but also contributes to faster execution of Selenium tests. The major automation frameworks such as MSTest, NUnit, JUnit, TestNG, and PyTest provide support for parameterized tests in Selenium across various programming languages like C#, Java, and Python.

Parameterized tests offer the potential to accelerate Selenium tests, especially in situations where the same test needs to be executed on multiple test combinations or inputs. Test automation frameworks like TestNG provide the capability to pass parameters through testng.xml. When used in conjunction with parallelism at the “tests” level, this approach can greatly enhance the performance of Selenium tests, leading to faster and more efficient test execution.

12. Use Headless Browsers (When Necessary)

Headless browsers are web browsers without a graphical user interface. They’re very useful for automation, scraping web pages and running tests because they’re faster than regular browsers. In the context of Selenium tests, headless browsers can help speed up your test execution for several reasons:

• Speed: Since headless browsers don’t have to spend time rendering graphical elements to a screen, they can load and navigate through web pages more quickly than a regular browser.
• Resource Consumption: Headless browsers consume less CPU and RAM because they don’t need to render the graphics or run all of the background processes that a regular web browser does. This is particularly beneficial when running tests on machines with limited resources.
• Background Execution: Headless browsers can run in the background and do not require a display to be present. This makes them ideal for use in environments where a display isn’t available, such as continuous integration servers.
• Simultaneous Execution: You can run multiple instances of headless browsers in parallel, which can significantly speed up your test suite.

Conclusion

Ensuring the speedy execution of Selenium tests is vital for the success of your automation testing company. So, take action now to optimize Selenium test execution speed and enhance your overall testing process! Implement the best practices mentioned above to reduce test times, identify bugs at an early stage, and ultimately deliver higher-quality products to your customers.

As of writing this blog, Selenium 4 was the latest version of the widely-used open-source test automation framework. Selenium WebDriver is one of the key components (or blocks) of the Selenium framework.

In this blog, we deep dive into the Selenium WebDriver architecture, along with touching upon the changes in Selenium WebDriver from Selenium 3 to Selenium 4.

Introduction : Selenium Test Automation Framework

For starters, Selenium is an open-source test automation framework that has been in usage since 2004. Selenium 4 is the current stable version of the Selenium Framework. What makes Selenium different from other test automation frameworks is its support for popular programming languages:

• Python
• Java
• JavaScript
• C#
• PHP
• Ruby

Web automation tests written using the Selenium APIs interact with the WebElements in the DOM. Selenium provides language bindings for all the supported languages using which you can write web automation tests that let you perform web UI testing.

Based on the chosen programming language, you need to download the corresponding language binding from Selenium Official Website. At the time of writing this blog, the stable language binding was 4.10.

As per my experience, Selenium WebDriver can be considered as the Heart of the Selenium automation framework. Some of the other major components (or blocks) of Selenium are below:

• Selenium IDE
• Selenium Server (or Selenium Grid)
• Browser Drivers

Selenium provides browser drivers for ensuring that changes (or enhancements) in the web browser do not impact the Selenium tests. You should download the ‘browser driver’ corresponding to the ‘browser version’ (of the browser under test).

What is Selenium WebDriver?

Selenium WebDriver is the successor of Selenium RC (Remote Control), WebDriver & Selenium RC were merged in Selenium 2. Selenium WebDriver is basically a collection of open-source APIs that offer the necessary capabilities to automate interactions with the underlying WebElements on the document (or web page).

It is an object-oriented tool that provides the communication mechanism between the test suites and the intended web browser. The major advantage of Selenium is that it lets you run tests on a local Selenium Grid as well as cloud-based Selenium Grid infrastructure.

Shown below is the top-level Selenium WebDriver architecture diagram:

Source

Selenium Grid in Selenium framework helps in leveraging parallel web automation testing through which Selenium automation tests can be run simultaneously on different combinations of browsers & platform combinations.

Selenium WebDriver methods such as findElement(), findElements(), getTitle(), getWindowHandle(), etc. are leveraged by QA engineers to locate required WebElements and perform appropriate operations (e.g. click, double click, send text, etc.) on the same.

Since Selenium is a very powerful test automation framework, it is recommended to leverage the benefits of the framework by on-boarding a Selenium testing services agency. This is especially helpful in scenarios where you want to accelerate automation efforts but do not have in-house expertise in Selenium automation testing.

Selenium WebDriver Architecture

Now that we have covered the basics of the Selenium automation framework, let’s look at the Selenium WebDriver Architecture in more detail. Until Selenium 3, the JSON Wire protocol was used for communicating between the Selenium client libraries and the corresponding browser drivers.

Selenium 3 WebDriver Architecture

All the major browsers like Chrome, Firefox, Edge, etc. are W3C compliant. Hence, the involvement of the JSON Wire protocol in Selenium 3 means that there is encoding of requests (at the sender’s end) and decoding of requests (at the receiver’s end). This might lead to test flakiness and reduced stability of the automation tests. However, JSON Wire Protocol is replaced with W3C protocol in Selenium 4.

In Selenium 4, the JSON Wire protocol is replaced with the W3C WebDriver protocol. Hence, there is no encoding and decoding of test requests. As a tester, you can expect improved test stability and reduced flakiness with web automation tests implemented using the Selenium 4 framework.

Selenium 4 also has a bunch of other powerful features like relative locators, CDP (Chrome DevTools Protocol) support, improved window handling, super-useful Selenium IDE, and newly architectured Selenium Grid.

Selenium 4 WebDriver Architecture

An experienced testing services company in UK, US, etc. that has executed Selenium projects at scale can help in choosing the best cloud infrastructure to make the most of the Selenium framework.

Conclusion

Selenium is one of the most widely-used test automation frameworks for web automation testing. To leverage the benefits offered by the Selenium automation framework, it is essential to learn the essentials of Selenium WebDriver – the soul of the framework.

In case your team does not have the expertise in implementing and executing Selenium automation tests, it is recommended to partner with an expert Selenium testing services company like KiwiQA. Such a partnership will go a long way to leverage the benefits of Selenium for releasing a top-notch quality product in the market.

Though test automation frameworks like Cypress are picking up pace, Selenium still rules the charts in the ‘web automation framework’ category. Though the JavaScript-based Cypress framework is being preferred for testing modern-age websites (and applications); Selenium – the other open-source framework is still the favorite of testers & QA engineers.

For starters, Selenium is a popular open-source test automation framework that supports 6 major programming languages (Java, Python, JavaScript, C#, Ruby, and PHP).

Support for relative locators, improved Selenium IDE, optimized Selenium Grid, and support for CDP (Chrome DevTools) are some of the major features of the Selenium 4 framework. However, to make the best use of the Selenium automation framework, it is recommended to partner with an experienced Selenium automation testing services company so that your team can make use of the best practices of Selenium automation.

Best Practices To Consider For Selenium Web Automation Testing

Irrespective of the programming language being used for the implementation of test scenarios, it is essential to develop tests in a scalable manner. SDETs and QA engineers should develop tests in such a way that changes in the UI (or WebElements) have minimal (to no) impact on the test case implementation.

Here are some of the best practices that can be considered when using Selenium automation testing:

1. Choose best-suited Web Locators

Selenium test automation is used for automating interactions (or actions) that can be applied on the WebElements in the DOM (Document Object Model). For doing so, Selenium WebDriver provides different methods (or APIs) for locating elements on the document (or page).

XPath, Name, ClassName, ID, etc. are some of the popular web locators that let you locate the desired WebElement on the page. XPath is the slowest but most widely used web locator since it is relatively easy to locate the XPath (relative as well as static).

However, it is important to choose the web locator that meets your requirements. More the time it takes to locate the WebElement, the slower the test execution. Hence, it is important to choose the best-suited web locator to ensure that the test code does not break in case there are any changes in the page design.

2. Leverage Wait Commands in Selenium

One of the major challenges of using Selenium is automating interaction with WebElements located on dynamic web pages. A majority of websites use AJAX to load only those sections of the page that need a reload (or fresh load). Also, there are significant challenges when using the Selenium automation framework for SPAs (Single Page Applications).

Selenium WebDriver APIs would return an error when an attempt is made to interact with a WebElement which is not present in the DOM. This is where wait commands can come handy, as a wait is performed till the required element is present in the DOM.

Implicit Waits, Explicit Waits, and Fluent Waits are the three major types of waits in Selenium. Since Implicit Wait is blocking, hence it is recommended to leverage Explicit Waits as the wait exits as soon as the element is located (or it results in error).

A Selenium automation testing company can help in making the most out of Selenium so that test cases are less flaky and the company can make the best of Selenium automation testing.

3. Use Page Object Model (POM) in Selenium

The challenge with Selenium automation tests is that the tests start becoming flaky and unmaintainable if they are not designed & developed with a long-term approach in mind. For example, a minor change in the UI of the page should not lead to changes in the entire implementation of the test scenario.

Maintainability, reliability, and re-usability are some of the major factors that should be taken into consideration when designing Selenium automation tests. This is where Page Object Model (POM) in Selenium can come handy.

POM is a design pattern where every class file contains the locators of the web pages and each web page is considered a separate class. The advantage of POM is that any change in the website’s UI will only result in changes in the files that house the web locators.

The loose coupling between the locators and test logic makes the Selenium test more maintainable, reliable, and reusable. Leveraging POM is one of the best practices of Selenium automation testing.

4. Write Atomic Test Cases

This is one of the basic but most important things that must be considered on a priority basis. In a large project, your team will have to automate a number of tests aligning to the various functionalities implemented in the product.

The first thing to do is to prioritize the tests so that the most important tests are implemented and executed on priority. It is a bad practice to have interdependence between different tests of the Selenium test suite.

When designing and implementing a Selenium test case, always consider the atomicity of the test cases. Atomic tests ensure that any issue in one test case does not have any impact on the other tests that are a part of the same test suite.

5. Perform Scalable and Reliable Cross Browser Testing

The Selenium framework is designed in such a way that the test case does not interact directly with the web browser. Interactions with the web browser are done via the corresponding browser driver. Though local Selenium Grid can be used to perform testing against different versions of browsers and operating systems; it is not a scalable and reliable approach.

It is recommended to perform cross browser testing using Selenium on a cloud-based Selenium Grid since it results in a massive reduction in the infrastructure expenses.

At the same time, cloud-based Selenium automation testing helps in improving the cross browser coverage since tests can be run parallely across a large number of browsers and device (or platform) combinations.

6. Use Selenium 4 (when necessary)

The latest version of Selenium (i.e. Selenium 4) was released in October 2021. Since it is relatively new in the market, its capabilities and features must be leveraged on a need basis.

Selenium 4’s features like relative web locators are instrumental in reducing the time involved in locating the elements on a page. Locators like toLeftOf, toRightOf, near, etc. can be leveraged to locate WebElements in reference to the other elements on the page.

At the same time, the Selenium Grid in Selenium 4 supports different operating modes like standalone, hub & node, distributed mode, and more.

Since Selenium WebDriver in Selenium 4 is W3C compliant, you can expect less flakiness, better execution speed, and improved stability with tests executed on Selenium 4.

Conclusion

Selenium is one of the most preferred frameworks when it comes to web automation testing. To make the most of the framework, it is important to use the best practices of Selenium automation testing.

Apart from leveraging the best practices of Selenium, it is recommended to partner with a Selenium testing services company like KiwiQA that has expertise in providing Selenium testing services to a range of global clients.

The overall result is an expedited time to market – a metric which is so important in today’s competitive business environment.

When it comes to the testing of software products, the testing strategy should be built in a manner that both manual and automation testing are leveraged to their maximum benefits. For starters, automation testing is a testing technique where specialized automation tools (and frameworks) are used for executing product testing at scale.

Choosing the right automation framework that suits the project needs and requirements is the first step in crafting an effective test automation strategy. Though there are several automation test frameworks, the Selenium framework leads the race. Apart from being proven and open-source, Selenium offers numerous benefits that are not offered by other proprietary as well as open-source frameworks.

In this blog, we have a close look at the why’s of Selenium for web automation testing.

What is Selenium Automation Framework?

Selenium is open-source test automation framework that is primarily used for web automation testing. The current stable version of Selenium is 3.141.59 whereas the Selenium 4 (which is yet to be released) is in the Beta stage.

Selenium provides APIs (or methods) that let you interact with the underlying WebElements on the page (or the DOM). Apart from being open-source, the other advantage of Selenium is that it supports implementation in major programming languages like Python, C#, Java, JavaScript, PHP, and Ruby.

Since it is open-source, it has an active community where automation engineers and testers can take support from other members of the community. In case your team has doubts regarding the choice of the best-suited test automation framework, it is best to consult a company like KiwiQA that has immense expertise in providing Selenium automation testing services to a large number of global clients.

We would not divulge into the architecture or API documentation of Selenium since that is beyond the scope of this blog. Rather, we would list down the top reasons why enterprises should embrace Selenium framework for web automation testing.

Major Benefits Of Selenium Framework For Web Automation Testing

Though there are umpteen benefits of Selenium, we list down some of the major benefits of the Selenium framework for automation testing of websites (and web applications):

1. Extensive Language Support

Though there are other web automation frameworks like Cypress that are suited for automation testing of modern web applications, the major downside is the support for a selected few programming languages. In fact, Cypress only supports the JavaScript programming language.

On the other hand, the Selenium automation framework provides extensive support for all the widely-used programming languages – Python, C#, Java, JavaScript, Ruby, and PHP. From a QA engineer’s point of view, it is just about getting used to the APIs supported by Selenium before they can take a plunge into web automation testing with Selenium.

2. Open-Source

Selenium is open-source and free to use for testing websites and web applications. It has a very active community on StackOverflow as well as Slack where Selenium developers (and other engineers) can suggest you possible solutions.

Open-source and community support are the major drivers behind the growing adoption of the Selenium framework.

3. Supports major platforms and web browsers

A test suite in Selenium interacts with the web browser using the corresponding browser driver. Selenium is available for major operating systems (or platforms) like Windows, Linux, Mac, and Unix.

It is easy to port a working Selenium test suite from one platform to another, as change is only involved in updating the location of the browser driver. In many scenarios, this step is also not required if the browser driver is present in the system path.

That’s not all; automation testers can leverage Selenium for running cross-browser tests across major web browsers (e.g. Chrome, Edge, Firefox, Opera, Internet Explorer, etc.). All you need to do is download the corresponding browser driver in the machine and program the driver in the code.

4. Supports Cloud Testing

For scalable and reliable web automation testing, you should leverage testing on a cloud-based Selenium Grid. A Grid in Selenium constitutes multiple Node(s) and a single Hub.

For running Selenium tests on different versions of browsers, devices, and operating systems; you should use Selenium testing on the cloud. Here, a remote Selenium WebDriver is used for connecting to the Selenium Grid that is present on the cloud.

Selenium testing on the cloud is used by enterprises when they want to test their web product across a large number of web browsers, operating systems, and devices. It avoids the unnecessary need to invest in an in-house testing infrastructure that is difficult to maintain and scale.

5. Integration with CI/CD tools

Shift-left testing and continuous integration are the practices that are followed by a large number of enterprises to build a culture of testing within the organization. Selenium supports integration with major CI/CD tools like Jenkins, Circle CI, Travis CI, TeamCity, and more.

Integration with CI/CD tools helps in ensuring that every line of code checked into the repository goes through multiple cycles of Selenium automation tests. This helps in unearthing bugs at the right time, thereby ensuring that the best quality product reaches the end customer (or consumers).

6. Cross Browser Testing Across Devices

The Selenium automation framework lets you perform cross-browser tests across different browsers, platforms, as well as devices. The application can be tested on emulators, simulators, as well as real devices to make sure it performs uniformly across devices.

Hence, Selenium helps you achieve optimal browser coverage, optimal platform coverage, and optimal device coverage. The result is a top-quality software product that wins over the customers.

7. Super-Active Community

Selenium is a community-based initiative that has been around for many years. The community works together to improve the quality of the Selenium framework along with the implementation of important features suggested by the community.

This community-driven initiative is the major reason behind the growing adoption of the Selenium framework. Selenium which was introduced in 2004 has come a long way and we would be witnessing the major upgrade in Selenium 4.

Selenium 4 is W3C compliant and comes with a super-powerful IDE that is available across Chrome and Firefox browsers.

8. Support for major test automation frameworks

Selenium automation framework can be used with major software frameworks available with Java, JavaScript, Python, and other programming languages supported by Selenium.

Here is a brief of some of the major test automation frameworks that can be integrated with Selenium:

• Python: PyUnit, PyTest, Robot, Behave, etc.
• Java: TestNG, JUnit, Gauge, Cucumber, etc.
• JavaScipt: Mocha, Protractor, NightWatch, Jasmine, etc.
• C#: NUnit, MSTest, xUnit, SpecFlow
• PHP: PHPUnit, Laravel, Behat, etc.
• Ruby: RSpec, Capybara, etc.

9. Single package with multiple functionalities

As mentioned earlier, the Selenium framework constitutes Selenium IDE, Selenium Grid, Selenium WebDriver, and other integral components. Selenium RC (Remote Control) is no longer a part of the framework.

Hence, the Selenium test suite lets you run automation tests at an unprecedented scale, something that is not possible with other test automation frameworks.

10. Parallel Testing

Selenium can be seamlessly integrated with popular frameworks supported by major programming languages. Hence, it lets you leverage the immense capabilities offered by the test framework.

Most popular frameworks (e.g. TestNG, JUnit, xUnit, MSTest, PyUnit, etc.) support parallel testing. When they are used with Selenium, it helps you run Selenium parallel tests across different browsers and platform combinations.

Conclusion

Selenium is one of the most popular test automation frameworks that provides APIs through which tests can interact with the elements in the DOM. Selenium 4 is the most awaited and powerful version of the automation framework since it is W3C compliant and sports a powerful IDE.

Here we covered some of the major reasons to consider Selenium over other test automation frameworks.

Selenium automation testing company can be super useful in scenarios where your organization does not have in-house resources with expertise on Selenium automation testing.
