Listen

The evolution of modern application development standards has given rise to various new strategies, testing technologies, and integrations to improve the efficiency and quality of the test cases at the same time. On the other hand, the application developers can use cross browser testing to analyze the application stability when it is subjected to various changes in the form of device version, operating system, or other parameters. Using modern technologies, the testers can also detect and remove bugs as soon as they appear in the core infrastructure of the application. In the segment of automation testing, Selenium is one of the most popular names that has been present for over 10 years.

With this article, we are going to justify Selenium as the best test suit for executing automated cross-browser testing on modern apps. We will also analyze some of the major parameters that can help the developers improve the efficiency of their Selenium-based automation test cases.

Understanding the Requirements for Automation Testing

Modern apps consist of thousands of different elements that can take several months when tested manually. On the other hand, using automated testing, the developers can utilize predetermined test cases to run thousands of different test instances automatically. While implementing automation testing, app developers can also implement the necessary adjustments to ensure that the test cases are customized according to their requirements. While using automation testing, the system will use various data sets to emulate and replicate human interactions while communicating with the app undergoing the development project.

The proper integration of automation testing can boost modern app development projects in the following ways:

• Automation testing is highly efficient when the app developers integrate it with repetitive test cases like regression testing and unit testing. So, the testers can use this extra time to come up with new features that can be rolled out in a future application update.
• Since automation testing requires minimal human involvement, it is not only more accurate but also more efficient and can run 24 hours around the clock.
• While using automation testing, the application developers can also implement additional tools, frameworks, and plugins that are directed toward improving the quality of the application undergoing the development project.
• Automation testing also contributes towards maintaining the resource and time efficiency of the app development project. For instance, app companies can eliminate the requirements of setting up and maintaining a human testing team for development needs.

How Does Selenium Help in Modern Test Automation

Selenium is a popular open-source umbrella project consisting of different tools for executing automation testing on web apps. All the tools under the Selenium infrastructure have a specific role in the application testing cycle. The core infrastructure of Selenium works on the JavaScript programming language which eases the learning curve for newcomers to this industry. Moreover, the free infrastructure ensures that the app developers can use all its features without worrying about any license charges:

By integrating the tools present under the Selenium test suite, the application testers can utilize the following benefits in the test environment:

• It is possible to initiate codeless automation testing by integrating the Selenium-integrated development environment. This tool analyzes user interactions and creates automated test cases based on these interactions in real time. So, the app developers simply have to use the app like a normal user to create the automation test cases.
• In case the developers prefer to create the test cases, they can also achieve this goal by implementing the Selenium client API. This tool helps to create test cases in any of the popular programming languages like JavaScript, Python, Ruby, and many other options. This tool also simplifies the process of importing the finished automation test cases in the native environment of Selenium for the execution process.
• Now that the app developers have successfully created the automation test cases, they can start the execution process using the Selenium WebDriver. This tool analyzes the test parameters and test capabilities to run them on the target elements of the web. While using the Selenium WebDriver for the execution process, the developers can also run the test instances in the native environment of a browser without any dedicated test engine.
• Finally, Selenium also has a tool intended for improving the efficiency of the test cases. Using the Selenium Grid, the app developers can run multiple test instances at the same time by using parallel test execution. In this process, the test environment acts like a hub that connects with several nodes. In this case, each node represents the elements present in the application. As soon as the test environment receives a test code, it redirects it to the respective element for the execution process.

Reasons to Use Selenium for Cross-Browser Testing

Based on our research and understanding, we have created a list of some of the most important parameters that can justify the importance of integrating Selenium for executing cross-browser testing:

Execution of Cross-Browser Compatibility Testing

While using Selenium for executing cross-browser testing, the testers can run the test cases on multiple modern browsers like Firefox, Chrome, Internet Explorer, Edge, and many others. With this process, the testers can ensure that the app’s functioning is consistent and correct across multiple user environments.

The Open-Source and Free App Architecture

Since Selenium is open-source and free, it is highly compelling for individual developers and small start-up companies who do not have enough revenue to invest in testing software. Moreover, it receives constant updates and is properly maintained to ensure that the free infrastructure does not affect its functionality.

Flexibility of Programming Languages

While using Selenium, the application developers can create cross-browser test cases in multiple programming languages like JavaScript, Python, Ruby, and many others. So, it makes it very easy for the app testers to use their preferred programming language while working with Selenium.

Independence of the Testing Platform

Selenium is a platform-independent test suite as it can run on Linux, Windows, and even on Mac OS. Using this feature, the application developers can unify the test cases irrespective of the operating system that they are currently working on. Moreover, the developers can use the Selenium test suit to perform compatibility testing on multiple operating systems at the same time.

Availability of Robust Testing Capabilities

While using Selenium, the application testers can access a series of robust testing capabilities that consist of filling out forms, interacting with web elements, and even handling popups. So, the developers can create complex test scenarios to thoroughly evaluate the behavior of their web app. These test cases can also evaluate the performance of the application when it is subjected to various unusual parameters or use cases.

Options for Integration with Frameworks and Tools

While using Selenium, app developers can integrate additional frameworks and tools to improve the efficiency and quality of the testing environment. For instance, the developers can integrate cloud platforms like LambdaTest to eliminate the requirement of a physical device lab. These platforms can run the test cases on thousands of real devices through remote servers. It is also possible to integrate automation testing frameworks like JUnit and TestNG. Using these tools, the app developers can organize the test cases with the continuous integration of CI pipelines.

Presence of a Large and Active Community

Selenium has a huge community of tech enthusiasts who are always working to improve the testing experience for newcomers. So, the new automation testers can always refer to this community whenever they are struck with any feature of LambdaTest.
