Advanced Java Selenium Techniques: Browser Automation, Headless Testing, and More

Application testing is one of the essential processes executed during the app development lifecycle. While performing the testing process, the primary aim is to ensure that all the application components are working as expected. This is a critical process that helps maintain a positive brand image. In the modern app development market, various advanced testing techniques can help developers conduct this process efficiently and improve the quality of the application that is undergoing the development process. Selenium automation testing is an integral part of the modern application development environment that helps developers to create highly interactive apps quickly. Other best practices can help the developer further to improve the quality of the app development process.

Let us begin our discussion with the basics of Selenium and automation testing. With this article, we will discuss some of the most advanced Java Selenium testing techniques that can help developers to maintain their company’s position in the competitive market. We will also discuss some of the best practices, platforms, and tools that can help the developers in this process.

Understanding Automation Testing

All the factors and practices that we’re going to discuss in this article rely on automation testing practices. So, the application developers need to have a basic idea of this advanced testing process. In simple terms, it is an effort to remove human interaction in the application development process. Instead, the system will use a data file consisting of multiple parameters that will help it to replicate human behavior and interact with the application. Based on these interactions, the system will generate a report showcasing the application’s stability, user interactivity, and usability. The developers can use this report to understand whether the application is ready to be released to the open world. It is also possible to make significant changes to the test code to customize it according to the project requirements.

The developers can also store and reuse vast sections of the test code in future app projects. This is because the Selenium test cases are not only reusable but also very easy to store and maintain. However, automation testing comes with a significant drawback. This is because while conducting test automation, the company has to invest a considerable amount to get started. This expense will cover the charges for integrating various plugins, tools, and libraries that are critical for the proper execution of automated test cases. So, we recommend that app-developing companies have a specific idea about their project and business perspectives to understand whether they’re ready for the transition.

Defining Selenium JavaScript Testing

Selenium is one of the market leaders in the segment of automation testing. This wonderful test suite has been present in this segment for over a decade. Since its initial introduction in 2004, it has gone through four major updates, which massively improved the usability of this test suite. All the tools in the Selenium test suite have a specific role in the application testing process. We will learn more about the specific purpose of these tools in the latter part of this article. Since Selenium is based on an open-source architecture, developers can access all of its features without worrying about any licensing fee. It is an essential feature considering the need for more revenue for individual creators and small startup companies.

Similar to automated testing practices, Selenium also has a crucial shortcoming. This is because the Selenium test suit allows test automation only for web apps. If the app companies are working with other applications like native apps, hybrid apps, and cross-platform apps, they have to look for an alternative in the market. Now let us understand the basic function of all the component tools in this suit:

  • Selenium WebDriver is an essential tool as it helps the developers start the test cases and redirect them to the respective element. The Selenium WebDriver is often considered an upgraded replacement for the remote controller. This is because the web driver can natively interact with all the elements of a web application. With the help of Selenium WebDriver, the developers can also execute the test cases in a native environment of a web browser.
  • Selenium Grid runs different parallel test configurations. The most important advantage of such a configuration is that it helps the developers run multiple test cases on different machines simultaneously. It is an innovative feature for complex applications as it consists of thousands of different elements that are almost impossible to test individually.
  • With the Selenium IDE, the developers can create automation test cases in real time. The developers can watch the test cases generated in front of them. The application developers have to interact with the web application like a normal user. Based on these interactions, the system will generate individual test cases.

Best Practices for Selenium Java Testing

Based on our research, certain practices can help developers to realize the most out of their Selenium Java test cases. So, we have created a list of these practices for the simplicity of the new developers and even the veterans. They are as follows:

  • Browser Automation: While working with Selenium Java, the developers can automate the test cases that require a web browser. These test cases include various forms of user interactions like data entry, clicking on certain elements, and completing the basic tasks on a web application.
  • Headless Testing: This form of testing is effective for developers to test cases without a visible browser window. It is beneficial when the developers are conducting the test cases on a remote server. While using Selenium Java, it is possible to perform headless test cases with the help of headless browsers like headless Chrome and many others.
  • Use of Page Object Model: The page object model is an interactive way of improving the modularity and simplicity of the test files. In this process, the developers must select a common factor within all the application’s web pages. Based on these criteria, the developers can easily arrange all the web pages. The developers can also maintain an activity log for the test cases conducted on these web applications.
  • Use of TestNG Framework: TestNG is a popular framework developers can use with Selenium Java. After integrating this framework, the developers can gain access to multiple additional features like parallel testing, test grouping, and test dependency. With the help of these features, the developers can massively simplify the application development process. To integrate all of these features, the developers simply have to use the TestNG annotations in their test code.
  • Use of Data-Driven Testing: Data-driven testing helps the developers verify the application’s performance against various data sets. With the help of the TestNG framework, the developers can generate random data sets and execute them on the application. It helps the developers verify the application’s stability against various scenarios.

Integrating Platforms and Tools with Selenium Automation Testing

Tools and platforms can massively contribute to reducing the complexity of Selenium automation test cases. There are thousands of such tools that are readily available in the market. However, the developers must choose the correct tool that is suitable according to their requirements. Certain tools can massively contribute towards adding additional features in the app testing process. We can consider the example of cloud platforms that can remove the hassle of having an on-set real device lab in the company. This is because while working with this platform, the developers can achieve similar test results by conducting the test cases on cloud servers.

While using cloud platforms, the developers can also test cases from anywhere in the world. We can gain more knowledge about the influence of cloud platforms in the modern application development process by considering LambdaTest as our benchmark:

Introducing LambdaTest to the new developers is a unified intelligent digital experience testing platform that allows developers and testers to perform manual and automation testing on their mobile and web applications over more than 3000+ browser and OS combinations. With its seamless integration with Selenium, developers can quickly execute their Selenium scripts on a vast selection of real browsers and operating systems in the cloud. Additionally, LambdaTest’s advanced features, like live testing, screenshot testing, and debugging capabilities, make it a potent tool for Selenium testing.

Furthermore, the platform provides a scalable infrastructure that enables parallel testing, automated testing, and integrations with popular CI/CD tools, making Selenium testing more efficient and less time-consuming.

Wrapping Up!

The primary aim of this article was to spread required awareness about the proper use of JavaScript Selenium testing practices. Since we are slowly moving toward the app development market, automation testing practices will ultimately dominate. The app developers and testers must keep themselves equipped with all the required knowledge. It is also essential for the developers to constantly update this information as there are many new additions and changes in this market.

In this regard, app companies can also conduct frequent awareness campaigns and spread the required knowledge in their teams. The developers must remember that proper use of application development practices and technologies will help them to maintain a growing user base in this competitive app development market. Finally, app developers need to choose the correct tools that can complement their application development practices.
