Selenium testing comes under the category of automation testing which in turn is one of the most advanced ways to verify the performance of modern applications. This is because, with automated testing practices, the developers can run intensive test cases on multiple web apps at the same time.
So, with the help of these processes, the developers can not only verify the standalone performance of all the web elements but also ensure that they do not affect the functionality of each other. Jest is often considered one of the best possible choices for initiating and executing Selenium testing in a modern environment. This is because it has various unique native features that help the developers to efficiently execute the test cases on any complex web app.
With this article, we are not only going to analyze the current offerings of Jest but also would take a deep look at some of the features that justify Jest as one of the best possible options for Selenium testing.
Understanding the Market of Test Automation
Test automation aims to improve the efficiency of the application testing process by eliminating human involvement in the test case execution process. For this purpose, the system will use automated text files that will consist of all the data sets or parameters and other relevant information that will allow the system to communicate and interact with the app. These interactions will allow the system to imitate a real user’s actions. With this process, the system can analyze the usability, simplicity, and user interactivity of the application. Later, the application developers and testers can go through the elaborate test report to understand whether the application is ready for the open world.
It is also possible to make significant changes in the test file to ensure the final result is suitable according to the application undergoing the development process. Moreover, it is also possible to store and reuse almost 60% of the existing automation test data in future development projects. Despite all these benefits, the developers must be cautious of the steep investment that comes with the transition to test automation. This initial investment will cover the charges for various plugins from our libraries and data sets for the proper execution of automation test cases. So, we suggest that app development companies must have enough revenue resources to justify this transition.
Elaborating on the Core Structure of Selenium
While we are in the context of automation testing, it is almost impossible to complete this discussion without elaborating on Selenium. This is because Selenium has been one of the simplest test suites for initiating and executing automation testing on web apps for over 10 years now. All the tools present under this umbrella project help the developers at different stages of the application development process. Since Selenium is an open-source framework, all the application developers can access its features without any license or upfront payment. The tech community of Selenium is always ready to support the new developers whenever they are stuck with any feature of this project.
However, Selenium is only applicable while the developers are working with web apps. This means that for other applications like native apps, cross-platform apps, or hybrid apps, the application developers will be forced to look for an alternative in the market. Now let us briefly understand the functions of all the tools present under the Selenium suit:
We must begin our discussion with the Selenium WebDriver as it is the most important part of the test suite. With the help of this WebDriver, the developers can not only start with automation test cases but also ensure that they are conducted on the correct web element of the education. The Selenium WebDriver is an upgraded version of the previously present Selenium RC. This is because, with the help of the web driver, the application developers can conduct all the test cases in the native environment of the app without any dedicated test engine.
The application developers can initiate and execute countless automation testing with the help of the Selenium Integrated Development Environment. This is because the Selenium integrated development environment can write the test cases based on user interactions in real-time. For generating the test cases with this tool, the developers simply have to interact with the application like a normal user. Moreover, since the test cases are generated on real user interaction, they’re highly accurate in judging the app’s behavior based on various forms of use case scenarios.
However, in certain cases, the application developers must manually write automation test cases. For such instances, the developers can refer to the Selenium client API. This is because, with this tool, the application developers can frame the test cases in any of their preferred programming languages. Some of the well-known names supported by this tool include Java, Python, Ruby, and many others.
Finally, we must appreciate the role of Selenium Grid in improving the usability and functionality of the test cases. This is because, with the help of the Selenium Grid, the application developers can initiate and execute the automation test cases in a parallel configuration. The benefit of this process is that it allows the execution of multiple test cases on different configurations and machines at the same time.
Brief Understanding of Jest
We can simply define Jest as a popular JavaScript testing framework that helps developers to verify the proper performance of all applications based on this popular language. Many application developers consider Jest as one of the best alternatives to verify the stability of React apps. Jest is also considered one of the best apps for initiating and running Selenium testing on modern web applications. This application is developed on top of Jasmine and is maintained by Meta, formerly known as Facebook. The support from Meta ensures that Jest will continue to receive stable updates that will massively improve its usability over the coming years. The developers can integrate Jest with several projects by using node JS, Angular, React, TypeScript, and many other frameworks.
Reasons to Justify Why Jest is the Top Choice for Selenium Testing
To justify Jest as one of the best possible options for running Selenium testing, we have created a list of some of the most popular features that are offered by this tool. They are as follows:
- The setup and configuration process for Jest is straightforward. So, we can easily say that Jest is one of the most welcoming frameworks for new developers and testers who are starting to make the transition to the world of automation testing. Moreover, Jest comes with a default configuration that works well for almost all forms of testing including Selenium testing. So, it saves a lot of time and effort with the application setup process.
- The built-in test runner of Jest allows the developers to easily run the automation test cases in multiple configurations. For instance, while using the test runner, the developers can execute tests in a parallel configuration to optimize the test execution time. The test runner also helps the application developers easily manage the test cases and maintain an activity log. With the help of this activity log, all the teams in the app development company will have a basic idea about the current status of the app undergoing the development process.
- While using Jest, the developers can introduce snapshot testing during the app development lifecycle. Snapshot testing is the process of capturing a snapshot of the application before implementing any changes in the framework. After this, the developers can make the changes and compare the results with the snapshot. It will help the application developers to find out certain elements in the app that can give rise to critical bugs and errors.
- Jest also allows application developers to integrate tools and platforms for improving the quality of the application testing process. For instance, the developers can integrate cloud digital experience testing platforms like LambdaTest which eliminates the hassle of having physical test labs. This is because, with these platforms, the application developers can run all the test cases on real device cloud through remote servers. LambdaTest can run automation test cases from various popular frameworks like Selenium, Cypress, and Playwright. Moreover, LambdaTest can use parallel test execution to execute the Selenium test cases on more than three thousand modern browsers at the same time. LambdaTest can also verify the proper performance of web apps with local host servers. Lastly, it is very easy for app developers to initiate and execute cross-browser testing on real devices with this platform.
- The test mocking feature of Jest allows the developers to replicate an application’s dependencies on various external APIs. With this form of testing, the application developers can verify the stability of the app when it is released in the open world. The test mocking feature also helps to understand how the application deals with unnecessary traffic and user interaction errors.
- While using Jest, it is also possible for the application developers to perform code coverage testing on the app. Code coverage testing is a process of ensuring that there is enough automation test code to verify the proper performance of every element present on the web app. It is a feature that helps the application developers to verify the stability and integrity of every element present on the web pages.
- Jest has a huge community of tech enthusiasts and tech lovers. This means that while working with this framework, the application developers and testers will have access to multiple sample test cases, documentation, and plugins that will help them to improve their experience while writing or executing the test cases. Moreover, the members of the Jest community are very helpful to the new developers and are always there to assist them. Moreover, it is very easy for application developers to integrate Jest with other Java-based tools and plugins.
The Conclusion
With this article, we’ll try to understand some of the common factors that make Jest one of the best possible options for initiating and running Selenium testing. As automation testers and developers, we all can unanimously agree that automation testing will continue to become one of the most dominating factors in the future app development market. So, all of us need to keep ourselves prepared by updating our knowledge regarding all the new automation testing trends and innovations. The app companies can also play their part in this transition by conducting several awareness campaigns and seminars to spread the required knowledge regarding healthy automation testing practices.
