With the ever-increasing number of languages and frameworks, it’s quite easy to get lost and confused in this huge sea of all these frameworks. Popular languages like C# provide us with a lot of frameworks and it’s quite essential to know which particular framework would be best suited for our needs.
Gauge is a free open source test automation framework released by creators of Selenium, ThoughtWorks. Test automation with Gauge framework is used to create readable and maintainable tests with languages of your choice. Users who are looking for integrating continuous testing pipeline into their CI-CD(Continuous Integration and Continuous Delivery) process for supporting faster release cycles. Gauge framework is gaining the popularity as a great test automation framework for performing cross browser testing.
There are different interfaces provided by Java that allows you to modify TestNG behaviour. These interfaces are further known as TestNG Listeners in Selenium WebDriver. TestNG Listeners also allows you to customize the tests logs or report according to your project requirements.
Developed in 2004 by Thoughtworks for internal usage, Selenium is a widely used tool for automated testing of web applications. Initially, Selenium IDE(Integrated Development Environment) was being used by multiple organizations and testers worldwide, benefits of automation testing with Selenium saved a lot of time and effort. The major downside of automation testing with Selenium IDE was that it would only work with Firefox. To resolve the issue, Selenium RC(Remote Control) was used which enabled Selenium to support automated cross browser testing.
Continuous Integration/Continuous Deployment (CI/CD) has become an essential part of modern software development cycles. As a part of continuous integration, the developer should ensure that the Integration should not break the existing code because this could lead to a negative impact on the overall quality of the project. In order to show how the integration process works, we’ll take an example of a well-known continuous integration tool, TeamCity. In this article, we will learn TeamCity concepts and integrate our test suites with TeamCity for test automation by leveraging LambdaTest cloud-based Selenium grid.
LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.
Here are the detailed JUnit testing chapters to help you get started:
You can also check out our JUnit certification if you wish to take your career in Selenium automation testing with JUnit to the next level.
