TestNG is a test framework created by Cédric Beust that helps to meet a significant number of AQA & Dev testing needs. Specifically, TestNG gives developers the ability to create more flexible and powerful tests. TestNG is widely used together with Selenium.

What does NG mean?

It stands for “Next Generation”. TestNG is similar to JUnit, but it is more productive when it comes to managing the flow of your application. The framework’s architecture helps us make tests more structured and provide better validation points.

Some of the features of TestNG that deserve attention:

  • Powerful and diverse annotations to support test cases;
  • TestNG utilizes more Java and OOP features;
  • Separates compile-time test code and run-time configuration data;
  • Parallel test execution, use of dependencies between tests. For example, load and partial failure testing;
  • Flexibility to execute tests with different data sets, through the TestNG.xml file or through the concept of data-providers;
  • Grouping and prioritization of test cases;
  • Generating HTML reports, installing additional software from various plugins;
  • The flexible API plugin is especially important;
  • Generation of test execution logs.;
  • Easy integration with Eclipse, Maven, Jenkins, etc;
  • If you’re planning to dive into automation testing, TestNG might be your best bet.

It is sometimes difficult for beginners to understand the point at which they need to start.
