Can you describe the major features of TestNG?

TestNG is a popular testing framework for Java that provides a wide range of features and capabilities for testing applications. Here are some of the key features of TestNG:

  • TestNG allows for flexible test configuration and supports running multiple instances of the same test class.
  • It supports a powerful execution model and parameterized and dependent method testing.
  • The framework also provides an elegant way of handling parameterized tests using the data-provider concept. It can be extended using different tools and plug-ins like Eclipse, Maven, and IDEA.
  • TestNG uses default JDK functions for runtime and logging with no dependencies. It is designed to cover all types of testing categories, including Unit, Functional, Integration, and End-to-end testing.
  • TestNG also supports different annotations such as @BeforeSuite, @AfterClass, @DataProvider, @Factory, @Listeners, @Parameters, and @Test, which makes it a highly customizable and versatile tool for software testing.
