TestNG

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use, such as:

  • Annotations.
  • Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc…).
  • Test that your code is multithread safe.
  • Flexible test configuration.
  • Support for data-driven testing (with @DataProvider).
  • Support for parameters.
  • Powerful execution model (no more TestSuite).
  • Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc…).
  • Embeds BeanShell for further flexibility.
  • Default JDK functions for runtime and logging (no dependencies).
  • Dependent methods for application server testing.

TestNG is designed to cover all categories of tests:  unit, functional, end-to-end, integration, etc…

TestNG requires Java JDK 7 or higher version of java.

Things to note:

  • No need to extend a class or implement an interface.
  • Even though the example above uses the JUnit conventions, our methods can be called any name you like, it’s the annotations that tell TestNG what they are.
  • A test method can belong to one or several groups.
