TestNG is a testing framework focused on providing both unit and functional testing abilities in the Java programming language. It supports parallel testing, data providers, dependencies, groups and other features.

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:

  • Annotation support.
  • 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 multi-thread 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 run-time and logging (no dependencies).
  • Dependent methods for application server testing.
  • Detailed reports of executed tests.
  • Distributed testing: allows distribution of tests on slave machines.

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

I want to run a test case multiple times. Is that configurable in the testng.xml? If I add a loop in the test method, then the results of each run will not be affected in the testng report.
