Welcome to the testng wiki!

TestNG is a unit testing framework for the Java programming language inspired from JUnit and NUnit. The design goal of TestNG is to facilitate all kinds of tests: unit, functional, end-to-end, integration, etc., with more powerful, flexible and easier-to-use functionalities. TestNG's main features include:

• Annotation support.
• Support for parameterized and data-driven testing (with @DataProvider and/or XML configuration).
• Support for multiple instances of the same test class (with @Factory)
• Flexible execution model. TestNG can be run either by Ant via build.xml (with or without a test suite defined), or by an IDE plugin with visual results. There isn't a TestSuite class, while test suites, groups and tests selected to run are defined and configured by XML files.
• Concurrent testing: run tests in arbitrarily big thread pools with various policies available and test whether the code is multithread safe.
• Embeds BeanShell for further flexibility.
• Default JDK functions for runtime and logging (no dependencies).
• Dependent methods for application server testing.
• Distributed testing: allows distribution of tests on slave machines.
