What is TestNG?

TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing (testing a class in isolation of the others) to integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers).

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…
