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 a framework that we implement in our Selenium Automation framework for following advantages.
- Data Driven testing can be achieved.
- Execute the scripts in batch.
- Execute test methods in group wise.
- Generation of HTML reports.
- Integration of TestNG with Maven build tool.
- So powerful because of TestNG annotations.
