TestNG
Java test framework built for suite configuration, grouping and data providers.
What it is
TestNG was designed around larger integration and end-to-end suites: test groups, dependencies between tests, parallel execution policies configured in XML, and data providers for parameterisation. It remains the default choice in many Selenium-based Java automation frameworks.
Best for
Where it is strong
- Mature parallel-execution and grouping model, ideal for large Selenium suites.
- Data providers make data-driven testing straightforward.
- Test dependencies and ordering, which JUnit deliberately avoids.
Where it falls short
- XML suite configuration is dated and error-prone.
- Test dependencies encourage ordering coupling that makes suites fragile.
- Community momentum favours JUnit 5 for new projects.
