Unit & ComponentOpen sourceSelf-hostable

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

Java Selenium automation frameworks and large integration suites.

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.
