How does TestNG different from JUnit?

TestNG and JUnit are both widely used testing frameworks in the Java ecosystem, but there are some differences between the two:

Annotations: TestNG provides more annotations than JUnit, which allows testers to define tests more precisely.

Test Configuration: TestNG offers better test configuration capabilities than JUnit, which allows testers to define test suites, dependencies, and test execution order more easily.

Parallel Execution: TestNG supports parallel test execution across different threads, which allows for faster test execution times.

Data-Driven Testing: TestNG supports data-driven testing out of the box, which allows testers to run the same test with multiple sets of data.

Test Reports: TestNG generates HTML test reports, which provides more comprehensive test execution reports than JUnit.

Grouping and Dependency: TestNG offers more flexible test grouping and test dependency management features, which allows testers to manage test suites more efficiently.

Configuration Options: TestNG offers more configuration options than JUnit, which allows testers to customize the test environment more easily.

Overall, TestNG offers more features and flexibility than JUnit, especially when it comes to test configuration, parallel execution, and test reporting. However, both frameworks are suitable for test automation, and the choice between them largely depends on specific testing requirements and preferences.
