What are the differences between JUnit and TestNG?

What are the main differences between JUnit and TestNG?

JUnit and TestNG are both testing frameworks for Java, but they have some key differences. JUnit is simpler and more widely used, while TestNG offers more advanced features like parallel test execution and data-driven testing.

Can you explain the advantages of using TestNG over JUnit?

Sure! TestNG supports annotations, allows for flexible test configuration, and provides better reporting features. It also supports dependency testing, which JUnit does not.

Is JUnit suitable for large projects?

Yes, JUnit can be used for large projects, but it may require additional libraries for features like parallel execution. TestNG is often preferred for larger projects due to its built-in support for these features.

Which one is better for beginners?

JUnit is generally considered better for beginners due to its simplicity and extensive documentation. TestNG has a steeper learning curve but offers more features.

Can I use both JUnit and TestNG in the same project?

Yes, you can use both frameworks in the same project, but it may complicate your test management. It's usually better to stick with one.
