JUnit vs TestNG: Which to Choose?

I'm trying to decide between JUnit and TestNG for my Java project. Which one should I choose?

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

What are the main differences in features between JUnit and TestNG?

JUnit focuses on unit testing and has a straightforward API, while TestNG supports more complex testing scenarios, including integration and end-to-end tests. TestNG also allows for annotations that provide more flexibility.

Can I use both frameworks in the same project?

Yes, you can use both JUnit and TestNG in the same project, but it may complicate your test management. It's usually better to stick with one framework for consistency.

Which framework has better community support?

JUnit has a larger community and more resources available, but TestNG also has a dedicated user base and good documentation.
