We use JUnit for our Java Unit and Integration tests in Version 5. Combined with @JMockit2 and @truth (from Google) we perform all kinds of tests on our minecraft, standalone and microservice architecture.

We prefer JUnit over TestNG because of the bigger community, better support and the generally more agile development. JUnit integrates nicely with most software, while TestNG support is a little more limited.

JUnit Alternatives & Comparisons

What are some alternatives to JUnit?
An evolving, open source framework designed for writing and running tests in Microsoft .NET programming languages.It is an aspect of test-driven development , which is part of a larger software design paradigm known as Extreme Programming
It is a testing framework designed to simplify a broad range of testing needs, it covers all categories of tests: unit, functional, end-to-end, integration, etc.Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.
It is a mocking framework that tastes really good. It lets you write beautiful tests with a clean & simple API. It doesn’t give you hangover because the tests are very readable and they produce clean verification errors.
It is an integration and functional testing platform that can be used for Java middleware testing. With the main goal of making integration (and functional) tests as simple to write as unit tests, it brings the tests to the runtime environment, freeing developers from managing the runtime from within the test.
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
