JUnit4 Parallel Runner downloads statistics

A plugin that allows you to run JUnit4 tests in parallel (using multiple CPU cores/threads).

Important: it only works with JDK 7+(because it uses the Fork/Join framework)

Why and when to use it:

• To speed up running every kind of JUnit4 test including unit tests, integration tests and more... • When running multiple test classes, each class is run in a separate thread(no parallelizing is done on method level)

and when running a single test class, every method in it is run in parallel

• It is integrated nicely with the built-in Intellij IDEA runner: works exactly in the same way

(You can select and run a subset of the tests - no need to run all the tests)

• If you have a CPU with at least 4 cores, it will greatly reduce the running time of your tests • Works with every kind of framework including Mockito, Spring etc.

Note: The more tests you have, the better the speedup will be.

Let's say you have 1000 tests which need 40 seconds to run and you have a 6 core CPU,

using this plugin you can reduce the running time of tests by approx. 4x (down to 10 seconds).

Also, no parallelizing is done when running a single method from a single class(the single

method is executed on a single thread)

Warning: Some code is not meant to be run in parallel (sometimes this is the case with integration tests).

Also, if you have tests which are not independent of each other, they might fail.
