Frameworks for Unittests for Multithreading in Java [closed]

Question

Which frameworks would you recommend for writing unit tests for multithreading code in Java? Like, for example, when you have a program that is supposed to execute a bunch of threads with several allowed paths of executions and certain excluded paths (like "executable unit 1, 2 and 3 can run in parallel, at least two should be run in parallel, and 4 always has to run after 3").

Answer 1

I suggest reading about JUnit @Rule to use them for concurrency tests.

Answer 2

I recommend ContiPerf2 since it is a very easy to use framework. Although I do not think it will provide the possibility to declare execution pathes or something like that.

Answer 3

You can use parametrized JUnit tests, as described here: http://junit.org/junit/javadoc/4.5/org/junit/runners/Parameterized.html

But you will need to program thread logic yourself, for example by using different thread pools.

You can take a look at pathfinder (http://javapathfinder.sourceforge.net/) if you want to prove that your code is thread safe.
