Junit multiple threads

Question

I have a test case that provides arguments and executes the main method of a class. What would be the best approach using Junit to have multiple threads concurrenlty execute the main method of class.

Answer 1

Not sure if TestNG is an option for you, but it's pretty straightforward with it:

@Test(invocationCount = 100, threadPoolSize = 10)
public void myTest() { ... }

This will cause the test method to be invoked 100 times from 10 different threads. If this test passes and you run it a lot, you can be fairly confident that the code under test is multithread safe.
