Can I skip a JUnit test while the test is running?

Suppose I want to manually run from my IDE (Intellij IDEA, or eclipse) 4000 JUnit tests; the first 1000 tests run pretty smoothly (say they take 3 minutes all 1000) but the test 1001 takes alone over 30 minutes. Is there a way I can skip the test 1001 (while it's still running) and to let the test 1002 (and the others) keep going. I do not want to @Ignore the test 1001 and rerun the suite because I already have the answer for tests 1-1000; also I do not want to select tests 1001-4000 because it takes too much time.

I would some kind of button - Skip Current Test - which can be pressed when the test is running.

In case such feature does not exist, an enhancement for it needs to be done by the IDE developers or by JUnit developers?

No, you cannot skip tests if they are already running.

What I suggest you do is use Categories to separate your slow tests from the rest of your tests.

For example:

public interface SlowTests {
}

public class MyTest {

     @Test
     public void test1{
     }

     @Category(SlowTests.class)
     @Test
     public void test1001{
         // this is a slow test
     }
}

Create a test suite for the fast tests.

@RunWith(Categories.class)
@ExcludeCategory(SlowTests.class)
@SuiteClasses(MyTest.class)
public class FastTestSuite {

}

Now execute the FastTestSuite if you don't want to run the slow tests (e.g. test1001). Execute MyTest as normal if you want to run all the tests.
