Yes, it should abort each test after 100 seconds (or not if it completes earlier). > But, something is wrong: I get lots of quick (ie much less than 100 > seconds) failures like this: > > [junit4] Suite: org.apache.lucene.util.TestRamUsageEstimatorOnWildAnimals > [junit4] ERROR 0.00s J2 | TestRamUsageEstimatorOnWildAnimals (suite) > [junit4] > Throwable #1: java.lang.RuntimeException: Interrupted > while waiting for worker? Weird. I'm not sure what's wrong and I'm not able to tell you right now (vacation...). I will look into this once I come back. The problem of "stopping" a running test is not trivial because there are no easy ways of telling which threads have been started from a test, which threads should outlive the test (as in a threadpool initialized from @BeforeClass but used from within a test -- the pool threads should outlive it)... finally there are cases when a thread just won't make it possible to be killed by an external threads (see test cases in randomizedtesting -- look for zombie tests if you're curious). There are many sneaky scenarios. The timeout on jenkins is also not trivial I think. Uwe was reporting that stopping a build on jenkins leaves forked jvms running in the background. I looked into jenkins source code to see how they're killing those running processes... it's really hairy -- os-dependent and doing scans of /proc... brr... Apparently also not an easy thing to do. I'll upgrade junit4 and randomizedtesting to version 1.4.0 which should fix a few problems related to event passing but I'll have to postpone timeouts until I'm back at work full time.
