Hi Shai,
I think, I remember the difference: tests.dups returns the whole suite with the same random seed, so every run is 100% identical. Tests.iters allows to configure the random seed, by default they are different, but depend on each other. The internal handling of random seeds are the reason why you cannot use globs (I don’t know why…). It was not easy to understand to me.

Rather, it documents that you can combine the two ! :).

So -Dtests.dups=100 -Dtests.method=testXYZ (no glob) -Dtests.jvms=1 would run 100 repetitions of testXYZ on 1 JVM, only that way I don't need to specify a glob? Why do we have -Dtests.iters then? Why not just stick w/ dups and document that you can restrict the number of JVMs if you want?

While this is great, it'd still be good if tests.iters supported no globbing implicitly. Because it doesn't help to run tests that are concurrent already, on multiple JVMs :). Now more threads compete on CPU resources.

I don't mind adding the glob, but it'd be much nicer and easier if the framework did it. Like, it could just check that the specific test method invocation startsWith tests.method? The reason I'm asking is because when I run a single test method from eclipse and add -Dtests.iters, it doesn't work. And I always forget that you cannot run them like that. You have to run the entire test-class, and add the tests.method filter. But then I forget to remove the filter when I actually want to test the entire class ... or if I do remember that, I need to create several run configurations with names ... This is just a convenience. If JUnit doesn't allow that, I'll live without it. Shai
