copied!<p>I'm not sure what the impediment is with your "test run parallelization", but you might be able to do this with a rule if you're willing to use a custom "ignore" annotation instead of the JUnit one. The reason for that is that JUnit handles @Ignored tests at the Runner level, specifically in the <a href="https://github.com/KentBeck/junit/blob/r4.10/src/main/java/org/junit/runners/BlockJUnit4ClassRunner.java#L62" rel="nofollow"><code>BlockJUnit4ClassRunner.runChild()</code></a> (by default). If you could find a way to use a custom Runner in Ant, you could come up with one to meet your needs pretty easily, but I don't know if that's easily doable in Ant.</p> <p>As I first mentioned, though, you can easily use a different annotation and a rule to choose which methods to run. I made up a quick <a href="https://github.com/zzantozz/testbed/blob/master/stackoverflow/9611070-toggleable-custom-ignore/src/test/java/rds/junit/ToggleableIgnores.java#L1" rel="nofollow">example of such a rule on github</a>, along with <a href="https://github.com/zzantozz/testbed/blob/master/stackoverflow/9611070-toggleable-custom-ignore/src/test/java/rds/junit/TestToggleableIgnores.java#L1" rel="nofollow">a test that uses it</a>. My little example uses a system property for switching, but you can also obviously make it switch on anything you can think of that you can get your hands on here.</p> <p>You can clone and run this example with:</p> <pre><code>git clone git@github.com:zzantozz/testbed tmp cd tmp mvn test -pl stackoverflow/9611070-toggleable-custom-ignore -q mvn test -pl stackoverflow/9611070-toggleable-custom-ignore -q -D junit.invertIgnores </code></pre> <p>The one downside of this approach that I can think of is that your tests won't get properly marked as "ignored" because that's also done by the <a href="https://github.com/KentBeck/junit/blob/r4.10/src/main/java/org/junit/runners/BlockJUnit4ClassRunner.java#L62" rel="nofollow"><code>BlockJUnit4ClassRunner.runChild()</code></a> method, and if you peek at <a href="https://github.com/KentBeck/junit/blob/r4.10/src/main/java/org/junit/runners/ParentRunner.java#L255" rel="nofollow"><code>ParentRunner.runLeaf()</code></a> (which <code>runChild()</code> delegates to), you'll see that the notifier, which is what you need to report ignored tests, isn't passed down far enough to be used by a Rule. Again, it's something you'd need a custom Runner for.</p>
