I use ClasspathSuite:

The IDE support for run-all-tests is nice, but I’d still like to know how to do a Suite properly, in my case for automated/CI builds.

Creating a suite using JUnit for worked for me:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses({SystemSpeakerTest.class, StringSplitSpeedTest.class})
public class AllTests {

}

See the JavaDoc at http://kentbeck.github.com/junit/javadoc/latest/org/junit/runners/Suite.html

Note: if using the Eclipse run package and this suite is in the same package with the tests then they’ll get run twice, once for the suite and once for the individual test class.

Duh. That works just fine. I think I’ll stop worrying about making the Suite right. Still curious how to do it the other way tho …

Thanks!

Instead of creating a suite you can use Eclipse to run all tests in a package. Select the package, run as, junit test (shift-alt-x t). After that ctrl-f11 will re-run it.

Or get Kent Becks JUnit Max that will automatically run your tests when files are saved.

Yes … I could plug in ScalaTest and quite possibly I should. Does it have Suites? If, as it looks, the issue is with JUnit, am I likely to have the same issues?

I don’t usually recommend solving a problem by adding more unknowns to the mix … that’s my concern here.

Thanks … it may come down to switching horses. Or metaphors.

Probably not what you want to hear but I’ve found it easiest to use ScalaTest and it’s associated JUnit friendly traits:

This way I can write most stuff using all my favourite JUnit annotations etc but benefit from the slightly better assert syntax etc.
