Andrew, That's great. You are really quick. I was still thinking when your solution came up. I was able to build the project and run tests one by one, though I wasn't able to use the perfect Eclipse plugin for JUnit tests. Probably it could make sense to use just an ordinary junit for testing p-unit itself.
Hi Alexei, Do you mean p-unit tests here? p-unit uses both ordinary junit 4 and p-unit itself to run all tests for p-unit. They're AllTests(JUnit test suite format) and PUnitAllTests(p-unit test suite format) under punit.test\src\tests\api\org\punit\all directory. Files in punit.sample are run one by one, because each file is supposed to demo one functionality. :) It's for demo (not testing). Thanks! <snip>
