I'm using ScalaTest in Eclipse (Juno) with Scala 2.10, and the RunConfigurations window has the ability to run a test file, a test suite, or a test package. When I right click on a package name in the explorer window, there is an option to run the package (thereby running all the tests in that package). However, when I do that, no tests run and it displays this:

```
WARNING: -p has been deprecated and will be reused for a different (but still very cool) purpose in ScalaTest 2.0. Please change all uses of -p to -R.
Run starting. Expected test count is: 0
DiscoverySuite:
Run completed in 57 milliseconds.
Total number of tests run: 0
Suites: completed 1, aborted 0
Tests: succeeded 0, failed 0, ignored 0, pending 0
All tests passed.

```

So, what else do I need to do so I can run all the tests in the package?
