Bug 27889 [JUnit] Launcher; all tests in default package ... empty TF
If you select "All tests in Project, Source Folder or Package" and select the default package the TF will be empty. There is no visual indication that one has selected the default package. It should be similar to the indicator in Package Explorer/View: (default package)
