- added code from
/org.eclipse.debug.tests/src/org/eclipse/debug/tests/TestUtil.java to
TestUtils
- added logging about test setup/teardown to the PDETestCase to see
which errors belong to which test
- close "Welcome" page for tests to allow developers see what is going
on in the UI
- process UI events/wait for jobs on teardown to allow pending
operations to proceed before starting new tests - this avoids errors in
the log caused by new plugin wizard tasks trying access already deleted
projects
- ProjectUtils should wait till all jobs triggered on project creation
proceed
- ExportBundleTests should use nio to delete files to see if there are
IO errors
- ExportBundleTests should delete export directory before starting to
avoid old artifacts mess up with the test
- ExportBundleTests prints more debug data now
