If you (here "Joe Doe") have opened a bug report and then the bug is (supposed to be) fixed, you have to test, then `Resolve`it. So developer will set the task to `Review` and assign it "back to you" (Joe Doe in the example).
Then the next steps for you (the one who opened the bug) will be:
- you test if the problem is gone
-- if OK, `Resolve` the task (and we are done here)
-- if still a problem, set to `Unsatisfactory` and assign it back to the developer (Ralf Thorn in the example).
