Unit Tests
This workflow is complex because it contains steps that are both parents and siblings to other steps. Step 5 and 6 has the same parent, step 2, so 5 and 6 are siblings. But step 5 is also the parent of its sibling step 6. Also note: step 3 is the child of step 1 and the sibling of step 2. And step 5 is the child of step 2 and also the parent of step 3. So a grandchild step can be a parent of it`s uncle step.
