Unit Tests
There are no circular references, this will cause an endless loop.
This workflow is complex because it contains steps that are both parents and siblings to other steps. Steps 5 and 6 has the same parent, step 2. So 5 and 6 are siblings, and step 5 is also the parent of its sibling step 6. Also note: Steps 2 and 3 are siblings, and step 5 is the child of step 2 and also the parent of step 3. So a step can be a parent of its uncle step.
