Test Designer - Run Level Blockers and UI Improvements

Visual updates to the Test Designer main pages to improve the user experience.

Our goal is to provide a better user experience by making the status of test requests more apparent. The visual updates call attention to blockers and will help distinguish the progress of each test request.

Previously, reviewers could block runs from the Rainforest admin which would require OB/CS intervention to facilitate unblocking. Now, you can unblock runs straight from the UI removing the need for OB/CSM intervention.

If a run is blocked, you can simply address the run-level blocker through the Rainforest interface. Additionally, we made visual updates to the status badges as well as updates to the main pages to reflect when requests were submitted, their status, and how many tests were returned.
