The Testing Activity Board works just like the Assessment Activity Board. Open it from Testing → Activity Board.
Each card
The control and its unit.
Its criticality, and whether it's a regular test, a retest or an extra test.
How long it's been in this stage (amber, then red).
"Attempted" if someone couldn't test it last time.
Click a card for its panel: teal links to the unit, control and checklist, notes, history, and Test Runner.
Moving tests
Drag cards between columns, or use the moves in the panel. The moves you can make depend on your workflow role. Your testing workflow may include a review stage, depending on the template your tenancy chose.
Finishing a test
Signing a test off in the Test Runner doesn't finish it. You land back on the board with the card picked: drag it to Completed. It lands, turns into a "Moved to Test History" card and slides away. See Complete a test.
