If you run your entire test suite in dart and everything passes, then all the test icons are green.

If I then run the test suite over again, everything stays green, and then as they are running and passing the briefly flicker, but always stay green. This gives no indication of the progress of the test suite.

It could be great if on the start of the test suite run, all previous success or fail icons were cleared to a grey state, or to a neutral purple or blue 'in progress' or 'pending state, so you can actually see the prrogress of the test run properly represented in the test icons.
