Walid and Corky looked into coverage testing under scala. It was pretty easy, actually! They were able to set up scct in just a few minutes. When they ran it on Acumen we get the results shown in the figure shown. It is not surprising that the GUI and rendering were not getting any testing. But it's really impressive how well the tests are for the rest of the code. Great job on writing those test cases, Paul Brauner!
