I’m talking in the Editor window, where you see the list of unit tests. I can walk down that list and uncheck the Active property for the unit tests I don’t want to run at the moment. And when I do that, I’d like to see the icon for that unit test change, so I know it’s inactive.
To make that functionality even more useful, I’d love to see a menu option to set all the unit tests Active again. Make sense? You build your set of tests, know that some code parts aren’t changing anymore, so you make them inactive to stop testing those parts (for speed). But before you roll it all out to system testing, you make them active run them all again.
