Running sunit tests from button on class

[LisaAlmarode]

The ability to run a test on a class by pushing the button has inconsistent requirement to select the class first.
When I first click on the package, no class is selected clicking on a button is unresponsive. I have to select a class first.
After the class ran its tests, though, it appears to be able to run them again after I've selected a different class (and that class is no longer selected).

There is a button next to my abstract TestCase class that doesn't ever work. That shouldn't be there (there are, correctly, no buttons on the methods on that class).

If a method fails, it opens a walkback; there is some funny behavior with radio buttons (saw it yellow once but not red). Seems to me even if you don't resume from the walkback, the button shouldn't be gray since tests were run and in my case most passed.

I think there are three issues here:

• Don't require class selection before running tests with button in browser
• Remove test button next to abstract test cases
• After opening a walkback, ensure test button is correct color based on user's action to proceed or terminate the test.
