Create a DriveCommand to test instead of calling directly from tests.

If the code here between 292 and 302 throws, you could get two screenshots, one from the call on 289 and another from the one in the catch. Is that intentional?

You're right. Worse, if testResult fails which would happen often enough, it will take two screenshots, one from line 289, then another on catching the toolExit. Let me fix that up.

Oh right, the screenshot should be taken after the drive test failure but before the app is stopped. Created #96973 to reinstate this behavior.
