Testing #117304

"TestRun" is a strange name as a subclass of "TestRunOptions".
May be "TestRunStateOptions"?

Or perhaps make TestRunOptions TestRequestOptions? The options can be passed by other extensions when they want to request tests to be run, the 'TestRun' is the options plus mutation methods that is given to the test provider.
