simulator: test: Grey box stopwatch test

Browse source 
Currently we can act on the controls but we cannot "see" the display
in the test suite. That leads us to a slightly odd form of "grey box"
testing. It's functionally black box testing but some of the asserts
have to reach inside the components instead of looking at the display.
