So you could stop at a breakpoint, fetch the times, then run your program through a little spin loop to burn some CPU before hitting a second breakpoint. Then get the times again and assert that they are > the first set. You could also set a timer in the test between the first and second stop and assert that the difference in system and user time is less than or equal to the timer difference. A single threaded program can only run on one core at a time, so that should always be true.

I added a test for user time. System time seems really likely to be flaky in the unittest. It'll increase with kernel time. However if I use side-effect free system calls like getpid() to try and increase that counter it seems like that'll move around a lot from different kernels on different machines
