...This will be an aggregate of of all test times, not the time it took to run the tests. Not sure which metric we want to track, I can see merit in both.

As an example, suppose we ran 100 tests in 10 processes with each test taking 30 seconds. This metric would report a total test run time of 50 minutes, when in reality, it actually took 5 minutes for the tests to run.
