> The {{testExecutionGraphRestartTimeMetric}} fails every time i run it on AppVeyor. It also very rarely failed for me locally.
> The test fails at Line 235 if the RUNNING timestamp is equal to the RESTARTING timestamp, which may happen when combining a fast test with a low resolution clock.
> A simple fix would be to increase the timestamp between RUNNING and RESTARTING by adding a 50ms sleep timeout into the {{TestingRestartStrategy#canRestart()}} method, as this one is called before transitioning to the RESTARTING state.
