// for the outcome of the test.
// Specific tests need (minimally) only to:
// 1- override ExecuteImpl() to implement the test.
// 2- call RecordStopFailure() or RecordFailure() or RecordSuccess()
// at the end of the test.
// 3- Optionally call observer->OnProgress() if the test is long.
// 4- Optionally call observer->OnSkipped() if the test cannot be run.
