Tick Count Backwards Check - busy Confirms that the clock for GetTickCount is a monotonically increasing value that runs backward only when it overflows. This test case reads each subsequent clock tick and verifies that the value is greater than the previous value. If the value is less than the previous value, the difference between the values must be less than twice the resolution of the clock. If the difference between the values is greater than twice the resolution of the clock, this test case fails. By default, this test case runs for 3 hours. You can specify the length of time that it runs by specifying -c "–backwardsRunTime seconds", where seconds is the run time for the test in seconds. The timer for GetTickCount wraps once approximately every 49 days. To test the condition where the timer overflows, set the timer to wrap soon. |
