func WasHWAccelUsed ¶
func WasHWAccelUsed(ctx context.Context, tconn *chrome.TestConn, initHistogram *metrics.Histogram, histogramName string, successValue int64) (bool, error)
WasHWAccelUsed returns whether HW acceleration is used for certain action. initHistogram is the histogram obtained before the action. successValue is the bucket value of HW acceleration success case. Note that it returns true even if more than one successful count is observed. It is because in some cases, we occassionally observed more than one successful count (crbug.com/985068). To prevent it from reporting false negative result, we relax the condition from successful count == 1 to >= 1, regardless it may introuce some false positive result. TODO(crbug.com/985068#c5): follow up the improvement plan.
