24 * Check how long a timeout took to fire.
26 * This method verifies:
27 * - that the timeout did not fire too early (never less than expectedMS)
28 * - that the timeout fired within a reasonable period of the expected
29 * duration. It must fire within the specified tolerance, excluding time
30 * that this process spent waiting to be scheduled.
32 * @param start A TimePoint object set just before the timeout
34 * @param end A TimePoint object set when the timeout fired.
35 * @param expectedMS The timeout duration, in milliseconds
36 * @param tolerance The tolerance, in milliseconds.

46 * Verify that an event took less than a specified amount of time.
48 * This is similar to T_CHECK_TIMEOUT, but does not fail if the event took less
49 * than the allowed time.
