    sleep_duration = Duration(seconds=-1)
    start = clock.now()
    assert clock.sleep_for(sleep_duration)

    assert stop - start < A_SMALL_AMOUNT_OF_TIME

Example #2

File: test_clock.py Project: asorbini/rclpy

    sleep_duration = Duration(seconds=0.1)
    start = clock.now()
    assert clock.sleep_for(sleep_duration)
    stop = clock.now()
    assert stop - start >= sleep_duration
