fake time.sleep() for use in tests
fakesleep is a simple module for tests that use time.sleep(). Sleeping in tests is generally considered bad (as it makes tests run slow). Using sleep with time.time() can lead to spurious failures, as clock precision / interpeter overhead can cause small differences in reported times.
But sometimes, you need sleep().
fakesleep provides a fake implementation of time.sleep() that doesn’t actually sleep. It also guarrantees “correct” results for calls to time.time() and other time functions. Note that datetime functions are not faked.
To install, simply call fakesleep.monkey_patch(). To restore the real versions, call fakesleep.monkey_restore().
