Instance Method Details

#assert_async_polls_until(period: 0.01, timeout: 5) ⇒ Object

Polls the async event loop until a condition is met

Parameters:

  • period (Float) —

    the period in seconds

  • timeout (Float) —

    the timeout in seconds. The test will flunk if the condition is not met within that many seconds

Yield Returns:

  • a falsy value if the condition is not met yet (i.e. false or nil), and a truthy value if the condition has been met. This value is returned by #async_poll_until
