    Wait for the watch process in test case

    Because the _watch_process and the failing_process are asynchronous,
    there might be a chance that failing_process exit and _watch_process
    is not executed.

    If the _watch_process is blocked, the method that will be asserted
    will not be called. This will fail the UT, but it is intermittent.
