testing: Synchronization with blocking call

vendredi 8 mai 2015

Suppose I have a class with the following interface:

class IEvent
{
    void SetEvent() = 0;
    void WaitForEvent() = 0;
}

WaitForEvent() is a blocking function which waits until another thread calls SetEvent() function.

I'm writing unit tests for this class and want following scenario:

First thread calls WaitForEvent(). After that second thread calls SetEvent().

How to synchronize this threads that SetEvent() call will always follow WaitForEvent() call?

I don't want to use any sleeps because I want unit tests to run as fast as possible.
