Question

I am working on new functionality for a large C# project which is mostly legacy code.
The area that I’m working on handles XML schema messages, creates a schedule for their transmission and places them into some legacy timer code which notifies me when they should be sent.

Although I am new to them, Visual Studio test projects are proving useful in that I can test my code without trying to get the full system up and running (which can take upto 30 minutes on the test hardware!).

I have statically tested my event handling code, but would now like to do so dynamically.
Is this possible? If so how do I go about getting the test project to wait for the event without timing out?

Answer 1

If I understand you correctly, you could use a wait handle to signal the event and have your test project wait for the event handle to be signaled.

void Foo()
{
   var eventSource = ...;
   var waitHandle = new ManualResetEvent(false);
   eventSource.SomeEvent += (sender, e) => waitHandle.Set();

   ...

   // Wait for the event to be fired.
   waitHandle.WaitOne();
}
