Custom Argument Checker - can I add parameters?

Hi Brauks,

Don't be shy, this is actually a good question. You were almost spot on; Your parameter checker method should match the ParameterCheckerEx delegate signature as described here: https://www.typemock.com/Docs/UserGuide/ ... Check.html It is also described how to pass arguments to check against to your custom checker. In your case it would be something like this:

public static bool ArraySizeIs(ParameterCheckerEventArgs args)
{
    MyCollectionType paramToCheck = (MyCollectionType)args.ArgumentValue;

    // this is how we extract the parameter we pass to the checker
    int expectedArraySize = (int)args.ExpectedValue;

    return paramsToCheck.Count == expectedArraySize;
}

And here is how to pass the parameter to the checker in the first place:

using (RecordExpectations recorder = RecorderManager.StartRecording()) 
{ 
   MyDal dal = new MyDal(); 

   dal.Delete(null); 
   recorder.Return(results); 
   recorder.CheckArguments(Check.CustomChecker(new ParameterChecker(ArraySizeIs), 2000)); 
}

Please let me know if this helps.

Thanks,
Doron
