Awesome, that did get past the exception that I was experiencing. I
guess I was assuming that Rhino would automatically set up 'equal'
constraints if I didn't specify them explicitly -- now I know.
Unfortunetly I'm running into a different exception that is puzzling
me. Once I added the constraints my test code made it all the way down
into the playback of the actual code. Once in there I get this
exception:
System.InvalidOperationException: Previous method
'IRateCalculationService.CalculateSpread(5.62, 1.19);' requires a
return value or an exception to throw.
at Rhino.Mocks.Impl.RecordMockState.AssertPreviousMethodIsClose()
at Rhino.Mocks.Impl.RecordMockState.MethodCall(IInvocation
invocation, MethodInfo method, Object[] args)
at Rhino.Mocks.MockRepository.MethodCall(IInvocation invocation,
Object proxy, MethodInfo method, Object[] args)
at Rhino.Mocks.Impl.RhinoInterceptor.Intercept(IInvocation
invocation)
at Castle.DynamicProxy.AbstractInvocation.Proceed()
This is on the first call to method B in my example. It seems fairly
straight forward, except I am explicitly returning a value from within
my expectation:
Expect.Call(rateCalc.CalculateSpread(0, 0)).Constraints(Is.Equal
(newBillRate), Is.Equal(newMcdRate)).Return(newSpread)
Any ideas?
Thanks,
Dan Lash
