Issue with Isolate.WhenCalled()

Hi,

I'm writing a test against a section of code where 2 separate calls are made against a data layer class with the static methods Exists and Find. I'm mocking the calls using Isolate.WhenCalled(); what seems to happen is that when I add the Isolate.WhenCalled() for the second method call (Find, in this case), it causes the first Isolate.WhenCalled() (for Exists) to be ignored (so I'm obviously getting errors related to database connectivity).

What I'm wondering is if this is pilot error; intended behavior; a bug; or more specifically, what I can do to work around the problem.

TL;DR: When using Isolate.WhenCalled(), it seems you can only use it once against a static object (in my case a data layer), even if the methods being mocked (such as Find/Exist) are different.

Thanks for the help,

Paul
