RE: [Nmock-general] Inherited properties and DynamicMock (known bug?)

[John P. <Joh...@de...>]

Hi Thibaut,

This is actually the same problem I ran into that I mentioned in a =
recent list post (the issue is "NMO-44" on the jira.truemesh tracker, =
but doesn't seem to be in the sourceforge tracker).  I've got a fix for =
it that seems to work well, but it hasn't been incorporated into the =
official source yet.

If you're interested, I can send you the patch and you can compile your =
own version for the time being.

John.

Subject: [Nmock-general] Inherited properties and DynamicMock (known =
bug?)

Hi,

I'm getting a NullReferenceException while calling SetupResult for an
inherited property (full testcase below) :
- is it a know issue ?
- which tracker should I use to open an issue for that, if not know =
already ?

I found a quick workaround which is to create a custom class
inheriting from DynamicMock, and override Invoke().


regards

Thibaut
