Mocking internal interfaces with Moq

May 9th, 2008

Is a same method you would use with NMock2, but with “DynamicProxyGenAssembly2″ in InternalsVisibleTo.
This strange name is a default dynamic assembly name used by Castle.DynamicProxy.

Do not forget that the attribute should be added to the assembly with internal types, not to the tests assembly (obvious, but I got it wrong the first time).

Update: yesthatmcgurk has pointed me to the fact that for strongly named assemblies you have to specify the public key as well. So the correct attribute for the strongly named assembly should be

[assembly:InternalsVisibleTo("DynamicProxyGenAssembly2,
PublicKey=002400000480000094000000060200000024000052534
1310004000001000100c547cac37abd99c8db225ef2f6c8a3602f3b

// without line-breaks

    Actually the public key makes it _not_ work for me. Same thing happens here: http://groups.google.com/group/moqdisc/browse_t…

    Just using it without the public key solves the problem. Maybe it's a version thing.

    Otherwise very helpful post, thank you!

    [...] of course had the answer.  Andrey Shchekin had the solution – DynamicProxyGenAssembly2 (http://blog.ashmind.com/2008/05/09/mocking-internal-interfaces-with-moq/).  Yeah, that was totally going to be my next guess.  [...]
