Maybe you\u2019ve already seen an exception like this:<\/p>\n

What I\u2019ve tried is to create a mock-object with Rhino-Mock<\/a>. Since this interface is only intended for usage within the assembly it\u2019s declared as internal interface. So Rhino-Mock fails and I really don\u2019t want to create a mock manually. The quickest and dirtiest way would be to make the interface public. But I really don\u2019t want to leak internal stuff just for tests.<\/p>\n

So the second approach is to make the internals visible to Rhino-Mocks.<\/p>\n

But it will fail as well. Since Rhino uses Castle-Proxies, I tried:<\/p>\n
\n
[assembly: InternalsVisibleTo(\"Castle.DynamicProxy\"<\/span>)]<\/pre>\n<\/blockquote>\n
It still won\u2019t work. The reason for this is simple. The Mock-Factory has to generate code. The generated code is hosted in a separate assembly. So you have to make the dynamic assembly visible to your code under test.<\/p>\n
\n
[assembly: InternalsVisibleTo(\"DynamicProxyGenAssembly2\"<\/span>)]<\/pre>\n<\/blockquote>\n
This is similar with other mock frameworks or proxy-frameworks.<\/p>\n
