Mocking non-virtual methods in C#
.net, c#, mocking, testing, typemock
Solution
I am from Typemock, and I won't address the "Too Powerful" comments (although it's beyond me why people wouldn't want to use the best tool for the job).
Here's how Typemock Isolator works. Have you ever used a performance profiler? Isolator is a profiler. It hooks into the CLR and within the test run time, it changes methods. When a method gets JITted, it changes it, so when the method runs, before executing the original code, it asks: should I run it as originally intended, and if not, what should I do? And because of this specific technology, it can mock any .Net method and technology. That's it.
When you set a behavior using the API, the answer to the questions now becomes intersting, and changes the behavior at runtime of that method. Simple, but under the covers it's a lot of work:)
Isolator comes with a VS AddIn to make running the tests seamlessly within VS, and with a command line tool and MSBuild or NAnt tasks for usage in a build server.
I'll be happy to answer any other questions you may have.
Problem
I'm trying to test some classes I've made using mocks, but I've seen all free mocking frameworks in c# aren't able to mock non-virtual methods (if it is not in an interface). But, there's TypeMock who can do this, so it is possible. Can anyone show how to do it? I may even try to contribute to an open source framework if I can get this done. Thanks in advance
