  • Over Specification in Tests

    I've gotten the chance to visit and consult various companies and I see this all the time: Over specification in tests, especially when doing mocks and stubs . One main reason for that is that people use their stub as a mock object (stubs are fake objects that we will not assert on so that we can...

  • A sneak Preview of Typemock Racer : Thread Deadlock Finder

    Here's a sneak preview of the upcoming Typemock Racer product, which I'm currently working on. We should be out in private CTP in a couple of weeks I hope.

  • Introducing Depender - Testability Problem Finder

    Depender is a tool that I created to illustrate several concepts both for my book and both for my training classes. I think it should prove valuable (as it gets more and more features) to anyone who is trying to write tests for existing code.   Depender allows you to load an assembly and inspect...

  • Over-testable systems, and mocks as bad test smells

    This is an interesting problem I've been running into at work. Sometimes we would try to write a test against the system or a component and we would literally have too many choices of how to write it or where to "intercept" or "inject" our stubs or mock objects.  In a way...

  • Unit testing vs. Integration Testing : The Restaurant Analogy

    Here's an analogy I came up with to explain the difference between unit tests and integration tests. Imagine going to a restaurant with a bunch of your friends. there are some couples there as well as singles. At the end of the meal, it is time to pay. Unit testing is like giving a separate bill...

  • "Swapping" instead of "Injecting" calls between classes

    Eli Lopian, Typemock CEO and awesome Coder, just created a nice little API wrapper around Typemock Isolator that would allow a very simple and readable "Swapping" effect between classes. It would allow you to write code like this:     [ Test ]       ...

  • NullObject.For<T> - As simple as it gets, but no simpler

    This NullObject Factory from Paul is very nice, simple and clean in its design. I really like it and I can see many uses for it, in parallel with working with your standard mocking framework or IoC Container Implementation .   here is a little usage example (last line): var controller = new AccountController...

  • Pros and Cons and of using an Auto Mocking container in your tests

    In regards to my post about injecting mocks and stubs using a container in your tests, Dave asks in the comments: Why would you want to do this in the first place? Here are the things I can think about right now (pros and cons). I'd love to hear your thoughts. Pros for using a container in your tests...
