    Mocking Constructors with JustMock

    In .NET there are two types of constructors, instance constructors and static constructors. Instance constructors are called when objects are instantiated, while static constructors get called before any member of the class is invoked for the first time.

    Automocking with JustMock

    Auto mocking containers are designed to reduce the friction of keeping unit test beds in sync with the code being tested as systems are updated and evolve over time. Background The Dependency Inversion Principle states: High level modules should not depend upon low level modules. Both should depend upon abstractions. Abstractions should not depend upon details. Details should depend upon abstractions. As more developers follow this and the rest of Robert Martin’s SOLID principles, methods and classes become much smaller with dependent objects injected into them, typically through constructor injection. As additional dependencies are needed (or the code is refactored to improve dependency isolation), the signatures of...

    Abstracting Dependencies with JustMock

    Unit tests are most effective when the System Under Test is isolated from its dependencies.  The best way to isolate your code (and make your code more SOLID) is through dependency injection. But even if you follow the rules of SOLID and inject all of the necessary dependencies in as interfaces, you are still faced with the fact that you depend on them. In order to test your code, something concrete has to be passed into the code in order for it to even compile.  Your production code will most likely use a factory to create concrete instances of the dependent interfaces, but that...

    Getting Started with NUnit, NUnit.Should, and JustMock

    Technorati Tags: TDD,Test Driven Development,JustMock,JustCode,NUnit,NUnit.Should,Mocking Before diving into mocking with JustMock, it’s important to note that JustMock is a mocking framework, and not a testing framework.  Test frameworks allow for creating Test Fixtures, which are .NET classes decorated with the appropriate attributes so they are picked up by a Test Runner.  Test are created within a Test Fixture by writing methods (with the appropriate attributes) that exercise your code (also referred to as the System Under Test) and report the results.  Test Runners are programs that will run your tests.  There are many free testing frameworks available for .NET developers, including MSTest (included...

    Fakes, Stubs, and Mocks

    In Doing Your First Mock, Mehfuz Hossain explained why you should use mocking to improve your unit tests and then used a real world example to demonstrate this technique. In this post, I will take you down a different path using other forms of stand-ins.
