Asserting Behavior with JustMock
JustMock is a great tool for abstracting dependencies in unit tests, and the new automocking feature makes it even faster to develop unit tests. Another great feature in JustMock and JustMock Lite is the capability to assert the behavior of your system under test. Traditional TDD (Test Driven Testing) unit testing typically tests for state. Did the user get logged in? Did the user’s shopping cart get loaded? Important tests, of course. But that only tests the end result of the method. If the user does NOT successfully login, and the cart is not reloaded, is that because the call to the repository was never called? Or because some error happened that didn’t reload the cart in this particular use case? The state of the application is correct, but is that because it executed the expected behavior, or because we got lucky?

Mocking Property Getters and Setters
In typical unit testing scenarios, mocking property getters and setters isn't high on the list of areas of concern. Where it usually comes into play is when an entity’s properties’ values (or the act of setting them) are part of the scaffolding, or behavior for the system under test.

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.

Mocking legacy code is hard. Especially, if it’s a third-party library and you have little control over how it’s written. It is even more difficult to unit test a type that is instantiated internally. One can argue that it should be refactored to accept dependencies via constructor injection. However, constraints such as time, budget, experience with the offending code, or even access to the source often prevent paying down the technical debt accumulated in these legacy systems. This post will show you how to mock an external library (concept) where it calls a login service class that cannot be sent...
