What should we test? There is very little value-add in spending hours adding tests to things that might not need it. I tend to follow the WELC approachfocusing on adding tests to either areas of code that I am about to work on, or areas that I know need some test coverage.
I really like it. These classes really just provide an in-code way of configuring the various conventions in ASP. All of the code that matters is in the Controllers folder, and in particular the ProductsController class, which is the main API for the project.
This is the class we will unit test today. For me a unit test is the smallest bit of code that I can test in isolation from other bits of code. NET code, this tends to be classes and methods. When we create tests that bring up large parts of our system, or of the environment, we are really creating integration tests.
Creating a testable, cohesive, decoupled design is important to me. It is the only way to achieve the design goal of simplicity maximizing the amount of work not done.
But in this case we will be adding tests to an existing system. To make the point, I will try to avoid changing the system if I can. Because of this we may find ourselves occasionally creating integration tests because we have no choice.
But we can and should use that feedback to think about the design of what we have and whether it needs some refactoring.
Straight away I see the first problem: The IProductRepository is private and static. Calling new ProductRepository in the controller is not the best design, because it ties the controller to a particular implementation of IProductRepository.
In a future post I will show how to resolve this dependency with something like Ninject, but for now we will just use manual dependency injection by creating a testing constructor.
First I will make the repository field non-static.
Then I add a second constructor which allows me to pass in a repository. Finally I update the default constructor to initialize the field with an instance of the concrete ProductRepository class. This approach of creating a testing constructor is a good first step, even if you are going to later add a dependency injection framework.
It allows us to provide a stub value for the dependency when we need it, but existing clients of the class can continue to use the default constructor. Now the class looks like this. For these tests I will be using the xUnit.
After using NuGet to get an xUnit. Testing all of the methods except for PostProduct is pretty straightforward. GetAllProducts This is a very simple method that just returns whatever the repository gives it.
No transformations, no deep copies, it just returns the same IEnumerable it gets from the repository. The first confirms that it returns what the repository gives it, and the second confirms that it will throw if the repository returns null.
DeleteProduct ; Assert.
PostProduct The PostProduct method is where things get interesting. My first attempt at a test looked like this: You end up getting a NullReferenceException thrown by Request. CreateResponse because it expects a fair amount of web config stuff to have been assembled.
This is a bummer, but it is what it is. We had to assemble a whole bunch of interesting configuration and routing classes to make the Request. CreateResponse method happy, but it did work. The first test we wrote looked like this: Since I knew I needed to make a few more tests to adequately pin the behavior of PostProduct, I refactored out the ugly config code into a private method in the test class called SetupControllerForTests.The Red Hat Enterprise Linux Technical Notes list and document the changes made to the Red Hat Enterprise Linux 5 operating system and its accompanying applications between Red Hat Enterprise Linux and minor release Red Hat Enterprise Linux However, the connector will write the encoded string into the main XML file instead of the included password file (and thus overwriting the "include" line).

Subversion is an Open Source source control system. Check out this list of great Open Source software, where all the tools are centered around Software management and Engineering. If you know only very little about source control and/or Subversion, read the free book Version Control with Subversion and in particular chapters 1.
