I’m in the process of resolving a unit test backlog for the Time Tortoise idle time feature. Last month, I explained why it’s acceptable in some situations to delay writing unit tests. I also covered a couple of unit testing best practices: interface-based design and minimizing the size of code-behind classes.

Over the past two weeks, I covered some challenges related to .NET assembly dependencies.

This week: more details on the idle time unit tests.

Last week, I wrote about techniques to find a list of the .NET assemblies that xUnit.net needs to run unit tests. To review:

• When Visual Studio compiles a unit test project, it doesn’t copy all of the required dependencies into the output directory.
• Therefore, we need a way to manually find these dependencies.
• To find the dependencies, we can attempt to run unit tests and look for detailed error messages. One messages is shown when a FileLoadException occurs. Another one is found in Assembly Binding Log Viewer output: “All probing URLs attempted and failed.” Using these messages, we can manually copy dependencies to the unit test project output directory.
• If these debugging techniques uncover the need for two or more assemblies with different versions, binding redirection can be used to define a single version to use.

Missing dependencies prevent Visual Studio from discovering unit tests (i.e., finding them so they can be listed in Test Explorer). Using these debugging techniques, we should be able to successfully discover all of the unit tests in a project. The next step is to try to run the discovered tests.
