How to return default(Type) in runtime – a TDD example in four unit tests

I’ve found this question while going over my old StackOverflow answers:I'm using reflection to loop through a Type's properties and set certain types to their default. Now, I could do a switch on the type and set the default(Type) explicitly, but I'd rather do it in one line. Is there a programmatic equivalent of default?I … Continue reading How to return default(Type) in runtime – a TDD example in four unit tests →

Find out where is the method that was called unexpectedly using fake objects

Every Isolation/Mocking framework out there can verify that a method of a fake object was called and not less important make sure that certain methods are not called. Let’s say that I want to make sure that a method didn’t encounter any errors during execution but verifying that logger.Error was not called: [TestFixture]public class MyClassTests{ … Continue reading Find out where is the method that was called unexpectedly using fake objects →

How to run your unit tests as part of TFS build

There are several solutions to solve this issue from downgrading my project to use … Continue reading How to run NUnit tests created with VS2010 and .NET 4 →

#Nose – the unit test discovery tool

One of the benefits of programming in C#/VB.NET is amount of tools available - from Visual Studio to build servers to unit testing frameworks it seems that there is a tool for every job. I thought that my .NET tool belt has everything I need until recently, while learning Python (actually IronPython) I’ve discovered Python-Nose … Continue reading #Nose – the unit test discovery tool →
