Fixie - A Convention-based .NET Testing Framework

Fixie is a relative newcomer to the .NET testing framework space. It throws away the idea of marking elements of test code with attributes in favour of a conventions based approach.

At a high level, what this means is simply naming things in test projects following a defined default (customized conventions are also supported) convention.

A Fixie test class with a single test inside it would look like the following, notice the lack of attributes and even using statements.

namespace MyApplication.Tests
{
    public class SomeClassTests
    {
        public void ShouldDoSomething()
        {
        }
    }
}

After building the test will now show up in Visual Studio Test Explorer as the following screenshot shows.

Fixie knows this is a test because it matches the default conventions that come out of the box.

Fixie knows that this is a test class because it ends with “Tests” and it knows that the method is a test because it’s a public void method.

If these default conventions are not suitable for your project you can create your own custom conventions to customise the test discovery. There’s also a lot more to custom conventions, such as customising the test execution lifecycle and creating data-driven tests.
