I’m not the only one!

Ben, since MSTest‘s functionality dwarfs that of NUnit’s I’ve found it relatively easy to have most of my tests run in both MSTest and NUnit. Of course, where I used NUnit’s more advanced functionality, I just disable the test in MSTest. Yes, its kind of a hack, but it works.

Each of my test files have using statement sections like this:

#if NUNIT
using TestClassAttribute = NUnit.Framework.TestFixtureAttribute;
using TestMethodAttribute = NUnit.Framework.TestAttribute;
using TestInitialize = NUnit.Framework.SetUpAttribute;
using NUnit.Framework;
#else
using TestFixtureAttribute = Microsoft.VisualStudio.TestTools.UnitTesting.TestClassAttribute;
using TestAttribute = Microsoft.VisualStudio.TestTools.UnitTesting.TestMethodAttribute;
using Microsoft.VisualStudio.TestTools.UnitTesting;
#endif

Then I maintain two project files. One is a MSTest project, and only opens in Team System edition. The other is a standard Class Library project - the typical NUnit test project. The later defines NUNIT in its project settings. By using type aliases like this, I can use either NUnit or MSTest attributes in my test fixtures. Of course any tests using NUnits Constraint Model Assertions won’t work in MSTest so I’ll either #if def out those tests, or I won’t include the entire fixture in the MSTest project.
