[VS 2010] How to convert an existing assembly to a ms unit test assembly ?

Question

In Visual Studio 2010 Pro, how can I easily convert a classic assembly to a ms unit test assembly ?

It there a flag to activate in the .csproj file ?

Answer 1

Unit Test Project is only Class Library which have classes with attribute [TestClass], and .csproj file doesn't have any flags. You can add class to your project and set attribute [TestClass] and it will be test class.

Answer 2

Hi there.

I'll be honest, your question doesn't make sense as such. Do you mean you want to convert a "classic" (e.g. .NET 2.0?) assembly into an MS Test assembly? The only way to do that is manually change the code in VS 2010.

To do this you will need to add a reference to:

C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

and import the Microsoft.VisualStudio.TestTools.UnitTesting namespace. Then, your classic assembly, you need to mark your code like this:

[TestClass]
public class YourTestClass
{

   [TestMethod]
   public void Test(){}
}

Using the MS Test attributes that you need.

EDIT: Doh!!! I gave you the path to wrong file, it should be:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies

Cheers. Jas.
