using MS Test in class library project

Hi,

I create a TestFramework project and two additional unit test projects.
I want to create a test framework and let two unit test projects use a bunch of helpers classes in a test framework project.
However, one of classes in a test framework contains a method that always has to run first before all other unit tests run.
So I wanted to use [AssemblyInitializer] fixture in this class in a test framework, but even if I add 'using Microsoft.VisualStudio.TestTools.UnitTesting;' directive, I can add any fixtures.

Is there any way I can add MS test fixture on a class in a class library project?

I doubt that this will do what you want anyway. According to the documentation:

Identifies a method that contains code to be used before all tests in the assembly have run and to allocate resources obtained by the assembly. This class cannot be inherited.

Your assembly, in this case, would be the TestFramework project. Each other project in your solution will be its own assembly.

What I would suggest is to put your common code into a function that is in the shared library, and have methods defined within your tests, tagged with the AssemblyInitializer attribute, that call out to the shared code. (This shared code is added as a reference to each of your unit test projects.) You cannot inherit the AssemblyInitializer attribute, so I think this would be the best you can get.

e.g.

Shared Code
#define DEBUG

namespace ClassLibrary1
{
    public class Class1
    {
        public void SharedMethod()
        {
            System.Diagnostics.Debug.WriteLine($"{nameof(Class1)}.{nameof(SharedMethod)} running...");
        }
    }
}

Open in new window


Unit Test Project 1
#define DEBUG

using ClassLibrary1;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [AssemblyInitialize]
        public static void Initialize(TestContext context)
        {
            Class1 instance = new Class1();

            instance.SharedMethod();
        }

        [TestMethod]
        public void TestMethod1()
        {
            System.Diagnostics.Debug.WriteLine($"{nameof(UnitTest1)}.{nameof(TestMethod1)} running...");
        }
    }
}

Open in new window


Unit Test Project 2
#define DEBUG

using ClassLibrary1;
using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace UnitTestProject2
{
    [TestClass]
    public class UnitTest2
    {
        private static TestContext ctx;

        [AssemblyInitialize]
        public static void Initialize(TestContext context)
        {
            Class1 instance = new Class1();

            ctx = context;
            instance.SharedMethod();
        }

        [TestMethod]
        public void TestMethod2()
        {
            System.Diagnostics.Debug.WriteLine($"{nameof(UnitTest2)}.{nameof(TestMethod2)} running...");
        }
    }
}
