Using MS Test ClassInitialize() and TestInitialize() in VS2010 as opposed to NUnit

Question

I've used NUnit with VS2008, and now am adapting to MSTest on VS2010. I used to be able to create an object in TestSetup() and dispose of it in TestCleanup(), and have the object created each time a test method was run in NUnit, preventing me from duplicating the code in each test method.

Is this not possible with MSTest? The examples I am finding using the ClassInitialize and ClassCleanup and TestInitialize and TestCleanup attributes only show how to write to the console. None show any more detailed use of these attributes.

Answer 1

Here is a simple example using TestInitialize and TestCleanup.

[TestClass]
public class UnitTest1
{
    private NorthwindEntities context;

    [TestInitialize]
    public void TestInitialize()
    {
        this.context = new NorthwindEntities();
    }

    [TestMethod]
    public void TestMethod1()
    {
        Assert.AreEqual(92, this.context.Customers.Count());
    }

    [TestCleanup]
    public void TestCleanup()
    {
        this.context.Dispose();
    }
}
