Question

Using MSTest how can I verify the exact error message coming from a test method? I know [ExpectedException(typeof(ApplicationException), error msg)] doesn\'t co

In MSTest there's no built-in way of doing it. This is about as 'elegant' as it gets:

[TestMethod]
public void Test8()
{
    var t = new Thrower();
    try
    {
        t.DoStuffThatThrows();
        Assert.Fail("Exception expected.");
    }
    catch (InvalidOperationException e)
    {
        Assert.AreEqual("Boo hiss!", e.Message);
    }
}

However, you could consider porting xUnit.NET's Assert.Throws API to a custom library - that's what we did.

You could also go to Microsoft Connect an vote on this suggestion.
