Unit Testing Events with Anonymous Delegates in .NET 2.0

How do you unit test your event code? You use Anonymous Delegates

Here’s a sample unit test that I’ve created that makes use of this technique:

    \[TestMethod()\]

    public void UpdateTestTimesTest()

    {

        object expected = UniSA.UniSAnet.SmartMark.DataAccess.DataItemChangedEventArgs.ChangeType.Update;

        object actual = null;

        UniSA.UniSAnet.SmartMark.DataAccess.TestComponent.DataItemChanged += delegate(object sender, UniSA.UniSAnet.SmartMark.DataAccess.DataItemChangedEventArgs e)

        {

            actual = e.Change;

        };

        Test test = UniSA.UniSAnet.SmartMark.DataAccess.TestComponent.GetTest(UnitTestingTestId);

        test.MinutesAllowed += 1;

        UniSA.UniSAnet.SmartMark.DataAccess.TestComponent.UpdateTestTimes(test);

        Assert.AreEqual(expected, actual);

    }
