Use for WorkItemAttribute?

问题

I noticed there's an attribute Microsoft.VisualStudio.TestTools.UnitTesting.WorkItemAttribute available in visual studio testing (I'm using VS 2010 Premium and work items with TFS 2010.)

Marking a test method with a work item number sounds handy, but does it actually do anything? I can't tell if there's any tool support for it at all. I set one up like this:

[WorkItem(25788)]
[TestMethod]
public void TestSomethingSpecificToABug()
{
    ...

But no magic - I thought maybe the context menu on the test in the Test Results window might offer to open the work item, or Team Explorer might have a feature to search for tests. The MSDN documentation is no help either. What is this attribute good for?

回答1:

According to "Software Testing with Visual Studio® 2010" by Jeff Levinson (Addison-Wesley Professional, February 2011, ISBN-10: 0-321-73448-3):

This also means that one existing property should not be used anymore: Associated Work Items. This value is not reported to the data warehouse and therefore cannot be used for reporting. If you currently use this property, consider associating your test with an actual Test Case work item type.

So the answer is, don't use this with TFS 2010.

WorkItem Test Method attribute is not used for associating test methods to test cases. It is typically used to associate a test method with a bug. A related C# example from Code Index - How to discover ignored tests:

When using MSTest to build your suite of unit tests, you can use the attribute [Ignore] to tell the MSTest engine not to run a test instead of commenting it. You may also use the attribute [WorkItem(id)] to link the unit test to a bug database (such as TFS) item, so that you can trace why a particular test has been marked as ignored:

    [Ignore]
    [WorkItem(12345)] // bug 12345 describes why this test was ignored 
    [TestMethod]
    public void IgnoredButWithWorkItemTest()
    {
        //The actual code is not important;  
    }

It's to link the unit test back to a work item in TFS. I'd provide a link to more info but it seems it really is poorly documented.

I haven't used it myself but believe it can be used to generate reports on the status of work items.

回答4:

This isn´t needed anymore: in VS 2013 via CodeLens

Find linked work items (Alt + 7)

Find linked code reviews (Alt + 8)

Find linked bugs (Alt + 9)

To review a test's definition, double-click the test.

Oh! for those that cherish Lync:

Contact the owner of an item (Shift + F10)

回答5:

I really do remember, that I used this Attribute before and the test results have been attached to the respective WorkItem.

However, with Visual Studio 2012, it does not work anymore, or I forgot which mechanism was actually responsible for the magic. Could it be that this only works through the build server?

回答6:

Pulling attributes from the test binary is really useful when you have a home grown test harness built for running Selenium UI unit tests.

After a test failure, I can pull the WorkItemAttribute value using System.Reflection.MemberInfo.CustomAttributes and then look up the ID with the TFS API. If the work item is a bug and it's still active, I can auto-resolve the failure to that bug. In this manner, I can run the failing test every day and automatically resolve the failure to reduce randomization.
