How to find all Shared Step references for a given ITestCase object in TFS

Given that I have a ITestCase object obtained like so

ITestCase tc = project.TestCases.Find(2034);

Where project is an object of type ITestManagementTeamProject obtained by

TfsTeamProjectCollection tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri(tfsLocation));
ITestManagementService testService = tfs.GetService<ITestManagementService>();
return testService.GetTeamProject(projectName);

How do I get all the shared step references(don't even know if there was one in the first place) for that particular test case, considering that I don't have any prior state knowledge about that test case.

Please help.

Solution

There is a ISharedStepReference Interface to call a shared step from a test case. You just need to use FindSharedStep method return the shared step definition from the server. A sample code for your reference:

public ISharedStep tstSharedStep { get; private set; }

public ISharedStepReference tstSharedStepRef { get; private set; }

    foreach (ITestAction tstAction in tstCase.Actions)
            {
                tstSharedStep = null; 
                tstSharedStepRef = tstAction as ISharedStepReference;
                    if (tstSharedStepRef != null)
                    {
                        tstSharedStep = tstSharedStepRef.FindSharedStep();
                        foreach (ITestAction tstSharedAction in tstSharedStep.Actions)
                        {
                            ITestStep tstSharedTestStep = tstSharedAction as ITestStep;
                            resultData.Step = Regex.Replace(tstSharedTestStep.Title, @"<[^>]+>|&nbsp;", "").Trim();
                            resultData.ExpectedResult = Regex.Replace(tstSharedTestStep.ExpectedResult, @"<[^>]+>|&nbsp;", "").Trim();

                        }
                    }
                    else {
                     // regular step action
                    }

}
