Can you record accessed methods in Visual Studio?

Question

I'm retroactively documenting and writing unit tests for some C# code. I would like to determine what code is actually being used and when.

In Visual Studio 2012, is there a way to record all the methods accessed and in what order while walking through specific scenarios?

You could run your application with a profiler attached, which will give you all accessed methods, call chains, counts, etc.

The Visual Studio Profiler will give you the time spent in each method, and let you inspect the call heirarchy. I don't know if it will give you the exact order they were called in though.

EDIT: Apparently attaching the profiler to a running unit test is harder in VS2012.

Are you wanting to execute a test method that make sure that a particular method on a class was invoked ? If so i dont know of a way to do it in VS alone, but you can use a mock framework to create dependency mocks and check values on them. Here is a snippet of a unit test:

 [TestMethod]
        public void HttpPostPrivacyPolicyFacadeSvcErrorTest()
        {
            var controller = ControllerHelper.GetRouteController();
            controller.Session[SessionVariable.User] = new UserInfo() { UserName = Config.Data.Username };

            var idmSvcMock = new Mock<IUserServiceDAO>();
            var facadeSvcMock = new Mock<IFacadeSvcDAO>();

            //setup the facade mock to throw exception to simulate FacadeServiceException
            facadeSvcMock.Setup(x => x.SetPrivacyAcceptanceStatus(It.IsAny<UserInfo>())).Throws<Exception>();
            var userCollectorMock = new Mock<IUserInfoCollector>();
            userCollectorMock.Setup(x => x.GetUserInfo()).Returns(new UserInfo() { UserName = Config.Data.Username });




            controller.FacadeSvc = facadeSvcMock.Object;
            controller.UserServiceDAO = idmSvcMock.Object;
            controller.UserCollector = userCollectorMock.Object;
            controller.DefaultErrorId = "Route_errors_Unabletoprocess";

            //action
            var res = controller.Privacy(new FormCollection());

            //assert
            //make sure we go to the right controller, action, with the correct params.
            res.AssertActionRedirect().ToController("Errors").ToAction("Index").WithParameter("id", "Route_errors_Unabletoprocess");
            //did we call setprivacy once on the mock?
            facadeSvcMock.Verify(x => x.SetPrivacyAcceptanceStatus(It.IsAny<UserInfo>()), Times.Exactly(1));

In the test above i check that SetPrivacyAcceptance was invoked once and only once on my facadeSvcMock instance. More on moq here: Moq

this block of code is actually checking how many times SetPrivacyAcceptanceStatus was invoked: //did we call setprivacy once on the mock? facadeSvcMock.Verify(x => x.SetPrivacyAcceptanceStatus(It.IsAny()), Times.Exactly(1));

the It.IsAny() is the one parameter to that method, so the line above says basically "For any input parameter of type UserInfo verify that we invoked SetPrivacyAcceptanceStatus exactly once."
