How to pass specific UserContext in unit testing of controller action

Question

I have the following controller action

        [Route(ActionName.Create)]
        public async Task<ActionResult> Create()
        {
            .... 
            if (!UserContext.Roles.HasFlag(GroupsEnum.Admin))
            {
                throw new UnauthorizedAccessException("Permission Denied");
            }
            ... 
        }

I have following in xxxxControllerTests.cs

        [TestMethod]
        public async Task Can_Request_Create()
        {

            ViewResult result = (ViewResult)await MockController.Object.Create();
            ...
            ...
        }

when I run the unit test I get unauthorized access exception raised. How can pass UserContext while mockController, so controller action will be executed with specific user context?

Normally when you're instantiating the Controller you're testing, you can initialize it like this:

var controllerToTest = new MyController() {
    ControllerContext = new ControllerContext {
        HttpContext = //assign mock context,
        UserContext = //assign mock context
    }
};
var result = controllerToTest.Create();

However this line of code makes me think you're testing an already mocked controller:

ViewResult result = (ViewResult)await MockController.Object.Create();

The .Object call makes me think you have a Mock<MyController> in there and that's not right. You're not testing your own controller.

Thanks, @Simmetric, clue you provided give me an idea of how to fix it. all fixed now :). I will update the question with the solution. Thanks. — Developer, Feb 16 '21 at 23:19

You should Mock your dbContext.
