How do I unit test web api action method when it returns IHttpActionResult?

Question

Let\'s assume this is my action method

public IHttpActionResult Get(int id)
{
    var status = GetSomething(id);
    if (status)
    {
        return Ok();

Here Ok() is just a helper for the type OkResult which sets the response status to be HttpStatusCode.Ok...so you can just check if the instance of your action result is an OkResult...some examples(written in XUnit):

// if your action returns: NotFound()
IHttpActionResult actionResult = valuesController.Get(10);
Assert.IsType(actionResult);

// if your action returns: Ok()
actionResult = valuesController.Get(11);
Assert.IsType(actionResult);

// if your action was returning data in the body like: Ok("data: 12")
actionResult = valuesController.Get(12);
OkNegotiatedContentResult conNegResult = Assert.IsType>(actionResult);
Assert.Equal("data: 12", conNegResult.Content);

// if your action was returning data in the body like: Content(HttpStatusCode.Accepted, "some updated data");
actionResult = valuesController.Get(13);
NegotiatedContentResult negResult = Assert.IsType>(actionResult);
Assert.Equal(HttpStatusCode.Accepted, negResult.StatusCode);
Assert.Equal("some updated data", negResult.Content);
