Controller Testers

ControllerTester<T> and ApiControllerTester<T> test action methods of controllers that inherit from System.Web.Mvc.Controller and System.Web.Http.ApiController respectively.

The general syntax is:

tester
    .Action(action selection expression)
    .When(optional code to "arrange" test conditions)
    .Expecting...(optional code to set up assert expectations)
    .Test...()

Examples

//ControllerTester:

    moviesControllerTester
        .Action(x => x.Index)
        .TestView();

    moviesControllerTester
        .Action(x => () => x.Details(3))
        .ExpectingViewName("Details")
        .ExpectingModel<Movle>(movie => Assert.AreEqual("Office Space", movie.Title))
        .TestView();

    moviesControllerTester
        .Action(x => x.Edit(testInvalidModel))
        .WhenModelStateIsValidEquals(false)
        .TestRedirectToAction("Errors");

    moviesControllerTester
        .Action(x => () => x.Edit(testValidModel))
        .WhenModelStateIsValidEquals(true)
        .ExpectingViewName("UpdateSuccessful")
        .TestRedirectToRoute("Home/UpdateSuccessful");

//ApiControllerTester:

   moviesApiControllerTester 
        .Action<IEnumerable<Movie>>(x => x.GetAllMovies)
        .Test(movies => Assert.AreEqual(100, movies.Count());

   moviesApiControllerTester 
        .Action(x => () => x.Get)
        .WhenRequestHasQueryStringParameters(new QueryStringParameter("id", 3))
        .TestOkNegotiatedContentResult<Movie>(movie => Assert.AreEqual("Office Space", movie.Title));

    moviesApiControllerTester
        .Action(x => () => x.Update(updateModel))
        .WhenModelStateIsValidEquals(false)
        .TestBadRequestResult();

    moviesApiControllerTester
        .Action(x => () => x.Update(updateModel))
        .WhenModelStateIsValidEquals(true)
        .TestOkResult();

RouteTester

RouteTester and RoutingAsserter provide methods to assert that a given relative URL maps to the expected RouteData.Values. The RoutingAsserter.AssertMapTo overloads provide multiple ways to specify the expected values...

Constructors

  • public RouteTester(Action<RouteCollection> routeRegistrationMethod)
  • public RouteTester(AreaRegistration areaRegistration)
using SparkyTestHelpers.AspNetMvc.Routing;
. . .
    var routeTester = new RouteTester(RouteConfig.RegisterRoutes);
    var areaRouteTester = new RouteTester(new FooAreaRegistration());

methods

  • .ForUrl(string relativeUrl) - creates a new RoutingAsserter instance.

RoutingAsserter

methods

  • AssertMapTo(IDictionary<string, object> expectedValues)
  • AssertMapTo(object routeValues)
  • AssertMapTo(string controller, string action, (object id)) - id defaults to null
  • AssertMapTo<TController>(Expression<Func<TController, Func<ActionResult>>> actionExpression)
  • AssertRedirectTo(string expectedUrl, (HttpStatusCode *expectedStatusCode)) - expectedStatusCode defaults to HttpStatusCode.Redirect (302)

examples

routeTester.ForUrl("Default.aspx")
    .AssertRedirectTo("Home/LegacyRedirect");

// alternate syntaxes for asserting Home/Index routing:
routeTester.ForUrl("Home/Index")
    .AssertMapTo(new Dictionary<string, object> 
        { { "controller", "Home" }, { "action", "Index" }, { "id", null } );
routeTester.ForUrl("Home/Index")
    .AssertMapTo(new {controller = "Home", action = "Index"});
routeTester.ForUrl("Home/Index")
    .AssertMapTo("Home", "Index");
routeTester.ForUrl("Home/Index")
    .AssertMapTo<HomeController>(x => x.Index);

// alternate syntaxes for asserting Order/Details/3 routing:
routeTester.ForUrl("Order/Details/3")
    .AssertMapTo(new Dictionary<string, object> 
        { { "controller", "Order" }, { "action", "Details" }, { "id", 3 } );
routeTester.ForUrl("Order/Details/3")
    .AssertMapTo(new {controller = "Order", action = "Details", id = 3 });
routeTester.ForUrl("Order/Details/3")
    .AssertMapTo("Order", "Details", 3);
routeTester.ForUrl("Order/Details/3")
    .AssertMapTo<OrderController>(x => () => x.Details(3));
