ControllerTester<TController>

Instantiation:

using SparkyTestHelpers.AspNetMvc

    var homeController = new HomeController(/* with test dependencies */);
    var controllerTester = new ControllerTester<HomeController>(homeController);

It doesn't do anything on its own - just provides an Action(actionDefinitionExpression) method that's used to create a...

ControllerActionTester

    var controllerActionTester = 
        new ControllerTester<HomeController>(homeController).Action(x => x.Index);

ControllerActionTester has several .Test... methods used to assert that the controller action returns the expected IActionResult implementation. There are methods for all of the standard result types, plus the generic TestResult<TActionResultType> method:

• .TestContent(Action<ContentResult> validate)
• .TestEmpty(Action<EmptyResult> validate)
• .TestFile(Action<FileResult> validate)
• .TestJson(Action<JsonResult> validate)
• .TestPartialView(Action<PartialViewResult> validate)
• .TestRedirectToAction(string expecteActionName, Action<RedirectToRouteResult> validate)
• .TestRedirectToPage(string expectedPageName, Action<RedirectToPageResult> validate)
• .TestRedirectToRoute(string expectedRoute, Action<RedirectToRouteResult> validate)
• .TestView(Action<ViewResult> validate)
• .TestResult<TActionResultType>(Action<TActionResultType> validate)

Additional methods:

• .ExpectingViewName(string expectedViewName) - used with .TestView and .TestPartialView
• .ExpectingModel<TModelType>(Action<TModelType> validate) - using with .TestView and .TestJson
• WhenModelStateIsValidEquals(bool isValid) - used to test conditional logic based on ModelState.IsValid

All validate "callback" actions shown above are optional.

Examples

    var homeController = new HomeController(/* with test dependencies */);
    var controllerTester = new ControllerTester<HomeController>(homeController);

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

    controllerTester
        .Action(x => () => x.Details(3))
        .ExpectingViewName("Details")
        .ExpectingModel<Foo>(foo => Assert.IsTrue(foo.IsValid))
        .TestView();

    controllerTester
        .Action(x => () => x.Edit(updateModel))
        .WhenModelStateIsValidEquals(false)
        .TestRedirectToAction("Errors");

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