Question

我想在Asp.net中测试帐户控制器 帐户控制器是身份的一部分 是否需要测试帐户控制器？

Answer 1

免责声明：我在Typemock工作。

在使用Typemock Isolator时，一般情况下测试ASP.net控制器和特别是帐户控制器也很容易。以下是对帐户控制器的Login方法的测试示例：

测试方法（取自VS2015 MVC模板）：

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }

    var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
    switch (result)
    {
        case SignInStatus.Success:
            return RedirectToLocal(returnUrl);
        case SignInStatus.LockedOut:
            return View("Lockout");
        case SignInStatus.RequiresVerification:
            return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
        case SignInStatus.Failure:
        default:
            ModelState.AddModelError("", "Invalid login attempt.");
            return View(model);
    }
}

测试：

[TestMethod, Isolated]
public async Task TestWhenLoginIsBad_ErrorMessageIsShown()
{
    // Arrange
    // Create the wanted controller for testing 
    var controller = new AccountController(); 
    var loginData = new LoginViewModel { Email = "support@typemock.com", Password = "password", RememberMe = false };

    // Fake the ModelState
    Isolate.WhenCalled(() => controller.ModelState.IsValid).WillReturn(true);

    // Ignore AddModelError (should be called when login fails)
    Isolate.WhenCalled(() => controller.ModelState.AddModelError("", "")).IgnoreCall();

    // Fake HttpContext to return a fake ApplicationSignInManager
    var fakeASIM = Isolate.WhenCalled(() => controller.HttpContext.GetOwinContext().Get<ApplicationSignInManager>()).ReturnRecursiveFake();

    // When password checked it will fail. Note we are faking an async method
    Isolate.WhenCalled(() => fakeASIM.PasswordSignInAsync(null, null, true, true)).WillReturn(Task.FromResult(SignInStatus.Failure));

    // Act
    var result = await controller.Login(loginData, "http://www.typemock.com/");

    // Assert
    // The result contains login data, doesn’t redirect
    Assert.IsInstanceOfType(result, typeof(ViewResult));
    Assert.AreSame(loginData, (result as ViewResult).Model);
    // Make sure that the code added an error
    Isolate.Verify.WasCalledWithExactArguments(() => controller.ModelState.AddModelError("", "Invalid login attempt."));
}

对于一般的单元测试，您可以查看本文

有关帐户控制器的测试，请查看以下文章

http://blogs.interknowlogy.com/2014/08/21/mvc-series-part-2-accountcontroller-testing/

   [Test]
   public void ShouldNotAcceptInvalidUser()
  {
  // Arrange
  Mock<IMembershipService> membership = new Mock<IMembershipService>();
  membership.Setup(m => m.ValidateUser(It.IsAny<string>(), It.IsAny<string>()))
          .Returns(false);
  Mock<IFormsService> forms = new Mock<IFormsService>();
var logonModel = new LogOnModel() { UserName = "", Password = "" };
var controller = new AccountController(membership.Object, forms.Object);

// Act
var result = controller.LogOn(logonModel, "") as ViewResult;

// Assert
Assert.That(result.ViewName, Is.EqualTo("Index"));
Assert.False(controller.ModelState.IsValid);
Assert.That(controller.ModelState[""], 
            Is.EqualTo("The user name or password provided is incorrect."));}
