C# 单元测试mvc登录

我一直在创建一个单元测试，但似乎失败了。有人能帮我为这个控制器创建一个单元测试吗

我已经试过各种方法了

    public class logInController : Controller
    {
        [HttpPost]
        public ActionResult Index(logInModel model)
        {
            if(ModelState.IsValid)
            {
                int match = 0;

                sqlConn = new SqlConnection(sqlConnString);

                sqlComm = new SqlCommand("spLogin", sqlConn);
                sqlComm.CommandType = CommandType.StoredProcedure;
                sqlComm.Parameters.AddWithValue("@userName", model.Username);
                sqlComm.Parameters.AddWithValue("@password", model.Password);

                SqlParameter userMatch = new SqlParameter("@userMatch", SqlDbType.Int);
                userMatch.Direction = ParameterDirection.Output;
                sqlComm.Parameters.Add(userMatch);

                sqlConn.Open();
                sqlComm.ExecuteNonQuery();

                match = Convert.ToInt32(sqlComm.Parameters["@userMatch"].Value);
                sqlConn.Close();

                if (match != 0)
                {
                    FormsAuthentication.SetAuthCookie(model.Username, false); 
                    return RedirectToAction("index","home");
                }
                else
                    ModelState.AddModelError("", "Invalid username or password");
            }
            return View();
        }
    }

现在我正在试这个

public void LoginTest() 
        {
            var controller = new logInController();
            var loginmodel = new logInModel
            {
                Username = "arwinortiz",
                Password = "123456"
            };
            FormsAuthentication.SetAuthCookie(loginmodel.Username, false);
            var result = (RedirectToRouteResult)controller.Index(loginmodel);
            result.RouteValues["action"].Equals("index");
            result.RouteValues["controller"].Equals("home");
            Assert.AreEqual("index", result.RouteValues["action"]);
            Assert.AreEqual("home", result.RouteValues["controller"]);
        }

首先，您需要将数据库和表单身份验证调用抽象到它们自己的关注点/接口中，以便对它们进行模拟。（羞耻……羞耻……）

完成后，您的控制器可以重构为

public class logInController : Controller {
    private IAuthenticationService authenticator;
    private IFormsAuthenticationService formsAuthentication;

    public MvcTestsController(IAuthenticationService userAuthentication, IFormsAuthenticationService formsAuthentication) {
        this.authenticator = userAuthentication;
        this.formsAuthentication = formsAuthentication;
    }

    [HttpPost]
    public ActionResult Index(logInModel model) {
        if (ModelState.IsValid) {
            bool match = authenticator.Authenticate(model.Username, model.Password);
            if (match) {
                formsAuthentication.SetAuthCookie(model.Username, false);
                return RedirectToAction("index", "home");
            } else
                ModelState.AddModelError("", "Invalid username or password");
        }
        return View();
    }
}

接下来，我们编写登录的单元测试

注意：我用于模拟依赖项和断言结果

[TestMethod]
public void LoginTest() {
    //Arrange
    var loginmodel = new logInModel {
        Username = "arwinortiz",
        Password = "123456"
    };
    var mockAuthenticator = new Mock<IAuthenticationService>();
    mockAuthenticator
            .Setup(x => x.Authenticate(It.Is<string>(s => s == loginmodel.Username), It.Is<string>(s => s == loginmodel.Password)))
            .Returns(true);
    var mockFormsAuthentication = new Mock<IFormsAuthenticationService>();

    bool isAuthCookieSet = false;
    mockFormsAuthentication
        .Setup(x => x.SetAuthCookie(It.Is<string>(s => s == loginmodel.Username), It.IsAny<bool>()))
        .Callback(() => { isAuthCookieSet = true; });

    var controller = new logInController(mockAuthenticator.Object, mockFormsAuthentication.Object);

    //Act
    var result = (System.Web.Mvc.RedirectToRouteResult)controller.Index(loginmodel);

    //Assert (using FluentAssertions)
    result.Should().NotBeNull(because: "the result should have redirected for entered user ");
    result.RouteValues["action"].ShouldBeEquivalentTo("index", because: "the redirection was to home.index action");
    result.RouteValues["controller"].ShouldBeEquivalentTo("home", because: "the result should redirect to home controller");
    isAuthCookieSet.Should().BeTrue(because: "auth cookie is set if the user was authenticated");
}

[TestMethod]
公共无效登录测试（）{
//安排
var loginmodel=新loginmodel{
Username=“arwinortiz”，
密码=“123456”
};
var mockAuthenticator=new Mock（）；
模拟验证器
.Setup（x=>x.Authenticate（It.Is（s=>s==loginmodel.Username），It.Is（s=>s==loginmodel.Password）））
.返回（真）；
var mockFormsAuthentication=new Mock（）；
bool-isAuthCookieSet=false；
模拟形式认证
.Setup（x=>x.SetAuthCookie（It.Is（s=>s==loginmodel.Username），It.IsAny（））
.Callback（（）=>{isAuthCookieSet=true；}）；
var控制器=新登录控制器（mockAuthenticator.Object、mockFormsAuthentication.Object）；
//表演
var result=（System.Web.Mvc.RedirectToRouteResult）controller.Index（loginmodel）；
//断言（使用FluentAssertions）
result.Should（）.NotBeNull（因为：“结果应该为输入的用户重定向”）；
result.RouteValues[“action”]应与“index”等效，因为：“重定向到home.index action”）；
result.RouteValues[“controller”]应与“home”等效，因为：“结果应重定向到home controller”）；
isAuthCookieSet.Should（）.BeTrue（因为：“如果用户经过身份验证，则设置了身份验证cookie”）；
}

向我们展示您的尝试，我们不会为您构建整个模型。您需要从控制器中提取db内容。只是说。。。

[TestMethod]
public void LoginTest() {
    //Arrange
    var loginmodel = new logInModel {
        Username = "arwinortiz",
        Password = "123456"
    };
    var mockAuthenticator = new Mock<IAuthenticationService>();
    mockAuthenticator
            .Setup(x => x.Authenticate(It.Is<string>(s => s == loginmodel.Username), It.Is<string>(s => s == loginmodel.Password)))
            .Returns(true);
    var mockFormsAuthentication = new Mock<IFormsAuthenticationService>();

    bool isAuthCookieSet = false;
    mockFormsAuthentication
        .Setup(x => x.SetAuthCookie(It.Is<string>(s => s == loginmodel.Username), It.IsAny<bool>()))
        .Callback(() => { isAuthCookieSet = true; });

    var controller = new logInController(mockAuthenticator.Object, mockFormsAuthentication.Object);

    //Act
    var result = (System.Web.Mvc.RedirectToRouteResult)controller.Index(loginmodel);

    //Assert (using FluentAssertions)
    result.Should().NotBeNull(because: "the result should have redirected for entered user ");
    result.RouteValues["action"].ShouldBeEquivalentTo("index", because: "the redirection was to home.index action");
    result.RouteValues["controller"].ShouldBeEquivalentTo("home", because: "the result should redirect to home controller");
    isAuthCookieSet.Should().BeTrue(because: "auth cookie is set if the user was authenticated");
}
