c# - 我该如何设置(最小起订量设置)

Question

我想测试返回用户密码问题的代码部分。因此，我使用 Moq 制作了成员(member)提供程序的模型。

我认为我不需要向您展示实际代码，只需要展示它的测试部分。

// Arrange
var membershipMock = new Mock<MembershipProvider>();
membershipMock.Setup(m => m.GetUser("test", false).PasswordQuestion).Returns("Password");
authentication.Authenticate.Provider = membershipMock.Object;

// Act
var actual = authentication.PasswordRecoveryStep1(It.IsAny<string>());

// Assert
Assert.That(actual, Is.EqualTo("Password"));

所以当我在 Nunit 中运行它时，我得到了这个:

Test.Controllers.AuthenticationControllerTest.Test_If_Password_Recovery_Setp1_Returns_Users_PasswordQuestion:
System.NotSupportedException : Only property accesses are supported in intermediate invocations on a setup. Unsupported expression m.GetUser("test", False).

at Test.Controllers.AuthenticationControllerTest.Test_If_Password_Recovery_Setp1_Returns_Users_PasswordQuestion() in D:\MvcApplication9\Test\Controllers\AuthenticationControllerTest.cs:line 186

所以我猜这是因为我试图访问的属性。我不确定如何设置它。我对 lambda 不是很好(并且还没有找到关于它们的教程)所以我不确定我是否可以通过一些不同的方式来安排它以使其工作。

或者如果我完全没有达到目标。

答案在异常消息中:

... Only property accesses are supported in intermediate invocations on a setup ...

试试这个:

var user = new Mock<MemberShipUser>();
user.SetupGet(x => x.PasswordQuestion).Returns("Password");

membershipMock.Setup(m => m.GetUser("test", false)).Returns(user.Object);
