我创建了一个以前的Test方法,该方法在单个Data Access上为两个模拟对象进行了设置,并且运行良好。又有一个具有相同场景的案例,但是结果失败了。
这是测试方法:
Diccionario
这是业务规则:
[Test]
public void UpdateUserPassword_WhenInputsAreCorrect_ReturnsQuerySuccessMessage()
{
UpdatePasswordModel input = new UpdatePasswordModel()
{
UserName = "john.doe",
NewPassword = "password1", //password1
PreviousPassword = "password" //password
};
Mock<IUserDataAccess> user = new Mock<IUserDataAccess>();
Mock<IDailyTimeInDataAccess> timeIn = new Mock<IDailyTimeInDataAccess>();
Mock<IDailyTimeOutDataAccess> timeOut = new Mock<IDailyTimeOutDataAccess>();
user.Setup(x => x.UpdatePassword(10000, input.NewPassword)).Returns("User record updated.");
user.Setup(x => x.GetUser(input.UserName)).Returns(new User()
{
UserKey = 10000,
UserName = "john.doe",
UserPassword = "LTg9BIob8urwz643K5+pBA=="
});
ILoginBusinessRules app = new LoginBusinessRules(user.Object, timeIn.Object, timeOut.Object);
var output = app.UpdateUserPassword(input);
Assert.AreEqual("User record updated.", output);
}
测试返回失败。进一步的调试告诉我,这里的这一行返回null:
public string UpdateUserPassword(UpdatePasswordModel model)
{
if (model == null)
{
return "No data to process.";
}
if (string.IsNullOrEmpty(model.UserName))
{
return "Username is empty.";
}
if (string.IsNullOrEmpty(model.NewPassword))
{
return "New Password is empty.";
}
if (string.IsNullOrEmpty(model.PreviousPassword))
{
return "Previous Password is empty.";
}
var user = _userDataAccess.GetUser(model.UserName);
if (user == null)
{
return "User not found.";
}
if (user.UserPassword != EncryptPassword(model.PreviousPassword))
{
return "Previous password does not match.";
}
else
{
user.UserPassword = EncryptPassword(model.NewPassword);
user.UpdateDttm = DateTime.Now;
user.UpdateUserId = model.UserName;
var result = _userDataAccess.UpdatePassword(user.UserKey, user.UserPassword);
return result;
}
}
任何帮助都将不胜感激!

Setup
使用input.NewPassword
,根据测试,它是
UpdatePasswordModel input = new UpdatePasswordModel() {
//...
NewPassword = "password1",
//...
};
//...
user.Setup(x => x.UpdatePassword(10000, input.NewPassword)).Returns("User record updated.");
//...
但是在被测方法中,该方法用另一个值调用
//...
user.UserPassword = EncryptPassword(model.NewPassword);
//...
var result = _userDataAccess.UpdatePassword(user.UserKey, user.UserPassword);
与设置中预期的不匹配。
当未按预期方式调用模拟成员时,它将返回默认的返回类型,在这种情况下,返回类型为 null
您需要确保设置期望值中使用了正确的值
例如
user
.Setup(x => x.UpdatePassword(10000, EncryptPassword(input.NewPassword)))
.Returns("User record updated.");
或使用类似It.IsAny<T>()
user
.Setup(x => x.UpdatePassword(10000, It.IsAny<string>()))
.Returns("User record updated.");

要回答帖子中的问题,可以,您可以使用任何与输入类型匹配的对象。您的代码并不真正知道“模拟”对象与“真实”对象之间的区别。
