使用moq 4.0嘲笑泛型類型的基類方法

Question

我試圖嘲笑繼承了som泛型方法的基類的用戶服務。我無法嘲笑對RetrieveEntitiesTest的調用。

當我打電話var validated = _userServiceMock.Object.ValidateUser(email, password);的acctual實施RetrieveEntitiesTest的執行...

這可能嗎？ U可以代表我的代碼如下：

public class BaseService 
{ 
    public virtual bool RetrieveEntitiesTest<T>(QueryExpression query) 
    { 
     return false; 
    } 
} 

public class UserService : BaseService 
{ 
    public bool ValidateUser(string username, string password) 
    { 
     // adding query parameters 
     var query = new QueryExpression(); 

     var userCount = RetrieveEntitiesTest<User>(query); 

     return userCount > 0; 
    } 
} 

[TestFixture] 
public class UserServiceTests 
{ 
    private Mock<UserService> _userServiceMock; 

    [TestFixtureSetUp] 
    public void TestFixtureSetUp() 
    { 
     _userServiceMock = new Mock<UserService>(); 
    } 

    [Test] 
    public void ValidateLogin_ValidEmailValidPassword_ValidatedAndReturnsTrue() 
    { 
     string email = "user@company.com"; 
     string password = "password"; 
     var query = ..... 

     _userServiceMock.Setup(x => x.RetrieveEntitiesTest<User>(new QueryExpression())).Returns(true); 

     var validated = _userServiceMock.Object.ValidateUser(email, password); 

     Assert.IsTrue(validated); 
    } 
}

你沒有正確設置你的模擬。使用It.IsAny（請參閱匹配參數部分），而不是一個新QueryExpression：

_userServiceMock 
    .Setup(x => x.RetrieveEntitiesTest<User>(It.IsAny<QueryExpression>())) 
    .Returns(true);
