Question

我试图模仿使用som泛型方法继承基类的Userservice。我无法模拟对RetrieveEntitiesTest的调用。

当我致电var validated = _userServiceMock.Object.ValidateUser(email, password);时，会执行RetrieveEntitiesTest的实际执行......

这可能吗？您可以在下面查看我的代码：

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);
    }
}

你没有正确设置你的模拟。使用It.IsAny（请参阅匹配参数部分）而不是新的QueryExpression：

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

使用moq 4.0模拟具有泛型类型的基类方法
