我有以下测试不断失败，我不知道为什么:(
[TestClass]
public class UserTest
{
private Mock<IRolodexDA> _rmock = new Mock<IRolodexDA>();
private Mock<ICompanyDA> _cmock = new Mock<ICompanyDA>();
private Mock<IUserSettingsDA> _umock = new Mock<IUserSettingsDA>();
private Mock<ICLObjectContext> _clmock = new Mock<ICLObjectContext>();
[TestInitialize]
public void Setup()
{
ObjectFactory.Inject(typeof(IRolodexDA), _rmock.Object);
ObjectFactory.Inject(typeof(ICompanyDA), _cmock.Object);
ObjectFactory.Inject(typeof(IUserSettingsDA), _umock.Object);
ObjectFactory.Inject(typeof(ICLObjectContext), _clmock.Object);
}
[TestMethod]
public void Get_does_not_return_valid_user_when_not_enabled()
{
string email_add = "theguy@totest.com";
List<RolodexDomain> items = new List<RolodexDomain>();
items.Add(new RolodexDomain() {rdx_contact_name = "joe blogs", rdx_auto_key = 1, email_address = email_add, cv_udf_030 = null , sdf_rdx_001 = null });
_rmock.Setup(s => s.Get()).Returns(items.AsQueryable());
var result2 = _rmock.Object.Get();
var user = new CLAPortal.Service.UserService();
var result = user.Get(email_add);
Assert.IsNull(result);
}
在我的服务层中，我有以下代码：
public class UserService : IUserService
{
private readonly IRolodexDA _rolodexDA = Resolver.GetConcreteInstanceOf<IRolodexDA>();
private readonly IUserSettingsDA _userSettingsDA = Resolver.GetConcreteInstanceOf<IUserSettingsDA>();
private readonly ICompanyDA _companyDA = Resolver.GetConcreteInstanceOf<ICompanyDA>();
private ICLObjectContext _context = Resolver.GetConcreteInstanceOf<ICLObjectContext>();
public UserDomain Get(string email_address)
{
UserDomain user = null;
var rdx = GetRolodexForUser(email_address);
if (rdx != null)
{
user = new UserDomain()
{
email_address = rdx.email_address,
name = rdx.rdx_contact_name,
password = rdx.sdf_rdx_001,
rdx_auto_key = rdx.rdx_auto_key,
settings = _userSettingsDA.Get().Where(x => x.rdx_auto_key == rdx.rdx_auto_key).SingleOrDefault() ?? null
};
}
return user;
}
private RolodexDomain GetRolodexForUser(string email_address)
{
var result = (_rolodexDA.Get().Where(u => u.email_address.ToUpper() == email_address.ToUpper() && u.cv_udf_030.ToUpper() == "T"));
return result.SingleOrDefault() ?? null;
}
问题在于调用导致服务层上的 GetRolodexForUser。当我尝试检查该值时，它会获取未设置为对象实例的对象。
现在理论上应该返回一个空集合？
这是我对这个类的测试中唯一一个在重构后失败的测试，但我不知道为什么:(
有任何想法吗？谢谢！
PS这是我第一次尝试拆开我的应用程序并尝试使其可测试。所以我可能对模拟或依赖注入有一些我不理解的基本问题。
