test metod
private MvcProjectContext _context;
private IUnitOfWork _uow;
private IUserService _userService;
[TestInitialize]
public void TestInitialize()
{
_context = new MvcProjectContext();
_uow = new UnitOfWork(_context);
_userService = new UserService(_uow);
}
[TestMethod]
public void TestMethodAddUser()
{
_userService.Insert(new User
{
DisplayName = "test display name",
Email = "test_email@mail.com",
LanguageId = 1,
LastLoginDate = DateTime.Now,
LastLoginIp = "192.168.1.1",
Password = "12345",
ProfileImageUrl = "profile image",
UserName = "test_user"
});
Assert.AreEqual(1,_uow.SaveChanges());
}
I debugged it and checked it, user is adding dbcontext, but when
savechanges method firing, I get error
"invalid column name 'LanguageId'"
I cant find any solution. In DB there is column that named 'LanguageId'.
it does not seem to be something missing. Any advice?
