In my UserValidation class I am testing a method which that method is internally calling another method. But I just want to return some fake value for that internal method and move on! But the problem is that it is still actually going inside that method.
The method I want to just give me a mock result is this:
public virtual List<Web_Pharmacy_Users> QueryUsersByEmail(string emailAddress)
{
var query = (from u in _cactusDbContext.Web_Pharmacy_Users
where
(u.Email.Trim().ToUpper() == emailAddress.Trim().ToUpper()
&& u.Active)
select u);
return query.ToList();
}
where _cactusDbContext is coming through dependency injection and Web_Pharmacy_Users is a DbSet table.
The way I tried to mock its result is like this below:
ICactusDbContext fakeDbContext = NSubstitute.Substitute.For<ICactusDbContext>();
var partiallyFaked = Substitute.ForPartsOf<UserValidation>(fakeDbContext);
List<Web_Pharmacy_Users> webUsers = new List<Web_Pharmacy_Users>();
try
{
partiallyFaked.QueryUsersByEmail("a@abc.com").Returns(webUsers);
}
catch (Exception e)
{
var dfgf = e.ToString();
throw;
}
But it throws a null exception because it tries to actually run that method so goes to this part of code in _cactusDbContext.Web_Pharmacy_Users and it is null.
I thought it shouldn't even try to go inside and run the actual code. What am I doing wrong?
