Custom Data-annotation not firing in unit-test - unit-testing

Question

I am currently experimenting with validation attributes,
and now I am trying to validate my ViewModel which contains an EmailAddress with a custom validation attribute.
public class UserLoginModel
{
[Required]
[EmailAddress]
public string email { get; set; }
[Required]
public string password { get; set; }
public bool rememberMe { get; set; }
}
I have made a unit-test where I give a false email address and try to validate my viewmodel.
[TestMethod]
public void TestingInvalidEmailAddress()
{
UserLoginModel model = new UserLoginModel();
model = GetAValidLoginModel(); //Get a default-model where all parameters are correct
model.email = "thisisnotavalidemail.com";
ValidationContext context = new ValidationContext(model, null, null);
var results = new List<ValidationResult>();
bool validModel= Validator.TryValidateObject(model, context, results);
//This is always true
Assert.IsFalse(validModel);
}
The result of this test is always False.
So I checked my attribute, because I thought I might have made a mistake:
[TestMethod]
public void Email()
{
string email;
var attr = new EmailAddressAttribute();
email = "myemail#domain.com";
Assert.IsTrue(attr.IsValid(email));
email = "thisisnotavalidemail.com";
Assert.IsFalse(attr.IsValid(email)); //If this fails, the test is successfull
}
And that did pass the test, using the exact same email address.
And when I test it in my browser, it also validates correctly.
So why does it not tell me that my email address is invalid in the first test-method?

I found my solution in over here.
Apparently I am just missing an extra parameter.
bool validModel= Validator.TryValidateObject(model, context, results, **true**);
