Voter and unit test. Mistake?

Question

symfony

I have a voter that works great, but the problem is that I still have unit tests (php unittest) and this is where I got the error.
The scheme is as follows: the controller selector checks whether the $user object belongs to the User entity, if yes - the program goes further, if not - false.

if (!$user instanceof User) {
            return false;
        }

My test object is related to the InMemoryUser test entity so the test fails.
Tell me, please, how to fix the situation?

Answer 1

Use mocks and stubs for test doubles. Submit the desired object and check the condition.

Answer 2

Make the link block, set the desired size, background, etc.
For an icon in a button, you need to put the i tag in the link, make it block, put the background.
And the text can simply be left as text.

Answer 3

Isn't it easier to install a firebug and stupidly look at how it's done on the site?
