How do I pass this test then?
Don't do what she asks.
The test is to see if you'll do what she asks. If you do, then you're beta, and she'll know to look elsewhere for an alpha. If you make up your own mind and do what you think is right, not what she asks, then she confirms that you're alpha and it's ok to keep sleeping with you.
A sh*t test can also take the form of a statement. She could say your haircut looks funny. If you agree with her and ask her to how to make it better, then you're beta. If you reply that you like your hair the way it is, then you're alpha.
All women do this to men for their entire lives because their biggest existential fear is to sleep with a beta when they could be with an alpha. They can never admit to sh*t testing men or tell them how to be alpha because then it wouldn't count.
Of course, you'd be a complete *sshole if you never tried to make her happy, she just wants you to decide on your own to make her happy. She doesn't want to have to ask you to do it.
In spite of everything that feminism tells them, women still secretly want men to be in charge of relationships. Their social conditioning just makes that even harder to admit these days.
