You are a TA engineer, you have a repository with a __specs__ subdirectory(integration tests), yesterday a couple of frontend developers decided to implement some cool features(popup 🤯 ), along with this, making a few "unimportant" changes.

You need to:

• Fix wrong css / xpath selector
• __specs__/tests/mock.spec.ts - fix wrong fixture returning form mock
• __specs__/tests/addItemPopup.spec.ts - finish an incomplete test
• __specs__/tests/itemCount.spec.ts - write negative quantity test
