There is a category of test that feels productive, passes consistently, and catches absolutely nothing. It lives in most codebases. It gets written during sprints, committed without question, and reviewed without comment. Nobody talks about it because it looks fine.
It is the mocked email test.
What it looks like
jest.mock('../lib/email', () => ({
sendVerificationEmail: jest.fn().mockResolvedValue({ id: 'mock-id' })
