Test your tests

Summary: test interfaces, not implementations

Tests that pass when something is actually broken, and fail when things actually do work, are worse than useless- they are positively harmful.

The requirement

Let's say we've been tasked with returning 400 when GET /users/<userId> is called with a negative userId.

The test

The requirement can be turned into a test that hits the endpoint with a negative userId and checks that a 400 is returned:
