mock
Domain: Testing Quality
🎯 Motivation
A mock is a fake object that simulates the behavior of a real one, like an API or database. Mocking lets you test code in isolation without slow or unreliable external dependencies.
📋 Concrete Example
You replace a payment gateway with a Mock that always returns {"status": "success"}, so your test verifies the order logic without calling a real bank.
🔗 Analogy
A mock is like a crash-test dummy standing in for a real passenger. You can test the car’s safety systems without risking an actual person.
