Workshop: Introduction to Testing in Python
summary
Workshop builds a credit card validator, fixes real bugs and adds unit tests that actually assert behavior rather than restating the topic, using pytest for discovery and parameterization, unittest.mock and requests‑mock to avoid network flakiness, and coverage.py to report which lines never run. The code is refactored to separate input/output from logic so tests are deterministic, tests catch issuer and length errors, and mocked API responses let API‑dependent checks run reliably.
