pytest integration test suite
Python
A full integration test suite for a Django API using pytest, factory_boy fixtures and a real PostgreSQL test database.
Stopped a class of bugs that had previously only surfaced in staging.
Problem
The service had only unit tests; integration bugs repeatedly reached staging because mocked tests did not catch contract violations.
Solution
Wrote integration tests using pytest-django and factory_boy, spun up a dedicated test DB in CI, and blocked merges below 80% coverage.
