Day 32: Integration Testing - Building Bulletproof API Connections
Video:
What We're Building Today
Today we're constructing an integration testing fortress around our Quiz Platform's API layer. Think of it as quality gates that verify every handshake between your components actually works in the wild—not just in isolation.
Key Deliverables:
Integration test suite covering API endpoints
Database integration verification
External service testing (Gemini AI)
Automated CI/CD test pipeline
Real-time test reporting dashboard
The Integration Testing Reality
Integration testing sits in that critical space between "my code works" and "my system works." While unit tests validate individual functions, integration tests verify that when Service A talks to Service B through Database C, magic actually happens instead of chaos.
In production systems like Netflix or Spotify, integration failures cause more outages than individual component bugs. A quiz generation service might work perfectly, but fail when the AI service returns unexpected response formats.
