🧪 Testing Demo: From API Contracts to End-to-End
A complete testing strategy validates the system at multiple levels:
🔵 API Contract Testing
REST endpoints are tested with positive and negative scenarios — JWT errors, invalid pagination, malformed JSON, security payloads, and role-based access.
🟢 Analytics Functional Testing
Mathematical correctness is validated through OEE, MTBF, bottleneck calculations, aggregation consistency, ETL flow, and KPI invariants.
🟠 Playwright End-to-End Testing
Real browser workflows validate:
- 🔁 Duplicate data does not increase counters
- 📦 Batch processing updates production/data counts
- ⚡ Streaming events increase event counters
🔺 One Test Pyramid. Three Levels.
Analytics proves the numbers.
API testing proves the contract.
Playwright proves the complete user journey.
🚀 Together, they provide confidence that the system is correct, reliable, and working end-to-end.
