Microservices Architecture in Node.js - Automated Testing

on YouTube ↗41m

" summary

Adds live scooter location to a Node.js microservice, first stored in a DB, later moved to Redis and then extracted into a separate live-location service; unit tests (Jest, Mocha, Jasmine, Chai) mock internals and kept passing while a bug (sending state in request body instead of query string) slips into production. Recommends API tests for tolerance to implementation changes, integration tests to catch inter-service contract mismatches, CI/CD that runs unit/api/integration on push, plus canary, synthetic user testing, and fault injection in production.
