Look inside

You’re a TypeScript developer for a large company that sells stock photography. You’re responsible for the service that ingests images, and a recent database change has broken the service, despite successful unit testing. Working in IntelliJ WebStorm, you’ll build an integration test that replicates the problem, find the cause, fix the problem, and build the infrastructure to develop more integration tests in the future.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
