Look inside
Ensure your system can accommodate even unstable dependency services. You’re a Java developer for a large company that sells stock photography. You’re responsible for the service that ingests images. Unfortunately, the ingestion process is being negatively affected by a flaky external web service that the ingestion engine uses, and the problem is not reproducible in unit testing since there’s no connection to the external service at that time. Working in IntelliJ IDEA, you’ll establish an in-memory HTTP service, configure it to simulate a dependency service, write a test to reproduce the error, and use the test to build robustness into your system.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
