Look inside
Create an alarm system that warns you before your system breaks. You’re a Java developer for a large company that sells stock photography. You’re responsible for the service that ingests images. A recent upgrade to the image scaling library has caused a problem with the aspect ratio of thumbnail images. Working in IntelliJ IDEA, you’ll build a layer of integration tests that replicates the problem and also tests assumptions that your unit tests rely on. When you’re done, you’ll have an alarm system that warns you when the assumptions your unit tests rely on are no longer valid, preventing problems in the future.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
