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 When you’re done, you’ll have an alarm system that warns you when the assumptions your unit tests rely on are no longer valid, preventing problems in the future.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.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

TOOLS
  • JUnit5
  • Spring
  • Maven
  • Hibernate
TECHNIQUES
  • Working knowledge of Java 11
  • Working knowledge of object-oriented programming

you will learn

In this liveProject, you’ll learn to build a layer of integration tests that replicates an otherwise unreproducible problem and also tests assumptions that your unit tests rely on, creating an alarm system that warns you when those assumptions are no longer valid.

  • Use IntelliJ IDEA to write and execute tests
  • Reproduce problems in hard-to-reach parts of a system with tests
  • Use tests to drive bug fixes
  • Use Hibernate and an in-memory database to inspect the results of service execution
