Property-Based Testing with `test.check` helps Java engineers practice the Clojure design, tooling, and review choices needed to use this topic in production JVM code.
Property-Based Testing with test.check focuses the intermediate track on decisions a Java engineer must make after the first syntax barrier is gone. Read these lessons as engineering checkpoints: what data shape is being moved, which boundary is stateful, and where Clojure should simplify rather than imitate the Java design.
| Checkpoint | Use it to verify |
|---|---|
| Concept fit | You can explain where test.check changes the design compared with an object-oriented Java version. |
| Implementation shape | You can sketch the Clojure namespace, data flow, and JVM boundary before writing code. |
| Review risk | You can name the main failure mode: hidden mutation, unclear dependencies, over-clever macros, weak tests, or operational blind spots. |
