Java unit tests that stay fast and predictable.
Guides the writing, review, and repair of deterministic Java unit tests while preserving project conventions.
When to use it
Use when adding, refactoring, or debugging tests in Maven or Gradle projects.
It changes how the agent writes, reviews, and fixes Java unit tests, following the project's existing testing conventions.
What you provide

Requires a Java runtime compatible with the project's JUnit version: Java 8 for JUnit 5 or Java 17 for JUnit 6.
The guidance is for JUnit Jupiter, using the project's detected JUnit version rather than implicitly upgrading it.
