An alternative test engine for the JUnit 5 platform that focuses on Property-Based Testing.

This repository is a fork of the upstream jqwik project. It exists to keep jqwik usable without upstream's anti-AI runtime prompt behavior.

In May 2026, upstream jqwik added code that printed instruction-like anti-AI text to stdout during test execution, along with a configuration option that could hide that text in terminal emulators while leaving it visible in captured logs and tool output. This fork removes that behavior and the related documentation/configuration surface.

Why this matters: jqwik output is consumed by developers, CI systems, IDEs, logs, and automation. A test library should report test results, not inject unrelated instructions or policy text into downstream execution output.

This fork is active and accepting issues, discussions, bug reports, compatibility reports, and ideas. Use this repository's Issues for concrete bugs or tasks, and Discussions for design questions, feature ideas, and broader project direction.
