SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate regression tests automatically when bugs are discovered in /debug or during continuous checks. Auto-detects test frameworks, creates Arrange-Act-Assert tests, and links to error-log.md entries for traceability.

Core Features & Use Cases

  • Auto-detects the active test framework (Jest, Vitest, pytest, Playwright) and generates framework-aligned regression tests.
  • Produces Arrange-Act-Assert style test files that reproduce bugs and verify fixes.
  • Links tests to error-log.md entries to ensure traceability across bugs and documentation.

Quick Start

Provide bug details and run the generator to produce a regression test.

FAQPage Schema
How do I auto-generate regression tests to prevent bug recurrence?

To auto-generate regression tests, provide bug details to the generator. It produces Arrange-Act-Assert style tests that reproduce bugs, verify fixes, and save the regression file in the project's tests/regression directory.

Does this regression test generator work with Jest and Playwright?

Yes, the regression test generator works with Jest, Vitest, pytest, and Playwright. It auto-detects the active project test framework and generates framework-aligned tests to ensure compatibility.

What is the Arrange-Act-Assert structure for regression testing?

The Arrange-Act-Assert structure is a testing pattern where you set up conditions, execute the behavior, and verify outcomes. The generator produces regression tests using this structure to reproduce bugs and verify fixes.

How do I link regression tests to error logs for traceability?

To link regression tests to error logs, the generator updates error-log.md entries automatically. Generated tests reference these logs to document the bug rationale and ensure traceability across documentation.

Where are generated regression test files saved in my project?

Generated regression test files are saved in the project's tests/regression directory. The generator creates the file in this specific location to maintain a consistent structure for regression testing artifacts.
