regression-test-generator

Regression tests capture bug details and reproduction steps, then generate Arrange-Act-Assert formatted tests automatically. This Skill detects your installed test framework—Jest, Vitest, pytest, or Playwright—collects bug information, creates test files under tests/regression/, and links them to your error log for future reference and bug prevention.

Yes. Regression test generation works across Jest, Vitest, pytest, and Playwright by auto-detecting your project's test framework and generating framework-appropriate Arrange-Act-Assert templates that follow your project's patterns and naming conventions.

Provide bug details including the reproduction steps, expected behavior, and actual behavior. The Skill uses this information to generate a complete test that verifies the fix, references the error ID, and saves it to tests/regression/ with a link to error-log.md.

Regression tests are saved under tests/regression/ and automatically linked to error-log.md. This organization maintains traceability between test files, bug reports, and error IDs while adhering to your project's file placement and naming conventions.

Regression test generation automates test creation by collecting bug details, detecting your test framework, and generating complete Arrange-Act-Assert tests. You review the generated test and can save or edit it as needed before committing.

Linking regression tests to error logs and bug IDs creates a complete audit trail. This ensures each test documents which bug it prevents, making it easier to understand test intent, maintain test coverage as bugs are fixed, and prevent regression when similar issues recur.
