PR-Proof-of-Workv1.0.0

A developer identifies an open issue in a web application, writes a Playwright E2E test that captures a 'before' screenshot showing the bug, implements the fix, and captures an 'after' screenshot. The PR includes a side-by-side comparison, providing undeniable visual evidence of the fix.

When adding a new feature, the developer first writes an E2E test that defines the expected behavior, then implements the feature until the test passes. Screenshots document the initial state and the final working feature, ensuring the implementation meets requirements.

A team sets up automated E2E tests that run on every PR, capturing screenshots at key states. Any visual regression is immediately visible in the PR comments, allowing reviewers to catch unintended changes quickly.

For a backend change that affects UI indirectly (e.g., a new API endpoint, configuration change), the developer writes an E2E test that exercises the related UI path (e.g., opening settings, running a terminal command) and captures screenshots to demonstrate the change works correctly end-to-end.

Open-source projects use this workflow to guide new contributors: pick an issue, write a test, fix, and submit a PR with screenshots. The structured process ensures contributions are testable and visually verifiable.

Offer a basic version of the TDD-E2E-PR workflow as a CLI tool or GitHub Action for free, with premium features like advanced analytics, team dashboards, and priority support via a subscription.

Provide consulting to integrate this workflow into client development pipelines, along with training workshops on TDD, Playwright, and CI/CD best practices.

Build a cloud platform that hosts E2E test runs, stores screenshots, and provides a visual diff review interface. Integrate with GitHub to automatically post screenshot comparisons.
