SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD rendering gate for Copier template development. Writes E2E assertions first, then iteratively fixes the template until all flavors render cleanly. Never commits on a red suite. Use when editing Copier template files (copier.yml, .jinja files, flavor overlays). NOT for non-template projects, runtime code changes, or general testing (use /validate).

Core Features & Use Cases

  • End-to-end rendering validation driven by test-driven development loops for Copier templates.
  • Iterative fixes until all flavors render correctly, preventing commits on failures.
  • Guardrails that ensure only template-related changes affect rendering results.

Quick Start

Run the render-gate workflow to validate that all Copier template flavors render cleanly and iteratively fix the template until all tests pass.

FAQPage Schema
How do I automate Copier template rendering validation before commits?

End-to-end rendering validation for Copier templates works by creating E2E assertions first, validating all flavor outputs across environments, and blocking commits until the test suite turns green.

How do I apply TDD to Copier template development with multiple flavors?

TDD for Copier templates involves creating E2E assertions for all flavors upfront, then iteratively editing copier.yml or .jinja files until every flavor renders cleanly without failures.

Can I use a rendering gate to prevent commits on broken Copier template overlays?

Yes, a rendering gate enforces a deterministic commit block when Copier template flavor overlays fail E2E validation, ensuring only passing template changes are committed.

What is the best way to validate Copier template flavors across different environments?

The best way to validate Copier template flavors across environments is driving TDD-style E2E checks that assert rendering outputs deterministically before allowing any template commit.

When should I not use an automated rendering gate for template testing?

You should not use an automated rendering gate for non-template projects, runtime code changes, or general testing, as it specifically validates Copier template flavor rendering and blocks commits.
