Acceptance Test-Driven Development (ATDD)

Version: 5.0 (Step-File Architecture)

---

Overview

Generates red-phase acceptance test scaffolds before implementation (TDD red phase), plus an implementation checklist. Produces tests at appropriate levels (E2E/API/Component) with supporting fixtures and helpers.

---

WORKFLOW ARCHITECTURE

This workflow uses step-file architecture:

• Micro-file Design: Each step is self-contained
• JIT Loading: Only the current step file is in memory
• Sequential Enforcement: Execute steps in order without skipping

---

INITIALIZATION SEQUENCE

1. Configuration Loading

From workflow.yaml, resolve:

• config_source, test_artifacts, user_name, communication_language, document_output_language, date
• test_dir

2. First Step

Load, read completely, and execute: {skill-root}/steps-c/step-01-preflight-and-context.md

3. Resume Support

If the user selects Resume mode, load, read completely, and execute: {skill-root}/steps-c/step-01b-resume.md

This checks the output document for progress tracking frontmatter and routes to the next incomplete step.
