Test Documentation Creator

This skill creates and validates test documentation: testing-strategy.md (universal testing philosophy) + tests/README.md (test organization structure and Story-Level Test Task Pattern).

Purpose

Creates and validates test documentation (testing-strategy.md + tests/README.md) establishing universal testing philosophy, Risk-Based Testing strategy, and Story-Level Test Task Pattern for any project.

When to Use This Skill

This skill is a L2 WORKER invoked by ln-100-documents-pipeline orchestrator.

This skill should be used directly when:

  • Creating only test documentation (testing-strategy.md + tests/README.md)
  • Validating existing test documentation structure and content
  • Setting up test philosophy and structure documentation for existing project
  • NOT creating full documentation structure (use ln-100-documents-pipeline for complete setup)

Workflow

The skill follows a 3-phase workflow: CREATE → VALIDATE STRUCTURE → VALIDATE CONTENT. Each phase builds on the previous, ensuring complete structure and semantic validation.

Phase 1: Create Test Documentation

Objective: Establish test philosophy and documentation structure.

Process:

1.1 Check & create directories:

  • Check if docs/reference/guides/ exists → create if missing
  • Check if tests/ exists → create if missing
  • Check if tests/manual/ exists → create if missing
  • Check if tests/manual/results/ exists → create if missing
  • Add tests/manual/results/ to project .gitignore if not present
  • Log for each: "✓ Created [directory]/" or "✓ [directory]/ already exists"

1.2 Check & create documentation files:

  • Check if docs/reference/guides/testing-strategy.md exists

  • If exists:

    • Skip creation
    • Log: "✓ testing-strategy.md already exists, proceeding to validation"

  • If NOT exists:

    • Copy template: ln-114-test-docs-creator/references/testing_strategy_template.md → docs/reference/guides/testing-strategy.md
    • Replace placeholders:
      • [CURRENT_DATE] — current date (YYYY-MM-DD)
    • Log: "✓ Created testing-strategy.md from template"

  • Check if tests/README.md exists

  • If exists:

    • Skip creation
    • Log: "✓ tests/README.md already exists, proceeding to validation"

  • If NOT exists:

    • Copy template: ln-114-test-docs-creator/references/tests_readme_template.md → tests/README.md
    • Replace placeholders:
      • {{DATE}} — current date (YYYY-MM-DD)
    • Log: "✓ Created tests/README.md from template"

1.3 Output:

docs/reference/guides/
└── testing-strategy.md           # Created or existing

tests/
├── README.md                     # Created or existing
└── manual/
    └── results/                  # Created, added to .gitignore

Phase 2: Validate Structure

Objective: Ensure test documentation files comply with structural requirements and auto-fix violations.

Process:

2.1 Check SCOPE tags:

  • Read both files (testing-strategy.md, tests/README.md) - first 5 lines only
  • Check for <!-- SCOPE: ... --> tag in each
  • Expected SCOPE tags:
    • testing-strategy.md: <!-- SCOPE: Universal testing philosophy (Risk-Based Testing, test pyramid, isolation patterns) -->
    • tests/README.md: <!-- SCOPE: Test organization structure (directory layout, Story-Level Test Task Pattern) -->
  • If missing in either file:
    • Use Edit tool to add SCOPE tag at line 1 (before first heading)
    • Track violation: scope_tags_added += 1

2.2 Check required sections:

  • Load expected sections from references/questions.md
  • For testing-strategy.md, required sections:
    • "Testing Philosophy"
    • "Test Levels"
  • For tests/README.md, required sections:
    • "Test Organization"
    • "Running Tests"
  • For each file:
    • Read file content
    • Check if ## [Section Name] header exists
    • If missing:
      • Use Edit tool to add section with placeholder content from template
      • Track violation: missing_sections += 1

2.3 Check Maintenance section:

  • For each file (testing-strategy.md, tests/README.md):
    • Search for ## Maintenance header
    • If missing:
      • Use Edit tool to add at end of file: 
        ## Maintenance

**Last Updated:** [current date]

**Update Triggers:**
- Test framework changes
- Test organization changes
- New test patterns introduced

**Verification:**
- [ ] All test examples follow current framework syntax
- [ ] Directory structure matches actual tests/
- [ ] Test runner commands are current
      • Track violation: maintenance_added += 1

2.4 Check POSIX file endings:

  • For each file:
    • Check if file ends with single blank line (LF)
    • If missing:
      • Use Edit tool to add final newline
      • Track fix: posix_fixed += 1

2.5 Report validation:

  • Log summary: 
    ✅ Structure validation complete:
  - SCOPE tags: [added N / already present]
  - Missing sections: [added N sections]
  - Maintenance sections: [added N / already present]
  - POSIX endings: [fixed N / compliant]
  • If violations found: "⚠️ Auto-fixed [total] structural violations"

Phase 3: Validate Content

Objective: Ensure each section answers its questions with meaningful content and populate test-specific sections from auto-discovery.

Process:

3.1 Load validation spec:

  • Read references/questions.md
  • Parse questions and validation heuristics for 4 sections (2 per file)

3.2 Validate testing-strategy.md sections:

For this file, use standard template content (no auto-discovery needed):

  1. Testing Philosophy section:

    • Read section content
    • Check validation heuristics from questions.md:
      • ✅ Mentions "Risk-Based Testing"
      • ✅ Has test pyramid description
      • ✅ Mentions priority threshold (≥15)
      • ✅ References Story-Level Test Task Pattern
      • ✅ Length > 100 words
    • If ANY heuristic passes → content valid
    • If ALL fail → log warning: "⚠️ testing-strategy.md → Testing Philosophy section may need review"

  2. Test Levels section:

    • Read section content
    • Check validation heuristics from questions.md:
      • ✅ Lists 3 levels (E2E, Integration, Unit)
      • ✅ Has numeric ranges (2-5, 3-8, 5-15)
      • ✅ Explains rationale
      • ✅ Length > 150 words
    • If ANY heuristic passes → content valid
    • If ALL fail → log warning: "⚠️ testing-strategy.md → Test Levels section may need review"

Note: testing-strategy.md is universal philosophy - no project-specific auto-discovery needed.

3.3 Validate tests/README.md sections with auto-discovery:

Section: Test Organization

  1. Auto-discover test framework:

    • Check package.json → "devDependencies" and "dependencies":
      • Node.js frameworks: jest, vitest, mocha, ava, tap, jasmine
      • If found: Extract name and version
    • Check requirements.txt (if Python project):
      • Python frameworks: pytest, nose2, unittest2
      • If found: Extract name and version
    • Check go.mod (if Go project):
      • Go uses built-in testing package
    • If framework detected:
      • Log: "✓ Test framework detected: [framework]@[version]"
      • Track: framework_detected = "[framework]"
    • If NOT detected:
      • Log: "⚠️ No test framework detected. Will use generic test organization."
      • Track: framework_detected = None

  2. Auto-discover test directory structure:

    • Use Glob tool to scan tests/ directory:
      • Pattern: "tests/e2e/**/*.{js,ts,py,go}"
      • Pattern: "tests/integration/**/*.{js,ts,py,go}"
      • Pattern: "tests/unit/**/*.{js,ts,py,go}"
    • Count files in each directory:
      • e2e_count = len(e2e_files)
      • integration_count = len(integration_files)
      • unit_count = len(unit_files)
    • If directories exist:
      • Log: "✓ Test structure: [e2e_count] E2E, [integration_count] Integration, [unit_count] Unit tests"
    • If directories DON'T exist:
      • Create placeholder structure: 
        tests/
  e2e/       (empty, ready for E2E tests)
  integration/  (empty, ready for Integration tests)
  unit/      (empty, ready for Unit tests)
      • Log: "✓ Created test directory structure (will be populated during Story test task execution)"

  3. Auto-discover naming conventions:

    • For each test file found (from step 2):
      • Extract filename pattern:
        • *.test.js → "*.test.js" convention
        • *.spec.ts → "*.spec.ts" convention
        • test_*.py → "test_*.py" convention
        • *_test.go → "*_test.go" convention
    • Count occurrences of each pattern
    • Use most common pattern (majority rule)
    • If pattern detected:
      • Log: "✓ Naming convention: [pattern] (detected from [count] files)"
    • If NO files exist:
      • Use framework default:
        • Jest/Vitest → *.test.js
        • Mocha → *.spec.js
        • Pytest → test_*.py
        • Go → *_test.go
      • Log: "✓ Naming convention: [default_pattern] (framework default)"

  4. Check Test Organization section content:

    • Read section from tests/README.md
    • Check validation heuristics:
      • ✅ Describes directory structure (e2e/integration/unit)
      • ✅ Mentions naming conventions
      • ✅ References Story-Level Test Task Pattern
      • ✅ Has framework mention
    • If ANY heuristic passes → content valid
    • If ALL fail → log warning: "⚠️ tests/README.md → Test Organization section needs update"

Section: Running Tests

  1. Auto-discover test runner command:

    • Read package.json → "scripts" → "test"
    • If found:
      • Extract command value
      • Examples:
        • "jest" → Test runner: "npm test" (runs jest)
        • "vitest" → Test runner: "npm test" (runs vitest)
        • "mocha" → Test runner: "npm test" (runs mocha)
        • Custom script → Test runner: "npm test" (runs [custom])
      • Log: "✓ Test runner: npm test (runs [command])"
    • If NOT found (no package.json or no test script):
      • Use default based on detected framework (from step 3.3.1):
        • Jest → "npm test"
        • Vitest → "npm test"
        • Pytest → "pytest"
        • Go → "go test ./..."
      • Log: "⚠️ No test script found in package.json. Using default '[command]'."

  2. Auto-discover coverage command (optional):

    • Check package.json → "scripts" for:
      • "test:coverage"
      • "coverage"
      • "test:cov"
    • If found:
      • Extract command
      • Log: "✓ Coverage command: npm run [script_name]"
    • If NOT found:
      • Use framework default:
        • Jest → "npm test -- --coverage"
        • Vitest → "npm test -- --coverage"
        • Pytest → "pytest --cov=src"
        • Go → "go test -cover ./..."
      • Log: "✓ Coverage command: [default] (framework default)"

  3. Check Running Tests section content:

    • Read section from tests/README.md
    • Check validation heuristics:
      • ✅ Has test runner command
      • ✅ Mentions coverage
      • ✅ Shows how to run specific tests
      • ✅ Has command examples
    • If ANY heuristic passes → content valid
    • If ALL fail → log warning: "⚠️ tests/README.md → Running Tests section needs update"

3.4 Report content validation:

  • Log summary: 
    ✅ Content validation complete:
  - testing-strategy.md: [2 sections checked]
  - tests/README.md: [2 sections checked]
  - Test framework: [detected framework or "Not detected"]
  - Test structure: [e2e/integration/unit counts or "Created placeholder"]
  - Naming convention: [pattern or "Framework default"]
  - Test runner: [command]
  - Coverage command: [command]

Complete Output Structure

docs/reference/guides/
└── testing-strategy.md           # Universal testing philosophy (465 lines)

Note: Actual test directories (e2e/, integration/, unit/) created during Story test task execution or Phase 3 if missing.

Critical Rules

  • Documentation only: This skill creates test DOCUMENTATION, NOT actual test code
  • 3-phase pipeline: CREATE → VALIDATE STRUCTURE → VALIDATE CONTENT (no phase skipping)
  • Auto-discovery first: Scan test frameworks and directory structure before falling back to defaults
  • Idempotent execution: Checks existence before creation; re-validates on each run without duplication
  • SCOPE tags required: Both files must have <!-- SCOPE: ... --> tag in first 5 lines

Reference Files

  • Risk-based testing methodology: shared/references/risk_based_testing_guide.md

Templates

Testing Strategy Template:

  • references/testing_strategy_template.md - Universal testing philosophy with:
    • SCOPE tags (testing philosophy, NOT framework-specific)
    • Core Philosophy ("Test YOUR code, not frameworks")
    • Risk-Based Testing Strategy (Priority Matrix, test caps)
    • Story-Level Testing Pattern
    • Test Organization (E2E/Integration/Unit definitions)
    • Isolation Patterns (Data Deletion/Transaction Rollback/DB Recreation)
    • What To Test vs NOT Test (universal examples)
    • Testing Patterns (Arrange-Act-Assert, Mock at the Seam, Test Data Builders)
    • Common Issues (Flaky Tests, Slow Tests, Test Coupling)
    • Coverage Guidelines
    • Verification Checklist

Tests README Template:

  • references/tests_readme_template.md - Test organization with:
    • SCOPE tags (test documentation ONLY)
    • Overview (E2E/Integration/Unit test organization)
    • Testing Philosophy (brief, link to testing-strategy.md)
    • Test Structure (directory tree)
    • Story-Level Test Task Pattern (tests in final Story task, NOT scattered)
    • Test Execution (project-specific commands)
    • Quick Navigation (links to testing-strategy.md, kanban_board, guidelines)
    • Maintenance section (Update Triggers, Verification, Last Updated)

Validation Specification:

  • references/questions.md (v1.0.0) - Question-driven validation:
    • Questions each section must answer (4 sections total)
    • Validation heuristics (ANY passes → valid)
    • Auto-discovery hints (test frameworks, directory structure, naming conventions)
    • MCP Ref hints (external research if needed)

Best Practices

  • No premature validation: Phase 1 creates structure, Phase 2 validates it (no duplicate checks)
  • Parametric validation: Phase 3 validates 4 sections across 2 files (no code duplication)
  • Auto-discovery first: Scan test frameworks and directory structure before using defaults
  • Idempotent: ✅ Can run multiple times safely (checks existence before creation, re-validates on each run)
  • Separation of concerns: CREATE → VALIDATE STRUCTURE → VALIDATE CONTENT
  • Story-Level Test Task Pattern: Tests consolidated in final Story task (test planner creates task, test executor implements)
  • Value-Based Testing: 2-5 E2E, 3-8 Integration, 5-15 Unit per Story (10-28 total max), Priority ≥15 MUST be tested
  • No test code: This skill creates DOCUMENTATION only, NOT actual tests

Documentation Standards

  • NO_CODE Rule: Test docs describe strategy, not test implementations
  • Stack Adaptation: Framework commands must match project stack
  • Format Priority: Tables (test levels, counts) > Lists > Text
