Quality Assurance

ClaudeAutoPM enforces strict quality standards through automated checks, pre-commit hooks, and comprehensive validation processes. This page outlines the quality assurance framework and best practices.

Quality Philosophy

"Quality is not an afterthought - it's built into every step of the development process."

Core Principles

  1. Prevention over Detection: Catch issues before they reach production
  2. Automation First: Automate quality checks wherever possible
  3. Fast Feedback: Provide immediate feedback to developers
  4. Comprehensive Coverage: Test at multiple levels
  5. Continuous Improvement: Learn from issues and improve processes

Definition of Done

Before any code is considered complete, it must meet all criteria:

Code Quality

  • Code follows established patterns and conventions
  • No linting errors or warnings
  • TypeScript strict mode compliance (if applicable)
  • No security vulnerabilities detected
  • Performance impact assessed

Testing Requirements

  • Unit tests written and passing (80% coverage minimum)
  • Integration tests cover main flows
  • E2E tests for critical paths
  • Security tests pass
  • Performance tests meet benchmarks

Documentation

  • Code is self-documenting with clear names
  • Complex logic has inline comments
  • API changes documented
  • README updated if needed
  • Changelog updated for user-facing changes

Review Process

  • Code review completed by team member
  • All feedback addressed
  • Security review if touching sensitive areas
  • Performance review for critical paths

Deployment Readiness

  • All CI/CD checks pass
  • Docker builds successfully
  • Kubernetes deployment tested (if applicable)
  • Rollback plan documented
  • Monitoring alerts configured

Pre-Commit Quality Gates

Git Hooks

ClaudeAutoPM installs comprehensive git hooks to enforce quality:

#!/bin/bash
# .git/hooks/pre-commit

echo "🔒 Running pre-commit validation..."

# Critical files check
echo "📁 Checking critical files..."
required_files=(
  ".claude/strategies/ACTIVE_STRATEGY.md"
  ".claude/base.md"
  "package.json"
)

for file in "${required_files[@]}"; do
  if [[ -f "$file" ]]; then
    echo "  ✓ Found: $file"
  else
    echo "  ❌ Missing required file: $file"
    exit 1
  fi
done

# Run tests
echo "🧪 Running regression tests..."
npm run test:regression
if [[ $? -ne 0 ]]; then
  echo "❌ Regression tests failed"
  exit 1
fi

# Check for test modifications
echo "🔍 Checking for test modifications..."
if git diff --cached --name-only | grep -q "test/"; then
  echo "  ⚠️  Test files modified - running full test suite"
  npm test
  if [[ $? -ne 0 ]]; then
    echo "❌ Tests failed"
    exit 1
  fi
fi

# JavaScript syntax check
echo "🔧 Checking JavaScript syntax..."
for file in $(git diff --cached --name-only | grep -E '\.(js|ts)$'); do
  if [[ -f "$file" ]]; then
    node -c "$file"
    if [[ $? -ne 0 ]]; then
      echo "❌ Syntax error in $file"
      exit 1
    fi
  fi
done

# JSON validation
echo "📋 Checking JSON files..."
for file in $(git diff --cached --name-only | grep -E '\.json$'); do
  if [[ -f "$file" ]]; then
    jq empty "$file" 2>/dev/null
    if [[ $? -ne 0 ]]; then
      echo "❌ Invalid JSON in $file"
      exit 1
    fi
  fi
done

echo "✅ All checks passed! Proceeding with commit."

Safe Commit Script

The safe-commit.sh script provides additional validation:

#!/bin/bash
# scripts/safe-commit.sh

set -e

COMMIT_MSG="$1"

if [[ -z "$COMMIT_MSG" ]]; then
  echo "Usage: ./scripts/safe-commit.sh 'commit message'"
  exit 1
fi

echo "🔒 Running pre-commit validation..."

# Stage all changes
git add .

# Run pre-commit hooks
git commit -m "$COMMIT_MSG"

echo "✅ Commit successful with safety checks"

Code Quality Standards

Linting Configuration

JavaScript/TypeScript (ESLint):

{
  "extends": [
    "@typescript-eslint/recommended",
    "prettier"
  ],
  "rules": {
    "@typescript-eslint/no-unused-vars": "error",
    "@typescript-eslint/explicit-function-return-type": "warn",
    "prefer-const": "error",
    "no-var": "error"
  }
}

Markdown (markdownlint):

{
  "default": true,
  "MD013": false,
  "MD033": {
    "allowed_elements": ["details", "summary"]

}

Code Formatting

Prettier Configuration:

{
  "semi": true,
  "trailingComma": "es5",
  "singleQuote": true,
  "printWidth": 80,
  "tabWidth": 2
}

Security Standards

Security Scanning:

  • npm audit for dependency vulnerabilities
  • CodeQL for code analysis
  • OWASP security checks
  • Secret detection in commits
# Run security checks
npm audit --audit-level=moderate
npm run test:security

Automated Quality Checks

Continuous Integration

Every push triggers comprehensive quality checks:

# Quality gate workflow

Test Quality Standards

Good Test Characteristics:

  • Fast: Unit tests run in milliseconds
  • Independent: No dependencies between tests
  • Repeatable: Same result every time
  • Self-validating: Clear pass/fail
  • Timely: Written close to production code

Test Naming Convention:

describe('UserService', () => {
  describe('createUser', () => {
    it('should create user with valid data', () => {
      // Test implementation
    });

    it('should throw error when email already exists', () => {
      // Test implementation
    });

    it('should sanitize input data', () => {
      // Test implementation
    });
  });
});

Performance Standards

Performance Budgets

Operation Target Maximum
Page load <1s <3s
API response <200ms <500ms
Database query <50ms <100ms
Test suite <30s <60s
Docker build <2min <5min

Performance Monitoring

// Performance test example
describe('Performance Tests', () => {
  it('should handle 100 concurrent users', async () => {
    const startTime = Date.now();

    const requests = Array(100).fill().map(() =>
      request(app).get('/api/users')
    );

    const responses = await Promise.all(requests);
    const duration = Date.now() - startTime;

    expect(duration).toBeLessThan(5000); // 5 seconds max
    expect(responses.every(r => r.status === 200)).toBe(true);
  });
});

      .post('/api/search')
      .send({ query: maliciousInput });

    expect(response.status).toBe(400);
    expect(response.body.error).toMatch(/invalid input/i);
  });

  it('should sanitize XSS attempts', async () => {
    const xssPayload = '<script>alert("XSS")</script>';
    const response = await request(app)
      .post('/api/comments')
      .send({ content: xssPayload });
