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

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"

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 #

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);
  });
});
