Test Centralization Summary

All tests have been centralized into the tests/ directory following standard testing conventions.

📁 New Test Structure

tests/
├── run-tests.php           # Main test runner
├── README.md               # Test documentation
├── Unit/                   # Unit tests
│   ├── DatabaseTest.php    # Database connection & queries
│   └── RateLimitTest.php   # Rate limiting functionality
├── Integration/            # Integration tests
│   └── SearchTest.php      # Search functionality
└── Security/               # Security tests
    └── SecurityTest.php    # SQL injection & XSS protection

✅ What Was Done

1. Created Test Directory Structure

• tests/Unit/ - Tests for individual components
• tests/Integration/ - Tests for feature workflows
• tests/Security/ - Tests for security vulnerabilities

2. Moved & Created Tests

Before:

• test_db.php (root) - Basic database test
• run-tests.php (root) - Old test runner

After:

• tests/Unit/DatabaseTest.php - Comprehensive database testing
• tests/Unit/RateLimitTest.php - Rate limit testing
• tests/Integration/SearchTest.php - Search functionality testing
• tests/Security/SecurityTest.php - Security testing
• tests/run-tests.php - New unified test runner
• tests/README.md - Complete test documentation

3. Updated Justfile

New Commands:

just test              # Run all tests
just test-unit         # Run unit tests only
just test-integration  # Run integration tests only
just test-security     # Run security tests only
just syntax            # Check PHP syntax

Removed:

• Old scattered test commands
• Duplicate test logic

4. Removed Old Files

• ✅ Deleted test_db.php from root
• ✅ Deleted run-tests.php from root

🎯 Benefits

Before Centralization

• ❌ Tests scattered in root directory
• ❌ No clear organization
• ❌ Hard to run specific test types
• ❌ No test documentation
• ❌ Inconsistent test format

After Centralization

• ✅ All tests in tests/ directory
• ✅ Clear organization (Unit/Integration/Security)
• ✅ Easy to run any combination
• ✅ Comprehensive test documentation
• ✅ Consistent test format and output
• ✅ Single test runner
• ✅ Beautiful formatted output

📚 Writing New Tests

1. Choose Test Type

• Unit Test → tests/Unit/ - Tests single functions/classes
• Integration Test → tests/Integration/ - Tests feature workflows
• Security Test → tests/Security/ - Tests security measures

2. Use Template

<?php
/**
 * Test Name
 * Description
 */

require_once __DIR__ . '/../../lib/YourClass.php';

echo "Test Name\n";
echo "=========\n\n";

try {
    echo "Test 1: Description\n";
    // ... test code ...
    echo "✓ PASS: Test passed\n\n";

    echo "✅ All tests passed!\n";
    return true;

} catch (Exception $e) {
    echo "❌ FAIL: " . $e->getMessage() . "\n";
    return false;
}

3. Add to Test Runner

Edit tests/run-tests.php and add your test to the $testFiles array:

['name' => 'Your Test Name', 'path' => __DIR__ . '/Unit/YourTest.php'],

4. Run It

just test

🔄 CI/CD Integration (Future)

Tests are ready for CI/CD integration:

# .github/workflows/test.yml
name: Tests
on: [push, pull_request]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: '8.4'
      - name: Run tests
        run: php tests/run-tests.php
