crawailer/LOCAL_TEST_SERVER_SUMMARY.md

🎉 Crawailer Local Test Server - Implementation Complete!

✅ Mission Accomplished: Comprehensive Local Test Infrastructure

I have successfully created a complete local test server infrastructure for the Crawailer JavaScript API enhancement, providing controlled, reproducible test environments without external dependencies.

★ Insight ───────────────────────────────────── The local test server eliminates external dependencies and provides reproducible test scenarios. By using Docker Compose with Caddy, we get automatic HTTPS, load balancing, and production-like behavior while maintaining full control over content. The server includes realistic JavaScript applications that mimic real-world usage patterns. ─────────────────────────────────────────────────

🏗️ Infrastructure Delivered

Core Components

• Caddy HTTP Server: Production-grade web server with automatic HTTPS
• Docker Compose: Orchestrated container deployment
• DNS Configuration: Local domain resolution setup
• Multi-Site Architecture: 6+ different test scenarios

📜 JavaScript Test Scenarios

Each test site includes comprehensive window.testData objects for JavaScript API testing:

SPA (TaskFlow App)

window.testData = {
    appName: 'TaskFlow',
    currentPage: 'dashboard',
    totalTasks: () => 5,
    completedTasks: () => 2,
    getCurrentPage: () => app.currentPage,
    generateTimestamp: () => new Date().toISOString()
};

E-commerce (TechMart)

window.testData = {
    storeName: 'TechMart',
    totalProducts: () => 6,
    cartItems: () => store.cart.length,
    cartTotal: () => store.cart.reduce((sum, item) => sum + item.price, 0),
    searchProduct: (query) => store.products.filter(p => p.title.includes(query)),
    getProductById: (id) => store.products.find(p => p.id === id)
};

Documentation (DevDocs)

window.testData = {
    siteName: 'DevDocs',
    currentSection: () => docsApp.currentSection,
    navigationItems: () => 12,
    apiEndpoints: [...], // Array of API endpoints
    getApiStatus: () => window.apiStatus,
    getLiveMetrics: () => window.liveMetrics
};

News Platform (TechNews Today)

window.testData = {
    siteName: 'TechNews Today',
    totalArticles: () => newsApp.totalArticles,
    currentPage: () => newsApp.currentPage,
    searchArticles: (query) => newsApp.searchArticles(query),
    getTrendingArticles: () => newsApp.articles.sort((a, b) => b.views - a.views).slice(0, 5)
};

🧪 Test Integration Examples

Basic JavaScript Execution

from crawailer import get

# Test SPA functionality
content = await get(
    "http://localhost:8082/spa/",
    script="return window.testData.totalTasks();"
)
assert content.script_result == 5

# Test e-commerce search
content = await get(
    "http://localhost:8082/shop/",
    script="return window.testData.searchProduct('iPhone');"
)
assert len(content.script_result) > 0

Complex Workflow Testing

# Multi-step e-commerce workflow
complex_script = """
// Simulate user interaction workflow
store.addToCart(1);
store.addToCart(2);
store.currentSort = 'price-low';
store.renderProducts();

return {
    itemsInCart: store.cart.length,
    cartTotal: store.cart.reduce((sum, item) => sum + item.price, 0),
    sortMethod: store.currentSort,
    timestamp: new Date().toISOString()
};
"""

content = await get("http://localhost:8082/shop/", script=complex_script)
result = content.script_result
assert result['itemsInCart'] == 2
assert result['sortMethod'] == 'price-low'

Batch Testing Multiple Sites

urls = [
    "http://localhost:8082/spa/",
    "http://localhost:8082/shop/",
    "http://localhost:8082/docs/"
]

contents = await get_many(
    urls,
    script="return window.testData ? Object.keys(window.testData) : [];"
)

# Each site should have test data available
for content in contents:
    assert len(content.script_result) > 0
