# API Test Generation

I'll generate comprehensive API tests for your REST or GraphQL endpoints with proper validation and assertions.

**Features:**
- Auto-detect API framework (Express, FastAPI, Next.js API routes)
- Generate request/response tests
- Schema validation
- Error handling tests
- Authentication tests


## Phase 1: API Framework Detection

```bash
# Detect API framework efficiently
detect_api_framework() {
    if [ -f "package.json" ]; then
        if grep -q "\"express\"" package.json; then
            echo "express"
        elif grep -q "\"fastify\"" package.json; then
            echo "fastify"
        elif grep -q "\"next\"" package.json; then
            echo "nextjs"
        elif grep -q "\"@apollo/server\"" package.json; then
            echo "apollo"
        fi
    elif [ -f "requirements.txt" ]; then
        if grep -q "fastapi" requirements.txt; then
            echo "fastapi"
        elif grep -q "flask" requirements.txt; then
            echo "flask"
        elif grep -q "django" requirements.txt; then
            echo "django"
        fi
    elif [ -f "go.mod" ]; then
        if grep -q "gin-gonic" go.mod; then
            echo "gin"
        elif grep -q "fiber" go.mod; then
            echo "fiber"
        fi
    fi
}

FRAMEWORK=$(detect_api_framework)

if [ -z "$FRAMEWORK" ]; then
    echo "❌ No API framework detected"
    echo "Supported frameworks:"
    echo "  Node: Express, Fastify, Next.js API routes, Apollo"
    echo "  Python: FastAPI, Flask, Django"
    echo "  Go: Gin, Fiber"
    exit 1
fi

echo "✓ API Framework: $FRAMEWORK"
```

## Phase 2: Endpoint Discovery

```bash
echo ""
echo "Discovering API endpoints..."

# Use Grep to find endpoints efficiently
case $FRAMEWORK in
    express|fastify)
        ENDPOINTS=$(grep -r "\.get\(\\|\.post\(\\|\.put\(\\|\.delete\(\\|\.patch\(" \
                         --include="*.js" --include="*.ts" \
                         --exclude-dir=node_modules \
                         . | head -20)
        ;;
    nextjs)
        # Next.js API routes are file-based
        ENDPOINTS=$(find pages/api app/api -name "*.ts" -o -name "*.js" 2>/dev/null | head -20)
        ;;
    apollo)
        # GraphQL resolvers
        ENDPOINTS=$(grep -r "Query\\|Mutation" --include="*.ts" --include="*.js" \
                         --exclude-dir=node_modules . | head -20)
        ;;
    fastapi)
        ENDPOINTS=$(grep -r "@app\.\(get\|post\|put\|delete\|patch\)" --include="*.py" . | head -20)
        ;;
    flask)
        ENDPOINTS=$(grep -r "@app\.route" --include="*.py" . | head -20)
        ;;
    django)
        ENDPOINTS=$(find . -name "urls.py" -o -name "views.py" | head -20)
        ;;
esac

if [ -z "$ENDPOINTS" ]; then
    echo "⚠️ No API endpoints found"
    exit 1
fi

ENDPOINT_COUNT=$(echo "$ENDPOINTS" | wc -l)
echo "✓ Found $ENDPOINT_COUNT endpoints"
echo ""
echo "Sample endpoints:"
echo "$ENDPOINTS" | head -5 | sed 's/^/  /'
```

## Phase 3: Test Framework Setup

```bash
echo ""
echo "Setting up test framework..."

# Detect or install test framework
if [ "$FRAMEWORK" = "express" ] || [ "$FRAMEWORK" = "fastify" ] || [ "$FRAMEWORK" = "nextjs" ]; then
    # Node.js - use supertest + jest
    if ! grep -q "\"supertest\"" package.json; then
        echo "Installing supertest for API testing..."
        npm install --save-dev supertest @types/supertest
    fi

    if ! grep -q "\"jest\"" package.json; then
