API Testing Scripts
This directory contains two types of API testing scripts:
- api-tester.ts: Endpoint-level testing (unit/integration)
- e2e-tester.ts: End-to-end scenario testing (workflow validation)
e2e-tester.ts
End-to-End testing script that validates complete user workflows against the deployed production API.
Quick Start
# Run all scenarios
npm run test:e2e
# Dry run (preview without actual API calls)
npm run test:e2e:dry
# Run specific scenario
npx tsx scripts/e2e-tester.ts --scenario wordpress
npx tsx scripts/e2e-tester.ts --scenario budget
Scenarios
Scenario 1: WordPress Server Recommendation
Flow: Recommendation → Detail Lookup → Validation
- POST /recommend with WordPress stack (nginx, php-fpm, mysql)
- Extract instance_id from first recommendation
- GET /instances to fetch detailed specs
- Validate specs meet requirements (memory >= 3072MB, vCPU >= 2)
Run: npx tsx scripts/e2e-tester.ts --scenario wordpress
Scenario 2: Budget-Constrained Search
Flow: Price Filter → Validation
- GET /instances?max_price=50&sort_by=price&order=asc
- Validate all results are within budget ($50/month)
- Validate ascending price sort order
Run: npx tsx scripts/e2e-tester.ts --scenario budget
Scenario 3: Cross-Region Price Comparison
Flow: Multi-Region Query → Price Analysis
- GET /instances?region=ap-northeast-1 (Tokyo)
- GET /instances?region=ap-northeast-2 (Seoul)
- Calculate average prices and compare regions
Run: npx tsx scripts/e2e-tester.ts --scenario region
Scenario 4: Provider Sync Verification
Flow: Sync → Health Check → Data Validation
- POST /sync with provider: linode
- GET /health to verify sync_status
- GET /instances?provider=linode to confirm data exists
Run: npx tsx scripts/e2e-tester.ts --scenario sync
Scenario 5: Rate Limiting Test
Flow: Burst Requests → Rate Limit Detection
- Send 10 rapid requests to /instances
- Check for 429 Too Many Requests response
- Verify Retry-After header
Run: npx tsx scripts/e2e-tester.ts --scenario ratelimit
E2E Command Line Options
Run All Scenarios:
npm run test:e2e
Run Specific Scenario:
npx tsx scripts/e2e-tester.ts --scenario <name>
Available scenarios: wordpress, budget, region, sync, ratelimit
Dry Run (Preview Only):
npm run test:e2e:dry
Combine Options:

api-tester.ts
Comprehensive API endpoint tester for the Cloud Instances API.
Features
- Tests all API endpoints with various parameter combinations
- Colorful console output with status indicators (✅❌⚠️)
- Response time measurement for each test
- Response schema validation
- Support for filtered testing (specific endpoints)
- Verbose mode for detailed response inspection
- Environment variable support for API configuration
Usage
Basic Usage
Run all tests:
npx tsx scripts/api-tester.ts
Filter by Endpoint
Test only specific endpoint:
npx tsx scripts/api-tester.ts --endpoint=/health
npx tsx scripts/api-tester.ts --endpoint=/instances
npx tsx scripts/api-tester.ts --endpoint=/sync
npx tsx scripts/api-tester.ts --endpoint=/recommend
Verbose Mode
Show full response bodies:
npx tsx scripts/api-tester.ts --verbose
Combine with endpoint filter:
npx tsx scripts/api-tester.ts --endpoint=/instances --verbose
Environment Variables
Override API URL and key:
API_URL=https://my-api.example.com API_KEY=my-secret-key npx tsx scripts/api-tester.ts
Test Coverage
/health Endpoint
- GET without authentication
- GET with authentication

Notes
- Tests are designed to be non-destructive (safe to run against production)
- Sync endpoint tests use only the 'linode' provider to minimize impact
- Response validation checks basic structure and required fields
- Timing measurements include network latency
- Color output is optimized for dark terminal themes
