# 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
```bash
# 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
1. POST /recommend with WordPress stack (nginx, php-fpm, mysql)
2. Extract instance_id from first recommendation
3. GET /instances to fetch detailed specs
4. 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
1. GET /instances?max_price=50&sort_by=price&order=asc
2. Validate all results are within budget ($50/month)
3. 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
1. GET /instances?region=ap-northeast-1 (Tokyo)
2. GET /instances?region=ap-northeast-2 (Seoul)
3. 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
1. POST /sync with provider: linode
2. GET /health to verify sync_status
3. 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
1. Send 10 rapid requests to /instances
2. Check for 429 Too Many Requests response
3. Verify Retry-After header
**Run**: `npx tsx scripts/e2e-tester.ts --scenario ratelimit`
---
### E2E Command Line Options
**Run All Scenarios**:
```bash
npm run test:e2e
```
**Run Specific Scenario**:
```bash
npx tsx scripts/e2e-tester.ts --scenario <name>
```
Available scenarios: `wordpress`, `budget`, `region`, `sync`, `ratelimit`
**Dry Run (Preview Only)**:
```bash
npm run test:e2e:dry
```
**Combine Options**:
```bash
npx tsx scripts/e2e-tester.ts --scenario wordpress --dry-run
```
### E2E Example Output

## 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:
```bash
npx tsx scripts/api-tester.ts
```
#### Filter by Endpoint
Test only specific endpoint:
```bash
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:
```bash
npx tsx scripts/api-tester.ts --verbose
```
Combine with endpoint filter:
```bash
npx tsx scripts/api-tester.ts --endpoint=/instances --verbose
```
#### Environment Variables
Override API URL and key:
```bash
API_URL=https://my-api.example.com API_KEY=my-secret-key npx tsx scripts/api-tester.ts
```
### Test Coverage

- Price filter (`max_price`)
- GPU filter (`has_gpu=true`)
- Sorting (`sort_by=price`, `order=asc/desc`)
- Pagination (`limit`, `offset`)
- Combined filters
- Invalid provider (error case)
- No authentication (error case)
#### /sync Endpoint
- Linode provider sync
- Invalid provider (error case)

# API Tester Script Summary
## Files Created
1. **scripts/api-tester.ts** (663 lines)
- Main test script with comprehensive endpoint coverage
2. **scripts/README.md**
- Detailed usage documentation
- Test coverage overview
- Example output
## Key Features Implemented
### Architecture
- **TypeScript**: Full type safety with interfaces for requests/responses
- **Modular Design**: Separate test suites per endpoint
- **Color System**: ANSI color codes for terminal output
- **Validation Framework**: Response schema validators for each endpoint
### Test Coverage (24 Total Tests)
#### Health Endpoint (2 tests)
- Unauthenticated access
- Authenticated access
#### Instances Endpoint (11 tests)
- Basic query
- Provider filtering (linode/vultr/aws)
- Resource filtering (memory, CPU, price, GPU)
- Sorting and pagination
- Combined filters
- Error cases (invalid provider, missing auth)
#### Sync Endpoint (3 tests)
- Successful sync
- Invalid provider
- Missing authentication
#### Recommend Endpoint (6 tests)
- Various stack combinations
- Scale variations (small/medium/large)
- Budget constraints
- Error cases (invalid stack/scale)
- Missing authentication
### CLI Features
- `--endpoint=/path` - Filter to specific endpoint
- `--verbose` - Show full response bodies
- Environment variable overrides (API_URL, API_KEY)
- Exit codes (0 = pass, 1 = fail)
### Response Validation
Each endpoint has dedicated validators checking:
- Response structure (required fields)
- Data types
- Success/error status
- Nested object validation
### Output Design
```
🧪 Title with emoji
📍 Section headers
✅ Success (green)
❌ Failure (red)
⚠️ Warnings (yellow)
(123ms) - Gray timing info
```
## Usage Examples
```bash
# Run all tests
npx tsx scripts/api-tester.ts
# Test specific endpoint
npx tsx scripts/api-tester.ts --endpoint=/instances
# Verbose mode
npx tsx scripts/api-tester.ts --verbose
# Custom API configuration
API_URL=https://staging.example.com API_KEY=abc123 npx tsx scripts/api-tester.ts
```
## Implementation Highlights
### Error Handling
- Try-catch wrapping all network requests
- Graceful degradation for validation failures
- Detailed error messages with context
### Performance Measurement
- Per-request timing (Date.now() before/after)
- Total test suite duration
- Response time included in output
### Type Safety
- Interface definitions for all data structures
- Generic validators with type guards
- Compile-time safety for test configuration
## Code Quality
- **Naming**: Clear, descriptive function/variable names
- **Comments**: Comprehensive documentation throughout
- **Structure**: Logical sections with separators
- **DRY**: Reusable helper functions (testRequest, validators)
- **Error Messages**: Informative and actionable
## Extension Points
The script is designed for easy extension:
1. **Add New Tests**: Create new test functions following pattern
2. **Custom Validators**: Add validator functions for new endpoints
3. **Output Formats**: Modify printTestResult for different displays
4. **Reporting**: Extend TestReport interface for analytics
## Dependencies
- **Runtime**: Node.js 18+ (native fetch API)
- **Execution**: tsx (TypeScript execution)
- **No Additional Packages**: Uses only Node.js built-ins
## Production Ready
- Safe for production testing (read-only operations except controlled sync)
- Non-invasive error handling
- Clear success/failure reporting
- Comprehensive validation without false positives
