# KMS API - Failing Tests Analysis & Resolution Prompt
## Context
I have a Go-based Key Management Service (KMS) API with comprehensive end-to-end tests. The server is running successfully on port 8081, but several tests are failing due to database connectivity issues and some implementation gaps. I need help resolving these failing tests.
## Current Test Results
**Total Tests**: 22
**Passing**: 17
**Failing**: 6
## Failing Tests Analysis
### 1. Database Connectivity Issues (Primary Problem)
```
[FAIL] Readiness Check (Expected: 200, Got: 503)
Response: {"status":"not ready","timestamp":"2025-08-22T17:17:03Z","checks":{"database":"unhealthy: sql: database is closed"}}
[FAIL] List applications with auth (Expected: 200, Got: 500)
Response: {"error":"Internal Server Error","message":"Failed to list applications"}
[FAIL] List applications with pagination (Expected: 200, Got: 500)
Response: {"error":"Internal Server Error","message":"Failed to list applications"}
[FAIL] Create application (Expected: 201, Got: 500)
Response: {"error":"Internal Server Error","message":"Failed to create application"}
[FAIL] Missing content-type (Expected: 400, Got: 500)
Response: {"error":"Internal Server Error","message":"Failed to create application"}
```
**Root Cause**: The server logs show `"sql: database is closed"` errors. The PostgreSQL database is not running or not properly connected.
### 2. Edge Case Handling
```
[FAIL] Delete non-existent token (Expected: 500, Got: 204)
```
**Issue**: The delete token endpoint returns 204 (success) even for non-existent tokens, but the test expects 500 (error).
## What Needs to be Completed
### Priority 1: Database Setup & Connection
1. **Start PostgreSQL Database**
- Either start a local PostgreSQL instance
- Or set up Docker container with PostgreSQL
- Or configure the application to use an in-memory/mock database for testing
2. **Database Configuration**
- Verify database connection string in configuration
- Ensure database migrations run successfully
- Check that database tables are created properly
3. **Connection Pool Management**
- Fix the "database is closed" error
- Ensure proper database connection lifecycle management
- Verify connection pool settings
### Priority 2: Application Service Implementation
The application CRUD operations are failing, which suggests:
1. **Repository Layer**: Verify PostgreSQL repository implementations work correctly
2. **Service Layer**: Ensure application service properly handles database operations
3. **Error Handling**: Improve error responses for database connectivity issues
### Priority 3: Token Service Edge Cases
1. **Delete Token Validation**: The delete token endpoint should return appropriate error codes for non-existent tokens
2. **Error Response Consistency**: Ensure consistent error handling across all endpoints
## Technical Details
### Server Configuration
- **Server Port**: 8081 (8080 was in use)
- **Database**: PostgreSQL (currently not connected)
- **Framework**: Gin (Go web framework)
- **Architecture**: Clean architecture with repositories, services, and handlers
### Key Files to Examine
- `cmd/server/main.go` - Server startup and database initialization
- `internal/database/postgres.go` - Database connection management
- `internal/services/application_service.go` - Application CRUD operations
- `internal/services/token_service.go` - Token management
- `docker-compose.yml` - Database container configuration
- `migrations/001_initial_schema.up.sql` - Database schema
### Current Working State
✅ **Working Endpoints**:
- Health check (basic)
- Authentication (login, verify, renew)
- Token operations (create, list, delete - when not requiring complex validation)
- Error handling for malformed JSON
- API documentation
❌ **Failing Endpoints**:
- Readiness check (database health)
- Application CRUD operations
- Some edge case validations
## Success Criteria
After resolution, all 22 tests should pass:
1. Database connectivity restored (readiness check returns 200)
2. Application CRUD operations working (create, read, update, delete, list)
3. Proper error handling for edge cases
4. All endpoints returning expected HTTP status codes
## How to Test
Run the E2E test script to verify fixes:
```bash
BASE_URL=http://localhost:8081 ./test/e2e_test.sh
```
The test script provides detailed output showing exactly which endpoints are failing and what responses they're returning versus what's expected.
## Additional Context
- The server starts successfully and handles HTTP requests
- Authentication middleware is working correctly
- The issue appears to be primarily database-related
- Some service implementations may have placeholder code that needs completion
- The test suite is comprehensive and will clearly show when issues are resolved

A comprehensive, secure API Key Management Service built in modern Go, designed to scale to millions of concurrent requests.
## Features
- **Scalable Architecture**: Built with interfaces and dependency injection for easy extension
- **Dual Token Types**: Support for both static API keys and user JWT tokens
- **Permission System**: Hierarchical permission scopes with granular access control
- **Multiple Auth Providers**: Header-based and SSO authentication providers
- **Rate Limiting**: Configurable rate limiting to prevent abuse
- **Security**: Comprehensive security headers, CORS, and secure token handling
- **Database**: PostgreSQL with proper migrations and connection pooling
- **Monitoring**: Health checks, metrics, and structured logging
- **Docker Ready**: Complete Docker Compose setup for easy deployment
## Architecture
The service follows clean architecture principles with clear separation of concerns:
```
cmd/server/ - Application entry point
internal/
├── domain/ - Domain models and business logic
├── repository/ - Data access interfaces and implementations
├── services/ - Business logic layer
├── handlers/ - HTTP request handlers
├── middleware/ - HTTP middleware components
├── config/ - Configuration management
└── database/ - Database connection and migrations
```
## Quick Start
### Prerequisites
- Docker and Docker Compose
- Go 1.21+ (for local development)
### Running with Docker Compose
1. **Start the services:**
```bash
docker-compose up -d
```
This starts:
- PostgreSQL database on port 5432
- API service on port 8080
- Nginx proxy on port 80
- Metrics endpoint on port 9090
2. **Check service health:**
```bash
curl http://localhost/health
```
3. **View API documentation:**
```bash
curl http://localhost/api/docs
```
### Configuration
The service is configured via environment variables. Key settings:
```env
# Database
DB_HOST=localhost
DB_PORT=5432
DB_NAME=kms
DB_USER=postgres
DB_PASSWORD=postgres
# Server
SERVER_HOST=0.0.0.0
SERVER_PORT=8080
# Authentication
AUTH_PROVIDER=header
AUTH_HEADER_USER_EMAIL=X-User-Email
# Security
RATE_LIMIT_ENABLED=true
RATE_LIMIT_RPS=100
RATE_LIMIT_BURST=200
```
## API Usage
### Authentication
All protected endpoints require the `X-User-Email` header when using the HeaderAuthenticationProvider:
```bash
curl -H "X-User-Email: admin@example.com" \
-H "Content-Type: application/json" \
http://localhost/api/applications
```
### Creating an Application
```bash
curl -X POST http://localhost/api/applications \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"app_id": "com.mycompany.api",
"app_link": "https://api.mycompany.com",
"type": ["static", "user"],
"callback_url": "https://api.mycompany.com/callback",
"token_renewal_duration": "168h",
"max_token_duration": "720h",
"owner": {
"type": "team",
"name": "API Team",
"owner": "api-team@mycompany.com"
}
}'
```
### Creating a Static Token
```bash
curl -X POST http://localhost/api/applications/com.mycompany.api/tokens \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"owner": {
"type": "individual",
"name": "Service Account",
"owner": "service@mycompany.com"
},
"permissions": ["repo.read", "repo.write"]
}'
```
### Token Verification
```bash
curl -X POST http://localhost/api/verify \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"type": "static",
"token": "your-static-token-here",
"permissions": ["repo.read"]
}'
```
## Permission Scopes
The service includes a hierarchical permission system:
### System Permissions
- `internal` - Full access to internal system operations
- `internal.admin` - Administrative access to internal system
### Application Management
- `app.read` - Read application information
- `app.write` - Create and update applications
- `app.delete` - Delete applications
### Token Management
- `token.read` - Read token information
- `token.create` - Create new tokens
- `token.revoke` - Revoke existing tokens
### Repository Access (Example)
- `repo.read` - Read repository data
- `repo.write` - Write to repositories
- `repo.admin` - Administrative access to repositories
## Development
### Local Development
1. **Install dependencies:**
```bash
go mod download
```
2. **Run database migrations:**
```bash
# Using Docker for PostgreSQL
docker run --name kms-postgres -e POSTGRES_DB=kms -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:15-alpine
```
3. **Run the service:**
```bash
go run cmd/server/main.go
```
### Testing
The service includes comprehensive logging and can be tested at different user levels:
- **Port 80**: Regular user (`test@example.com`)
- **Port 8081**: Admin user (`admin@example.com`)
- **Port 8082**: Limited user (`limited@example.com`)
### Building with distrobox
If you have distrobox available:
```bash
distrobox create --name golang-dev --image golang:1.21-alpine
distrobox enter golang-dev
cd /path/to/project
go build -o api-key-service ./cmd/server
```
## Security Features
- **Rate Limiting**: Configurable per-endpoint rate limits
- **Security Headers**: Comprehensive security headers on all responses
- **CORS**: Configurable Cross-Origin Resource Sharing
- **Token Security**: Secure token generation and validation
- **Permission Validation**: Hierarchical permission checking
- **Audit Logging**: All operations logged with user attribution
- **Input Validation**: Request validation with detailed error messages
## Monitoring
### Health Checks
- `GET /health` - Basic health check
- `GET /ready` - Readiness check with database connectivity
### Metrics
- `GET /metrics` - Prometheus-style metrics (when enabled)
### Logging
Structured JSON logging with configurable levels:
- Request/response logging
- Error tracking with stack traces
- Performance metrics
- Security events
## Database Schema
The service uses PostgreSQL with the following key tables:
- `applications` - Application definitions
- `static_tokens` - Static API tokens
- `available_permissions` - Permission catalog
- `granted_permissions` - Token-permission relationships
Migrations are automatically applied on startup.
## Production Considerations
1. **Security**:
- Change default HMAC keys
- Use HTTPS in production
- Configure proper CORS origins
- Set up proper authentication provider
2. **Performance**:
- Tune database connection pools
- Configure appropriate rate limits
- Set up load balancing
- Monitor metrics and logs
3. **High Availability**:
- Run multiple service instances
- Use database clustering
- Implement health check monitoring
- Set up proper backup procedures
## API Documentation
Comprehensive API documentation is available in [`docs/API.md`](docs/API.md), including:
- Complete endpoint reference
- Request/response examples
- Error handling
- Authentication flows
- Rate limiting details
- Security considerations
## Architecture Decisions
- **Interface-based Design**: All dependencies are injected as interfaces for easy testing and replacement
- **Clean Architecture**: Clear separation between domain, service, and infrastructure layers
- **Security First**: Built with security considerations from the ground up
- **Scalability**: Designed to handle millions of concurrent requests
- **Observability**: Comprehensive logging, metrics, and health checks
- **Configuration**: Environment-based configuration with sensible defaults
## Contributing
The codebase follows Go best practices and clean architecture principles. Key patterns:
- Repository pattern for data access
- Service layer for business logic
- Middleware for cross-cutting concerns
- Dependency injection throughout
- Comprehensive error handling
- Structured logging

## Permission Scopes
The following permission scopes are available:
### System Permissions
- `internal` - Full access to internal system operations (system only)
- `internal.read` - Read access to internal system data (system only)
- `internal.write` - Write access to internal system data (system only)
- `internal.admin` - Administrative access to internal system (system only)
### Application Management
- `app` - Access to application management
- `app.read` - Read application information
- `app.write` - Create and update applications
- `app.delete` - Delete applications
### Token Management
- `token` - Access to token management
- `token.read` - Read token information
- `token.create` - Create new tokens
- `token.revoke` - Revoke existing tokens
### Permission Management
- `permission` - Access to permission management
- `permission.read` - Read permission information
- `permission.write` - Create and update permissions
- `permission.grant` - Grant permissions to tokens
- `permission.revoke` - Revoke permissions from tokens
### Repository Access (Example)
- `repo` - Access to repository operations
- `repo.read` - Read repository data
- `repo.write` - Write to repositories
- `repo.admin` - Administrative access to repositories
## Rate Limiting
The API implements rate limiting with the following limits:
- **General API endpoints**: 100 requests per minute with burst of 20
- **Authentication endpoints** (`/login`, `/verify`, `/renew`): 10 requests per minute with burst of 5
Rate limit headers are included in responses:
- `X-RateLimit-Limit`: Request limit per window
- `X-RateLimit-Remaining`: Remaining requests in current window
- `X-RateLimit-Reset`: Unix timestamp when the window resets
When rate limited:
```json
{
"error": "Rate limit exceeded",
"message": "Too many requests. Please try again later."
}
```
## Testing Endpoints
For testing purposes, different user scenarios are available through different ports:
- **Port 80**: Regular user (`test@example.com`)
- **Port 8081**: Admin user (`admin@example.com`) with higher rate limits
- **Port 8082**: Limited user (`limited@example.com`) with lower rate limits
## Example Workflows
### Creating an Application and Static Token
1. **Create Application:**
```bash
curl -X POST http://localhost/api/applications \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"app_id": "com.mycompany.api",
"app_link": "https://api.mycompany.com",
"type": ["static", "user"],
"callback_url": "https://api.mycompany.com/callback",
"token_renewal_duration": "168h",
"max_token_duration": "720h",
"owner": {
"type": "team",
"name": "API Team",
"owner": "api-team@mycompany.com"
}
}'
```
2. **Create Static Token:**
```bash
curl -X POST http://localhost/api/applications/com.mycompany.api/tokens \
-H "Content-Type: application/json" \
-H "X-User-Email: admin@example.com" \
-d '{
"owner": {
"type": "individual",
"name": "Service Account",
"owner": "service@mycompany.com"
},
"permissions": ["repo.read", "repo.write"]
}'
```
3. **Verify Token:**
```bash
curl -X POST http://localhost/api/verify \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"type": "static",
"token": "static-token-abc123xyz789",
"permissions": ["repo.read"]
}'
```
### User Authentication Flow
1. **Initiate Login:**
```bash
curl -X POST http://localhost/api/login \
-H "Content-Type: application/json" \
-H "X-User-Email: user@example.com" \
-d '{
"app_id": "com.mycompany.api",
"permissions": ["repo.read"],
"redirect_uri": "https://myapp.com/callback"
}'
```
2. **Verify User Token:**
```bash
curl -X POST http://localhost/api/verify \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"type": "user",
"user_id": "user@example.com",
"token": "user-token-from-login",
"permissions": ["repo.read"]
}'
```
3. **Renew Token Before Expiry:**
```bash
curl -X POST http://localhost/api/renew \
-H "Content-Type: application/json" \
-d '{
"app_id": "com.mycompany.api",
"user_id": "user@example.com",
"token": "current-user-token"
}'
```
## Security Considerations
- All tokens should be transmitted over HTTPS in production
- Static tokens are returned only once during creation - store them securely
- User tokens have both renewal and maximum validity periods
- HMAC keys are used for token signing and should be rotated regularly
- Rate limiting helps prevent abuse
- Permission scopes follow hierarchical structure
- All operations are logged with user attribution
## Development and Testing
The service includes comprehensive health checks, detailed logging, and metrics collection. When running with `LOG_LEVEL=debug`, additional debugging information is available in the logs.
For local development, the service can be started with:
```bash
docker-compose up -d
```
This starts PostgreSQL, the API service, and Nginx proxy with test user headers configured.

# End-to-End Testing Guide
This document describes how to run end-to-end tests for the KMS (Key Management Service) API using the provided bash script.
## Overview
The `e2e_test.sh` script provides comprehensive end-to-end testing of the KMS API using curl commands. It tests all major functionality including health checks, authentication, application management, and token operations.
## Prerequisites
- `curl` command-line tool installed
- KMS server running (either locally or remotely)
- Bash shell environment
## Quick Start
### 1. Start the KMS Server
First, make sure your KMS server is running. You can start it using Docker Compose:
```bash
# From the project root directory
docker-compose up -d
```
Or run it directly:
```bash
go run cmd/server/main.go
```
### 2. Run the E2E Tests
```bash
# Run with default settings (server at localhost:8080)
./test/e2e_test.sh
# Or run with custom configuration
BASE_URL=http://localhost:8080 USER_EMAIL=admin@example.com ./test/e2e_test.sh
```
## Configuration
The script supports several environment variables for configuration:
| Variable | Default | Description |
|----------|---------|-------------|
| `BASE_URL` | `http://localhost:8080` | Base URL of the KMS server |
| `USER_EMAIL` | `test@example.com` | User email for authentication headers |
| `USER_ID` | `test-user-123` | User ID for authentication headers |
### Examples
```bash
# Test against a remote server
BASE_URL=https://kms-api.example.com ./test/e2e_test.sh
# Use different user credentials
USER_EMAIL=admin@company.com USER_ID=admin-456 ./test/e2e_test.sh
# Test against local server on different port
BASE_URL=http://localhost:3000 ./test/e2e_test.sh
```
## Test Coverage
The script tests the following functionality:
### Health Endpoints
- `GET /health` - Basic health check
- `GET /ready` - Readiness check with database connectivity
### Authentication Endpoints
- `POST /api/login` - User login (with and without auth headers)
- `POST /api/verify` - Token verification
- `POST /api/renew` - Token renewal
### Application Management
- `GET /api/applications` - List applications (with pagination)
- `POST /api/applications` - Create new application
- `GET /api/applications/:id` - Get application by ID
- `PUT /api/applications/:id` - Update application
- `DELETE /api/applications/:id` - Delete application
### Token Management
- `GET /api/applications/:id/tokens` - List tokens for application
- `POST /api/applications/:id/tokens` - Create static token
- `DELETE /api/tokens/:id` - Delete token
### Error Handling
- Invalid endpoints (404 errors)
- Malformed JSON requests
- Missing authentication headers
- Invalid request formats
### Documentation
- `GET /api/docs` - API documentation endpoint
## Output Format
The script provides colored output with clear test results:
- 🔵 **[INFO]** - General information and test progress
- 🟢 **[PASS]** - Successful test cases
- 🔴 **[FAIL]** - Failed test cases
- 🟡 **[WARN]** - Warnings and non-critical issues
### Sample Output
```
[INFO] Starting End-to-End Tests for KMS API
[INFO] Base URL: http://localhost:8080
[INFO] User Email: test@example.com
[INFO] User ID: test-user-123
[INFO] Waiting for server to be ready...
[PASS] Server is ready!
[INFO] === Testing Health Endpoints ===
[INFO] Running test: Health Check
[PASS] Health Check (Status: 200)
Response: {"status":"healthy","timestamp":"2025-08-22T17:13:26Z"}
[INFO] Running test: Readiness Check
[PASS] Readiness Check (Status: 200)
Response: {"status":"ready","timestamp":"2025-08-22T17:13:26Z","checks":{"database":"healthy"}}
...
[INFO] === Test Summary ===
Tests Run: 25
Tests Passed: 23
Tests Failed: 2
Some tests failed!
```
## Features
### Automatic Server Detection
The script waits for the server to be ready before running tests, with a configurable timeout.
### Dynamic Test Data
- Creates test applications and extracts their IDs for subsequent tests
- Creates test tokens and uses them for deletion tests
- Automatically cleans up test data after completion
### Comprehensive Error Testing
Tests various error conditions including:
- Missing authentication
- Invalid JSON payloads
- Non-existent resources
- Malformed requests
### Robust Error Handling
- Graceful handling of network errors
- Automatic cleanup on script interruption
- Clear error messages and status codes
## Troubleshooting
### Common Issues
1. **Server Not Ready**
```
[FAIL] Server failed to start within timeout
```
- Ensure the KMS server is running
- Check if the server is accessible at the configured URL
- Verify database connectivity
2. **Authentication Failures**
```
[FAIL] List applications with auth (Expected: 200, Got: 401)
```
- Check if authentication middleware is properly configured
- Verify the authentication headers are being processed correctly
3. **Database Connection Issues**
```
[FAIL] Readiness Check (Expected: 200, Got: 503)
```
- Ensure PostgreSQL database is running
- Check database connection configuration
- Verify database migrations have been applied
### Debug Mode
For more detailed output, you can modify the script to include verbose curl output:
```bash
# Add -v flag to curl commands for verbose output
# Edit the run_test function in e2e_test.sh
```
### Manual Testing
You can also run individual curl commands manually for debugging:
```bash
# Test health endpoint
curl -v http://localhost:8080/health
# Test authentication
curl -v -X POST http://localhost:8080/api/login \
-H "Content-Type: application/json" \
-H "X-User-Email: test@example.com" \
-H "X-User-ID: test-user-123" \
-d '{"app_id": "test-app", "permissions": ["read"]}'
```
## Integration with CI/CD
The script is designed to work well in CI/CD pipelines:
```yaml
# Example GitHub Actions workflow
- name: Run E2E Tests
run: |
docker-compose up -d
sleep 10 # Wait for services to start
./test/e2e_test.sh
docker-compose down
env:
BASE_URL: http://localhost:8080
USER_EMAIL: ci@example.com
```
## Extending the Tests
To add new test cases:
1. Create a new test function following the pattern `test_*`
2. Use the `run_test` helper function for consistent output
3. Add the function call to the `main()` function
4. Update this documentation
Example:
```bash
test_new_feature() {
log_info "=== Testing New Feature ==="
run_test "New feature test" "200" \
-X GET "$API_BASE/new-endpoint" \
-H "X-User-Email: $USER_EMAIL" \
-H "X-User-ID: $USER_ID"
}

# Integration Tests for API Key Management Service
This directory contains comprehensive end-to-end integration tests for the API Key Management Service.
## Test Coverage
The integration tests cover:
### 1. **Health Check Endpoints**
- Basic health check (`/health`)
- Readiness check with database connectivity (`/ready`)
### 2. **Application CRUD Operations**
- Create new applications
- List applications with pagination
- Get specific applications by ID
- Update application details
- Delete applications
### 3. **Static Token Workflow**
- Create static tokens for applications
- Verify static token permissions
- Token validation and permission checking
### 4. **User Token Authentication Flow**
- User login process
- Token generation for users
- Permission-based access control
### 5. **Authentication Middleware**
- Header-based authentication validation
- Unauthorized access handling
- User context management
### 6. **Error Handling**
- Invalid JSON request handling
- Non-existent resource handling
- Proper HTTP status codes
### 7. **Concurrent Load Testing**
- Multiple simultaneous health checks
- Concurrent application listing requests
- Database connection pooling under load
## Prerequisites
Before running the integration tests, ensure you have:
1. **PostgreSQL Database**: Running on localhost:5432
2. **Test Database**: Create a test database named `kms_test`
3. **Go Dependencies**: All required Go modules installed
### Database Setup
```bash
# Connect to PostgreSQL
psql -U postgres -h localhost
# Create test database
CREATE DATABASE kms_test;
# Grant permissions
GRANT ALL PRIVILEGES ON DATABASE kms_test TO postgres;
```
## Running the Tests
### Option 1: Run All Integration Tests
```bash
# From the project root directory
go test -v ./test/...
```
### Option 2: Run with Coverage
```bash
# Generate coverage report
go test -v -coverprofile=coverage.out ./test/...
go tool cover -html=coverage.out -o coverage.html
```
### Option 3: Run Specific Test Suites
```bash
# Run only health endpoint tests
go test -v ./test/ -run TestHealthEndpoints
# Run only application CRUD tests
go test -v ./test/ -run TestApplicationCRUD
# Run only token workflow tests
go test -v ./test/ -run TestStaticTokenWorkflow
# Run concurrent load tests
go test -v ./test/ -run TestConcurrentRequests
```
### Option 4: Run with Docker/Podman
```bash
# Start the services first
podman-compose up -d
# Wait for services to be ready
sleep 10
# Run the tests
go test -v ./test/...
# Clean up
podman-compose down
```
## Test Configuration
The tests use a separate test configuration that:
- Uses a dedicated test database (`kms_test`)
- Disables rate limiting for testing
- Disables metrics collection
- Uses debug logging level
- Configures shorter timeouts
## Test Data Management
The integration tests:
- **Clean up after themselves**: Each test cleans up its test data
- **Use isolated data**: Test data is prefixed with `test-` to avoid conflicts
- **Reset state**: Database state is reset between test runs
- **Use transactions**: Where possible, tests use database transactions
## Expected Test Results
When all tests pass, you should see output similar to:
```
=== RUN TestIntegrationSuite
=== RUN TestIntegrationSuite/TestHealthEndpoints
=== RUN TestIntegrationSuite/TestApplicationCRUD
=== RUN TestIntegrationSuite/TestApplicationCRUD/CreateApplication
=== RUN TestIntegrationSuite/TestApplicationCRUD/ListApplications
=== RUN TestIntegrationSuite/TestApplicationCRUD/GetApplication
=== RUN TestIntegrationSuite/TestStaticTokenWorkflow
=== RUN TestIntegrationSuite/TestStaticTokenWorkflow/CreateStaticToken
=== RUN TestIntegrationSuite/TestStaticTokenWorkflow/VerifyStaticToken
=== RUN TestIntegrationSuite/TestUserTokenWorkflow
=== RUN TestIntegrationSuite/TestUserTokenWorkflow/UserLogin
=== RUN TestIntegrationSuite/TestAuthenticationMiddleware
=== RUN TestIntegrationSuite/TestAuthenticationMiddleware/MissingAuthHeader
=== RUN TestIntegrationSuite/TestAuthenticationMiddleware/ValidAuthHeader
=== RUN TestIntegrationSuite/TestErrorHandling
=== RUN TestIntegrationSuite/TestErrorHandling/InvalidJSON
=== RUN TestIntegrationSuite/TestErrorHandling/NonExistentApplication
=== RUN TestIntegrationSuite/TestConcurrentRequests
=== RUN TestIntegrationSuite/TestConcurrentRequests/ConcurrentHealthChecks
=== RUN TestIntegrationSuite/TestConcurrentRequests/ConcurrentApplicationListing
--- PASS: TestIntegrationSuite (2.34s)
PASS
```
## Troubleshooting
### Common Issues
1. **Database Connection Failed**
```
Error: failed to connect to database
```
- Ensure PostgreSQL is running
- Check database credentials
- Verify test database exists
2. **Migration Errors**
```
Error: failed to run migrations
```
- Ensure migration files are in the correct location
- Check database permissions
- Verify migration file format
3. **Port Already in Use**
```
Error: bind: address already in use
```
- The test server uses random ports, but check if other services are running
- Stop any running instances of the API service
4. **Test Timeouts**
```
Error: test timed out
```
- Increase test timeout values
- Check database performance
- Verify network connectivity
### Debug Mode
To run tests with additional debugging:
```bash
# Enable debug logging
LOG_LEVEL=debug go test -v ./test/...
# Run with race detection
go test -race -v ./test/...
# Run with memory profiling
go test -memprofile=mem.prof -v ./test/...
```
## Test Architecture
The integration tests use:
- **testify/suite**: For organized test suites with setup/teardown
- **httptest**: For HTTP server testing
- **testify/assert**: For test assertions
- **testify/require**: For test requirements
The test structure follows the same clean architecture as the main application:
```
test/
├── integration_test.go # Main integration test suite
├── test_helpers.go # Test utilities and mocks
└── README.md # This documentation
```
## Contributing
When adding new integration tests:
1. Follow the existing test patterns
2. Clean up test data properly
3. Use descriptive test names
4. Add appropriate assertions
5. Update this README if needed
## Performance Benchmarks
The concurrent load tests provide basic performance benchmarks:
- **Health Check Load**: 50 concurrent requests
- **Application Listing Load**: 20 concurrent requests
- **Expected Response Time**: < 100ms for health checks
- **Expected Throughput**: > 100 requests/second
These benchmarks help ensure the service can handle reasonable concurrent load.
