# Integration Tests
This directory contains integration tests for the Calypso API.
## Setup
### 1. Create Test Database (Optional)
For isolated testing, create a separate test database:
```bash
sudo -u postgres createdb calypso_test
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE calypso_test TO calypso;"
```
### 2. Environment Variables
Set test database configuration:
```bash
export TEST_DB_HOST=localhost
export TEST_DB_PORT=5432
export TEST_DB_USER=calypso
export TEST_DB_PASSWORD=calypso123
export TEST_DB_NAME=calypso_test # or use existing 'calypso' database
```
Or use the existing database:
```bash
export TEST_DB_NAME=calypso
export TEST_DB_PASSWORD=calypso123
```
## Running Tests
### Run All Integration Tests
```bash
cd backend
go test ./tests/integration/... -v
```
### Run Specific Test
```bash
go test ./tests/integration/... -run TestHealthEndpoint -v
```
### Run with Coverage
```bash
go test -cover ./tests/integration/... -v
```
## Test Structure
- `setup.go` - Test database setup and helper functions
- `api_test.go` - API endpoint integration tests
## Test Coverage
### ✅ Implemented Tests
1. **TestHealthEndpoint** - Tests enhanced health check endpoint
2. **TestLoginEndpoint** - Tests user login with password verification
3. **TestLoginEndpoint_WrongPassword** - Tests wrong password rejection
4. **TestGetCurrentUser** - Tests authenticated user info retrieval
5. **TestListAlerts** - Tests monitoring alerts endpoint
### ⏳ Future Tests
- Storage endpoints
- SCST endpoints
- VTL endpoints
- Task management
- IAM endpoints
## Notes
- Tests use the actual database (test or production)
- Tests clean up data after each test run
- Tests create test users with proper password hashing
- Tests verify authentication and authorization
