orb create provisioning --cpu 4 --memory 8192
```

**Docker connection failed**:
```bash
orb restart provisioning
docker -H /var/run/docker.sock ps
```

**Service health check timeout**:
```bash
# Check logs
nu provisioning/tests/integration/framework/orbstack_helpers.nu orbstack-logs orchestrator

# Increase timeout in test_config.yaml
# test_execution.timeouts.test_timeout_seconds: 600
```

**Test environment cleanup failed**:
```bash
# Manual cleanup
nu provisioning/tests/integration/teardown_test_environment.nu --force
```

## Contributing

### Writing New Tests

1. **Choose appropriate directory**: `modes/`, `services/`, `workflows/`, `e2e/`, `performance/`, `security/`
2. **Follow naming convention**: `test_<feature>_<category>.nu`
3. **Use test helpers**: Import from `framework/test_helpers.nu`
4. **Add assertions**: Use `assert-*` helpers
5. **Cleanup resources**: Always cleanup, even on failure
6. **Update coverage**: Add test to TEST_COVERAGE.md

### Example Test

```nushell
use std log
use ../framework/test_helpers.nu *

def test-my-feature [test_config: record] {
    run-test "my-feature-test" {
        log info "Testing my feature..."

        # Setup
        let resource = create-test-resource

        # Test
        let result = perform-operation $resource

        # Assert
        assert-eq $result.status "success"

        # Cleanup
        cleanup-test-resource $resource

        log info "✓ My feature works"
    }
}
```
