# Tests

This directory is for smoke tests and validation checks for Atlas infrastructure.

## What Belongs Here

- Smoke tests for installation phases.
- Validation checks for mounts, services, network identity, and repository state.
- Script syntax checks.
- Non-secret test fixtures.

## What Must Not Be Stored Here

- Secrets.
- Real production data.
- SQL backups.
- Large generated test output.
- Package caches.
- Environment-specific local overrides.

## Naming Conventions

- Use lower-case hyphenated names.
- Prefer names that describe the observable behaviour being checked.
- Group tests by area when useful, for example `tests/smoke/`.

## Expected Future Structure

Current planned areas include:

```text
tests/smoke/
```

Additional test groups should be added only when they have clear ownership and purpose.

## Security Considerations

Tests must not expose secrets or mutate production data unless explicitly designed and approved. Prefer read-only validation where practical.
