# Testing Policy

This repository tests its configuration at defined seams. The tests run with `bats`; run them with `./tests/run.sh` before every push.

## Seams Under Test

| Seam | File | What it asserts |
|------|------|-----------------|
| Compose validity | `tests/compose_validity.bats` | YAML parses, services have images, no named volumes |
| Env consistency | `tests/env_consistency.bats` | every `${VAR}` is defined in `.env.example`; no real secrets; the live gitea password never appears |
| Caddyfile validity | `tests/caddyfile.bats` | per-host Caddyfile, `.local` convention, balanced braces, basic auth present |
| Docs completeness | `tests/docs_completeness.bats` | every compose service has a docs page; index links every page |
| Script syntax | `tests/scripts_syntax.bats` | `bash -n` clean, executable bits, shellcheck when available |
| Deployment flow | `tests/deployment_flow.bats`, `tests/deployment_scoping.bats` | scoped dispatcher exists, targets are known, service plans isolate inference, Caddy ownership is guarded, and SSH reachability is checked (skips offline) |

## Focused pre-commit testing

For normal commits, use the focused wrapper:

```bash
./scripts/test-changed.sh
```

It reads staged paths with `git diff --cached` and runs only the mapped Bats
files. The tracked `.githooks/pre-commit` hook invokes this wrapper. Enable the
repository hook path once per checkout:

```bash
git config core.hooksPath .githooks
```

Use `--list` to inspect the selection without running tests, or `--paths FILE
...` to preview a mapping. Shared test infrastructure and unmapped paths fail
closed rather than silently skipping coverage. Run the full suite with
`./tests/run.sh` when changing shared test helpers, the test runner, or when
focused coverage is not sufficient.

## Red-Green

Tests are written first. A failing test means the seam is not satisfied; the config change that makes it pass is the only acceptable fix. No `--no-verify`, no deleting tests without approval.
