pytest-databases SKILL.md skillA

pytest-databases from litestar-org/litestar-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add litestar-org/litestar-skills/pytest-databases@git:20261104.3c5d082

Pins git:20261104.3c5d082 in mdr.lock. Pin the fingerprint instead.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# pytest-databases

`pytest-databases` provides session-scoped, container-backed service fixtures.
This guidance targets the immutable `v0.19.0` tag. Load only the plugin modules
the test suite uses. Consume a ready client fixture where one exists; otherwise
connect with the client already used by the project.

## Code Style Rules

- Keep database I/O consistent with the project driver. The package's
  PostgreSQL connection fixtures use synchronous `psycopg`; do not `await`
  their methods.
- Type service fixtures with the service class from the same plugin module.
- Prefer ready client fixtures when provided. For service-only plugins, build
  the project's existing client from the service object's host, port, and
  credentials.
- Keep plugin declarations in the nearest `conftest.py`; do not load every
  backend globally.

## Quick Reference

### Install and enable

```bash
pip install "pytest-databases[postgres]"
```

In `conftest.py`:

```python
pytest_plugins = ["pytest_databases.docker.postgres"]
```

The core `pytest_databases` pytest entry point supplies `docker_client` and
`docker_service`. Each database module supplies its own fixtures.

How to install

The exact contents, by fingerprint

mdr add litestar-org/litestar-skills/pytest-databases@sha256:9fba6b8025189e13

The line at the top of this page pins the label git:20261104.3c5d082, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
