pytest-chronicle 0.2.1

Reusable pytest results ingestion tooling with database export and CLI helpers.

pytest-chronicle

Traceable pytest history: capture results, ingest into SQLite or Postgres, and answer “when did this test last go red?” or “which commit flipped it green?”.

What it does

• Pytest plugin emits per-test JSONL records (stdout/stderr/traceback included).
• Ingestion stamps runs with git/CI metadata and writes to SQLite or Postgres.
• CLI queries last failures, error details, flip-to-green commits, and branch/commit diffs with pytest-like selectors.

Install

uv pip install pytest-chronicle

Quickstart

pytest-chronicle init --project my-project --suite pytest          # create config + local sqlite
pytest -q                                                           # auto-ingests using config/env/fallback SQLite
pytest-chronicle query last-red --format json --pretty             # ask questions

Common commands

• pytest-chronicle init – scaffold .pytest-chronicle.toml and an async SQLite DB.
• pytest-chronicle ingest --jsonl <path> – ingest JSONL/summary artifacts.
• pytest-chronicle query last-red|errors|flipped-green|compare – history lookups (-k/-m like pytest).
• pytest-chronicle run <project> -- <pytest args> – run pytest under uv, collect artifacts, optionally ingest.
• pytest-chronicle backfill – ingest many summary.json files.
• pytest-chronicle export-sqlite / import-sqlite – migrate between backends.
• pytest-chronicle db upgrade – apply Alembic migrations.
• pytest-chronicle config show|set – view or set repo defaults.

Configuration & defaults

• Precedence: CLI flag --database-url > env (PYTEST_RESULTS_DB_URL, legacy TEST_RESULTS_DATABASE_URL / SCS_DATABASE_URL) > .pytest-chronicle.toml > fallback SQLite at <repo>/.pytest-chronicle/chronicle.db (async).
• Example config:

  [chronicle]
  database_url = "postgresql+asyncpg://user:pass@host/db"
  project = "my-project"
  suite = "pytest"
  

• Typical flow: use SQLite for local dev (via init); point env or config at Postgres for CI/prod. No other changes needed.

Pytest plugin (auto ingestion)

• Install the package; the pytest_chronicle plugin is auto-discovered.
• If a database is configured via env/config (or fallback SQLite), the plugin will ingest automatically at session end. You can still pass --chronicle-db <url> to override, or --chronicle-no-ingest to skip.
• Default JSONL path: .artifacts/test-results/chronicle-results.jsonl (created automatically).
