pytest-chronicle 0.3.1

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

pytest-chronicle

Searchable git-aware pytest history with a lean CLI and easy storage backends.

Pin down regressions. Squash bugs. Join the Federation today.

What it does

Running pytest:

• Emits per-test records (result/stdout/stderr/traceback)
• Persists test result records to SQLite / Postgres (or implement your own storage backend) with:
  • git/CI metadata
  • pytest invocation parameters
  • timestamps
  • user-defined labels

With the pytest-chronicle CLI you can now query the test result history.

Install

pip install pytest-chronicle

Quickstart

pytest-chronicle init                                     # create config + local sqlite
pytest -q                                                 # auto-ingests using config/env/fallback SQLite
pytest-chronicle query last-green --format json --pretty    # ask questions
pytest-chronicle query last-red tests/test_mod.py::Test::test_case   # pytest-style selectors

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|last-green|errors|flipped-green|compare – history lookups. Filters: -k/-m like pytest, --labels, --since, --until, --branch/--commit, positional pytest-style selectors, or --pytest-select "-m 'slow' -k expr path::nodeid". Outputs include per-test runtime (time_sec) and git metadata; text mode shows colored tables by default (--no-color to disable).
• pytest-chronicle query timeline – colored TTY timeline of recent runs for matching tests (? marks not-run/filtered cases).
• 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 = "ci-smoke,linux"   # labels/tags (comma-separated)
  

• Typical flow: use SQLite for local dev (via init); point env or config at Postgres for CI/prod. No other changes needed.
• If you skip --project during init, it is auto-detected from pyproject.toml (or the current folder name); the CLI tells you how to change it later.

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).
