partest

Methodology-driven API (and optional UI) autotest harness for Python, with OpenAPI coverage that measures whether the right test cases exist — not just whether an endpoint was called.

pip install partest
pip install 'partest[ui]'     # + Playwright and Pillow for UI suites

What you get

ApiClient — async HTTP for suites: JSON, form, files, raw content=, multi-status expectations, GraphQL, and rich status-mismatch errors.
Coverage by methodology — every operation is classified into a method subtype, and each subtype has a required set of test cases. The report tells you which cases are missing.
partest-gen — scaffold a runnable pytest monorepo suite straight from an OpenAPI file.
Reporting — check_* helpers, Allure steps and attaches (Allure is a soft dependency), interactive HTML coverage, coverage.json, compare / badge / stub CLI.
Auth, tracking, security — OIDC TokenManager with injected credentials, created-resource tracking with LIFO cleanup, SecHttp raw transport, JWT tampering sets, RiskProfile.
UI extra — BasePage, PageMonitor, storage helpers, visual comparison, baseline capture.

A first test

from partest import ApiClient, TypesTestCases
from partest.zorro_report import zorro

types = TypesTestCases

async def test_get_item(api_client):
    """Item is returned by id."""
    await api_client.make_request(
        "GET",
        "/items/{id}",
        add_url1="/1",
        defining_url="/items/{id}",       # OpenAPI template — this is what coverage matches
        expected_status_code=200,
        validate_model=ItemValidation,
        type=types.request_default,       # explicit type beats inference
    )

def test_zorro():
    report = zorro()                      # Allure summary + coverage HTML
    # report.endpoints[*].missing_p1 → your backlog for the next test cases

Scaffold a whole suite

partest-gen from-openapi ./my-suite --file openapi.yaml --depth p1 --with-ui
partest-gen sync-openapi ./my-suite --depth p1     # after the spec changes

--depth resources emits paths and collections, default adds payloads, validators and the first tests, p1 adds the full priority-one stub matrix plus a checklist per tag.

Documentation

Source, issues and the full documentation wiki: https://github.com/Dec01/partest

The user-facing pages also ship inside the package, so they are readable next to your installed copy without a trip to the browser:

python -m partest.docs list                  # what is available
python -m partest.docs show howto-quickstart # read a page
python -m partest.docs path                  # where the files live

Included: quickstart, migration notes, the coverage methodology, permissions, upload testing, reporting, security, UI, recipes, layers, and enterprise notes (shared client, retries, redaction, xdist). The decisions behind them — why coverage is scored this way, what stays in your project — live in the repository, not the wheel.

Or from Python:

from partest.docs import list_docs, read_doc
print(read_doc("concepts-methodology.md"))

Requirements

Python 3.10+. Core dependencies: httpx, pydantic, pyyaml, pytest, pytest-asyncio, allure-pytest, requests, python-dotenv, Faker, matplotlib. The ui extra adds playwright and Pillow.

The bundled pytest plugin loads automatically and enriches Allure titles. Turn it off with PARTEST_PYTEST_PLUGIN=0, pytest_plugin = False in confpartest.py, or pytest -p no:partest if your project already owns Allure hooks.
