pytest-probatio
Use a probatio schema as a pytest assertion
matcher. A schema reads as the expected shape, and a mismatch is explained by
probatio's path-precise errors instead of a bare assert.
from pytest_probatio import Exact, Partial
from probatio import Port
def test_response(response):
# Exact: extra keys make it unequal.
assert response == Exact({"name": str, "port": Port()})
# Partial: extra keys are allowed.
assert response == Partial({"name": str})
assert Exact({"name": str}) <= response
When the data does not match, the failure lists each error by its path:
data does not match the probatio schema (==):
port: expected a port number between 1 and 65535
Install it alongside pytest; the plugin registers itself:
pip install pytest-probatio
This package lives in the probatio monorepo but ships separately, so the core
probatio library stays dependency-free.
The full guide, including schema reuse across tests and the raises helper,
lives at
probatio.frenck.dev.
