A set of py.test fixtures for AWS Chalice


  • Launch the local gateway per test function

  • Provide an abstracted client fixture to access the local gateway

  • Expose an interface to overwrite response context with arbitrary objects
    • As of Chalice version 1.8.0, LocalGateway object doesn’t handle Cognito’s context

    • Not only for this purpose, it’s an interface provided to allow custom contexts in unit tests



You can install “pytest-chalice” via pip from PyPI:

$ pip install pytest-chalice


from chalice import Chalice

app = Chalice(__name__)

def index:
    return {'hello': 'world'}

pytest-chalice expects a fixture called app which will be the chalice app instance from your project. You can create it in your

import pytest

from chalice import Chalice

from import app as chalice_app

def app() -> Chalice:
    return chalice_app
from http import HTTPStatus

def test_index(client):
    response = client.get('/')
    assert response.status_code == HTTPStatus.OK
    assert response.json == {'hello': 'world'}

See examples for more detailed
