pytest-chalice

A set of py.test fixtures for AWS Chalice

Features

• 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

Requirements

• pytest
• Chalice

Installation

You can install "pytest-chalice" via pip from PyPI:

$ pip install pytest-chalice

Usage

from chalice import Chalice

app = Chalice(__name__)


@app.route('/')
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 conftest.py:

import pytest

from chalice import Chalice

from project.app import app as chalice_app


@pytest.fixture
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'}
