tavern-aws 1.1.0

HTTP plugin for Tavern with AWS4Auth

Tavern AWS plugin

This is a Tavern plugin to add AWS Sig4 authentication headers to your calls using requests-aws4auth .

This plugin reuses original requests-based REST plugin from Tavern, so it works with non-AWS endpoints too.

Usage

Install

Regular install via pip: pip install tavern-aws

Tavern integration

Set option tavern_http_backend to aws.

You can do it via project options:

[tool.pytest.ini_options]
tavern_http_backend = aws

or via conftest.py:

def pytest_configure(config: pytest.Config):
    config.option.tavern_http_backend = "aws"

Change it back to requests to use regular Tavern's REST plugin.

Tests

Supply AWS credentials as text fields:

test_name: Call endpoint with IAM auth

aws:
    access_key: xxxxxxxxxxxxxxxxxxxx
    secret_key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    service: appsync
    region: us-east-1

stages:
  - name: first stage

Or from boto3 session object via pytest fixtures:

import boto3
import botocore.credentials
import pytest

@pytest.fixture(scope="session", autouse=True)
def boto_session() -> boto3.Session:
    return boto3.Session()

@pytest.fixture(scope="session", autouse=True)
def boto_credentials(boto_session: boto3.Session) -> botocore.credentials.Credentials:
    return boto_session.get_credentials()

test_name: Call endpoint with IAM auth

aws:
    access_key: "{boto_credentials.access_key}"
    secret_key: "{boto_credentials.secret_key}"
    service: appsync
    region: us-east-1
    session_token: "{boto_credentials.token}"

stages:
  - name: first stage
