pytest fixtures for AWS services, with support for asyncio fixtures using aiobotocore


  • This package is work in progress, it is not recommended for production purposes. During the initial phases of this project, it is likely that some releases could introduce breaking changes in test fixtures. It's highly recommended pinning this dependency to patch releases during the 0.x.y releases.
  • This package could restrict available versions of aws libs, including: aiobotocore, botocore, boto3, and moto.
  • The fixtures in this package might not be optimized for concurrent testing. It is not known yet whether the fixtures are thread safe or adequately randomized to support parallel test suites.


You can install "pytest-aiomoto" via pip

$ pip install pytest-aiomoto


To list the available fixtures

$ pytest --fixtures

This project attempts to provide some common fixtures for commonly used services. As such, it is not a generic package for any services; the moto project provides that and this project builds on that. This project aims to create some useful fixtures that behave nearly the same way for both synchronous clients (botocore) and asynchronous clients (aiobotocore).


Contributions are welcome, if you build similar common fixtures or build on the existing package fixtures. The details for bug fixes could be complicated, due to the dependencies on aiobotocore and moto.

Please review github collaboration practices. Once you clone your fork of the repository:

cd pytest-aiomoto
make init
make test

On OSX, use gmake from Homebrew to get GNU make > 4.x.

It's recommended that development use python 3.8, to avoid introducing any python code that might not be compatible with the minimum version of python supported. This is important in the context of the general evolution of asyncio in python.

Most development is done in a linux context (e.g. Ubuntu LTS). If some development tools or common practices are not working as expected on OSX or Windows, there is limited support for adapting to various development environments.

Tests are run with pytest, please ensure the percentage of coverage at least stays the same before you submit a pull request. The expectation for contributions might be a slow process, please do not anticipate any turn around on the order of days (unless you're already a core contributor). Using your own fork can be a faster way to evolve your fixtures for your use cases.

Release Versions

Install pipx and use it to install versionner.

pipx install versionner
ver --help

With pipx and versionner installed, it can be used to manage releases for any python library. See the documentation for ver for details on how to manage sem-ver library releases. See .versionner.rc file for details of the project configuration.


If you encounter any problems, please file an issue along with a detailed description.
