Preface

In general, AWS services can be accessed using

1. AWS web interface,
2. API libraries in a programming language, such as boto3 for Python 3,
3. AWS command-line interface, i.e. awscli.

I opted for the API library since it is

Using py.test is great and the support for test fixtures is pretty awesome. However, in order to share your fixtures across your entire module, py.test suggests you define all your fixtures within one single conftest.py file. This is impractical if you have a large quantity of fixtures -- for better organization and readibility, you would much rather define your fixtures across multiple, well-named files. But how do you do that? ...No one on the internet seemed to know.

Turns out, however, you can define fixtures in individual files like this:

tests/fixtures/add.py

import pytest

@pytest.fixture
