AWS: Fake credentials

For some tests, credentials are used at some point. Instead of using actual credentials, it might be best to use fake credentials depending on the use case.

How to

To mock AWS credentials, you can do something like the following:

conftest.py

import pytest

@pytest.fixture(scope="module", autouse=True)
def aws_fake_credentials():
    import os

    os.environ["AWS_SHARED_CREDENTIALS_FILE"] = "path/to/credentials/file"
    os.environ["AWS_DEFAULT_REGION"] = "eu-north-1"

By writing it as a PyTest fixture, it can be re-used easily throughout your test suite. The default region is set for enhanced default behavior.

The fake credentials file (no extension should be used for this file!) could then be something like this:

fake_aws_credentials

[fake]
aws_access_key_id = fake_key_id
aws_secret_access_key = fake_key_secret
