Serverless development can speed up your development process a lot by moving infrastructure responsibilities over to cloud providers. However, when testing your application, it can be a challenge to mimic all the cloud services you’re relying on.

One useful tool to help do this when you’re writing Python code is moto. In this post, I’ll show you how to use the moto module in combination with pytest to help test your Python code when it interacts with AWS services like DynamoDB, S3 and others.

I recently created a project aimed at collecting the stories of people impacted by the COVID-19 pandemic called Voices of COVID. This project is designed to collect audio stories from people impacted by the pandemic and make them searchable. For more about the motivation behind it you can review this post.

But I want to make sure that you feel that way too.

This is project 15 in my Twenty Projects in Twenty Days series! This time, we’re looking at how to create an AWS HTTP API with Python. This will be the Python version of yesterday’s project where we created a Surveys service API to track three entities - customers, customer surveys, and survey responses. Let’s get started!
