In software development, it’s common to write functions that interact with cloud services. Instead of testing these functions against the actual cloud services, we can utilize Localstack to create local mock versions of these services. This approach enables us to test our functions without network dependencies and without altering the state of the real cloud services. In this post, we will explore how to use Localstack to test functions that interact with AWS DynamoDB.

Have you ever come across the infamous ‘It works on my machine’ issue? I’m sure you have—it’s a common challenge in software development. To tackle this problem, Docker containers offer a solution by allowing you to encapsulate your code and execute it in a consistent environment. As a result, Docker is widely adopted in various domains, including the automation of CI/CD pipelines. In this article, I will demonstrate how to leverage Docker to create and execute a Python test environment.
