Adopting Testcontainers for local development

Local development and testing are significant for engineers who wish to ship confidently onto production environments. Test-driven development (TDD) has been adopted as an essential practice to enforce that and ensure that every code change is validated locally and on CI. This is where we arrive at the Testcontainers libraries that support your tests, providing lightweight, ephemeral instances of common databases, message brokers, web browsers, or anything else that can run in a Docker container. With Testcontainers, available in different popular languages: Java, Go, .NET, JavaScript/Typescript, and Python, you can replicate the production environment on your local machine and test everything (including AWS APIs powered by LocalStack)! Testcontainers ensure that the data access layer, user interface, and application are tested well at each step. In this session, we have looked at Testcontainers and how to adopt them to develop our applications locally and run our integration tests while using LocalStack to provision cloud resources inside a Docker container before pushing your application to production! In the end, we have also discussed how LocalStack and the Java version of Testcontainers play nicely with each other and wind up with updates about the all-new LocalStack release!

Accelerate your cloud development with Cloud Pods and LocalStack

Cloud pods are persistent state snapshots of your LocalStack instance that can easily be stored, versioned, shared, and restored. Cloud Pods can be used for various purposes, such as:• Save and manage snapshots of active LocalStack instances.• Share state snapshots with your team to debug collectively.• Automate your testing pipelines by pre-seeding CI environments.• Create reproducible development and testing environments locally.In this session from LocalStack Community Meetup July '24, Bart Szydlowski explores how to use Cloud Pods to accelerate your cloud development & testing. He showcases how you can get started with Cloud Pods, integrate them into your testing pipelines, and make it easy for your team members to be onboarded to your cloud infrastructure — running all on your local machine!Docs: https://docs.localstack.cloud/user-guide/state-management/cloud-pods/
