You’ve been there: Your Unit tests pass both locally and in CI. You deploy with confidence. You thought.. Then staging in the real cloud reveals the truth—bugs that only show up with actual RDS parameter settings, real SQS and SNS throughput limits, or Lambda and API Gateway behaviour your local mocks never captured.
The solution is Testcontainers.
Testcontainers is a testing library that provides easy and lightweight APIs for bootstrapping integration tests with real services wrapped in Docker containers. Using Testcontainers, you can write tests talking to the same type of services you use in production without mocks or in-memory services. Spin them up, run migrations, execute your Node.js service against them, assert results, auto-cleanup.

In this talk, Teja explore the intricacies of the software supply chain and discuss strategies for protecting your software against supply chain attacks. He look sinto the risks associated with these threats, offer mitigation measures, and covers recommended practices for managing open-source software and Software Bills of Materials (SBOMs). This session aims to equip the audience with the knowledge and tools needed to enhance the security of their software supply chain.

Cloud pods are persistent state snapshots of your LocalStack instance that can easily be stored, versioned, shared, and restored. They can be used to 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, and 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!

In this session, Maximillian Hoheiser discussed developing & testing AWS Data Streaming with LocalStack! In this talk, he focused on Kinesis Data Firehose, an AWS service that allows you to extract, transform, and load streaming data into various destinations like Amazon S3. He dived into how to set up testing for Kinesis Firehose and seamlessly integrated it with other services using Boto3 and CDK/CloudFormation. Maximillian led a live demonstration, showcasing how to set up a practical business case, implement it, and rigorously test it using LocalStack.
