LocalStack enables organizations to automate their application testing and integration process through DevOps practices, such as continuous integration (CI). LocalStack allows organizations to move away from complicated AWS testing and staging environments by enabling a key component of testing and delivering cloud-native applications. To further automate the process, we use Infrastructure-as-Code (IaC) frameworks like Terraform that allow you to create your resources declaratively and apply those resources. Testing your Terraform modules against the real AWS cloud can be time-consuming and costly and can make you run into the risk of dangling resources after an unsuccessful CI run. Using LocalStack to emulate a mock ephemeral AWS infrastructure on CI pipelines allows you to work on the same functionality the real AWS cloud provides while cutting down testing costs and deployment times. In this session, Jim Sheldon, Senior Developer Advocate at Harness, will demonstrate how to use LocalStack to test Terraform modules on Harness CI. Harness CI allows you to create software pipelines that will enable you to check out your code, build the software, run your tests, and validate every code change. We wind up the session with updates about the all-new LocalStack release!

Ever wish you could test your whole cloud app without touching the cloud? I’ll show you how to validate your serverless pipeline from start to finish, right on your laptop using LocalStack. Join our Slack community and start shipping with confidence.

In this live session, Brian from LocalStack will demonstrate the WireMock extension for LocalStack, showing how developers can achieve end-to-end local testing by combining AWS service emulation with external API mocking. Brian will walk through real-world use cases, demonstrate the integration in action, and explain how this unified approach simplifies testing complex cloud applications that depend on both AWS services and third-party APIs.

Infrastructure-as-Code refers to the practice of defining and provisioning cloud resources using code and automation scripts, thus eliminating the need for manual configurations. With frameworks like AWS CloudFormation, AWS CDK (Cloud Development Kit), AWS Serverless Application Model (SAM), Pulumi, and Terraform, users can specify their desired infrastructure state in code, enabling rapid and consistent deployment of resources. However, as with any code, IaC scripts require thorough testing to ensure their correctness and proper functionality. Traditional cloud environments for testing can be expensive, slow, and error-prone due to complexities in provisioning and configuration. With LocalStack, you can leverage a local emulation of various cloud services, such as S3, DynamoDB, EKS, and more! LocalStack simulates these cloud services on a developer's machine, allowing for comprehensive and efficient testing of IaC scripts before deployment to actual cloud environments. In this video, we explain how you can use LocalStack to be more efficient and cost-effective at testing these major IaC frameworks: Terraform, Pulumi, Cloud Development Kit, CloudFormation, and Serverless Application Model. As organizations will continue to embrace IaC, cloud emulation framework like LocalStack will play an increasingly vital role in ensuring the quality and robustness of cloud infrastructure implementations.
