Fakecloud Launches Local AWS Emulator for Integration Testing with 100% Conformance
Key points
- Fakecloud provides a local AWS emulator for integration tests.
- It supports 105 AWS services and 7,508 operations with 100% conformance.
- Applications use standard AWS SDKs, CLI, and IaC tools against the local environment.
- Fakecloud SDKs offer deeper visibility and control for testing scenarios.
Local AWS Emulation for Development
Fakecloud has launched a local AWS cloud emulator specifically for integration testing. This tool allows developers to run their applications against a local AWS environment, using the same AWS SDKs, CLI, and Infrastructure as Code (IaC) tools they would use with the actual AWS cloud. The emulator aims to provide a fully local development experience.
Comprehensive Service Support and Conformance
The Fakecloud emulator supports 105 AWS services and 7,508 operations, demonstrating 100% conformance. This level of conformance is validated by 248,557 Smithy-model-generated test variants passing on every commit, along with end-to-end tests against official AWS SDKs. It also includes over 30 service-to-service integrations, such as S3 notifications, SNS fanout, and EventBridge targets, to simulate real-world interactions.
Simplified Testing Workflow
Unlike some existing local AWS setups, Fakecloud does not require an AWS account, authentication token, or a paid plan for core development flows. Developers can run a single binary or Docker image and use dummy credentials. Additionally, Fakecloud offers SDKs for TypeScript, Python, Go, PHP, Java, and Rust, which wrap specific endpoints for resets, assertions, and manual control of asynchronous processors during testing.
Impact on AWS Development
This release is significant for developers building applications on AWS, as it provides a robust and comprehensive local testing environment. By enabling full local execution and testing of AWS-dependent applications, Fakecloud can reduce reliance on cloud resources during development, potentially speeding up iteration cycles and simplifying the testing of complex integrations. The high level of API conformance ensures that local tests accurately reflect behavior in the actual AWS environment.

Reporting from
Fakecloud released a local AWS cloud emulator designed for integration tests, allowing applications to interact with a local AWS environment using standard AWS SDKs, CLI, and IaC tools. This tool provides 100% conformance with 105 AWS services and 7,508 operations, enabling developers to test applications locally without requiring AWS accounts or tokens. It matters because it simplifies local development and testing workflows for applications that rely heavily on AWS services, offering deeper visibility and control during testing.
