Fakecloud: Local AWS cloud emulator for integration tests

原文开头节选

Local AWS cloud emulator for integration tests. Run your app with normal AWS clients, stay fully local, and use fakecloud SDKs when your tests need deeper visibility. 105 services. 7,508 operations. 248,557/248,557 Smithy variants pass — true 100% conformance. Get Started Why fakecloud Why fakecloud? fakecloud gives you a local AWS environment that behaves like infrastructure, not a mock. Your app uses the regular AWS SDK, CLI, and IaC tools. Unlike today’s LocalStack Community setup, you do not need an account, auth token, or paid plan just to keep core development flows local. The SDKs make that workflow nicer, not narrower. Start fakecloud, run the code you actually ship, inspect emails/messages/invocations after the fact, and force async AWS-style behavior to happen on demand. Built for realistic local testing Real APIs for your app, purpose-built tooling for your tests. Workflow Test what your app really does Use normal AWS clients against localhost, then verify the effects with fakecloud instead of stitching together polling, fixtures, or private test hooks.
