Amazon says no human wrote or reviewed the code for its new cloud testing tool
Summary
Amazon released AWS Emulator, a local tool for testing cloud applications, with implementation code written and reviewed by autonomous AI agents. Separate agents test service fidelity, identify differences from real AWS, and fix issues; changes pass compilation, style, security, and regression checks. Fidelity tests compare workflows against real AWS accounts, but only verify behaviors covered by those tests. AWS warns the emulator does not validate application security, including KMS and S3 policies, and may allow requests that real AWS denies. Developers must test full application behavior and security settings on AWS before production.
