Amazon-Aws

Designing and implementing applications that make use of Amazon Web Services such as S3, SQS and SimpleDB, require extensive testing to ensure a robust integration. In addition to scenarios for the “happy flows”, test scenarios should be created to handle the critical exceptional situations. How does my application respond to failures in communication, checksum errors, service unavailability, never ending transactions and extremely frequent or heavy traffic? In the spirit of test driven development, I see a need for writing up such scenarios and simulate the unexpected behavior of AWS just to verify the correct handling of each exceptional event.
