Testing integrations between services is crucial, particularly for serverless applications like AWS Lambda, due to their distributed and fragmented architecture. Simulator tools like LocalStack can facilitate testing but may yield [[False positives and false negatives|false positives]] because they may diverge from actual AWS services. <ref>{{Cite book |last=Stojanovic |first=Slobodan |title=Serverless Applications with Node.js Using AWS Lambda and Claudia.js |publisher=Manning |isbn=9781638356172}}</ref>
To address this limitation, Yan Cui introduced "remocal testing," enabling local execution of application code while interacting with genuine AWS services. This approach allows real-time debugging and rapid code modifications without deployment. However, it necessitates provisioning and subsequent decommissioning of AWS resources, requiring meticulous planning. <ref name=":1" />
