Block outbound TCP connections from an AWS Lambda function to one or more target hostnames for a configurable duration so you can test how the function behaves when a TCP-based dependency is unreachable.

Delete one or more event source mappings on an AWS Lambda function for a configurable duration and recreate them afterwards so you can test how the workload behaves when the function stops receiving events from its source.

Delete the reserved concurrency configuration on an AWS Lambda function for a configurable duration and restore it afterwards so you can test how the workload behaves when the function has to share account-level concurrency with other functions.

Detach a specified Lambda layer from a target AWS Lambda function for a configurable duration and reattach it afterwards so you can test how the workload behaves when a shared dependency layer disappears.

Inject runtime latency into an AWS Lambda function for a configurable duration so you can test how upstream callers and downstream consumers handle slower-than-expected responses, cold-start spikes, and resource contention.

Override the HTTP status code returned by an AWS Lambda function for a configurable duration so you can test how upstream callers and downstream consumers handle unexpected error status responses.

Override the response body returned by an AWS Lambda function for a configurable duration so you can test how upstream callers and client applications handle unexpected payload shapes and corrupted data.

Disable one or more event source mappings on an AWS Lambda function for a configurable duration and re-enable them afterwards so you can test how the workload behaves when the function temporarily stops receiving events from its source.

Lower the memory allocation of an AWS Lambda function for a configurable duration and restore it afterwards so you can test how the workload behaves with less memory and a proportionally smaller CPU share.

Lower the configured timeout of an AWS Lambda function for a configurable duration and restore it afterwards so you can test how the workload behaves when invocations are cut short.

Detach a specified IAM policy from the execution role attached to an AWS Lambda function for a configurable duration and reattach it afterwards so you can test how the workload behaves when the function loses permission to call a downstream AWS service.
