December 2024 performance snapshot: Delivered targeted quality improvements across two repositories. In localstack/localstack, added comprehensive tests for EventBridge Scheduler TagResource/UntagResource APIs, including fixture-based support for creating/deleting schedule groups and tests validating tagging/untagging behavior and resource lifecycle. In localstack/docs, fixed OpenSearch password parsing for special characters to prevent connection errors when passwords are supplied via CLI arguments or environment variables, improving connection reliability. These efforts increase test coverage, reduce risk of misconfigurations, and strengthen integration reliability for customers.
