# Block Testing for AEM Edge Delivery Services Analyze custom AEM Edge Delivery Services block JavaScript and CSS source code for defects, anti-patterns, and standards violations. Produces a structured test plan covering static analysis findings, accessibility compliance, performance characteristics, and manual/automated test scenarios. Helps teams ship blocks that work correctly across devices, browsers, and content variations. ## External Content Safety This skill fetches external web pages for analysis.
