Identify the web-delivery path
Course pages, images and scripts are common HTTP resources. Live media, whiteboards and classroom signaling may use other protocols or platforms. Website onboarding does not prove that every live stream uses the same delivery path.
Keep learner state private
Purchased courses, progress, results and assignments belong to individual accounts. Check cache controls and authorization. The application must validate access and link expiry even when the underlying file is shared.
Prioritize class-start operations
A scheduled class can trigger simultaneous sign-ins, lists and join requests. Test concurrency and external dependencies, and avoid retries that amplify pressure. Check assignment size, timeouts and recovery messages for uploads.
Validate the student journey
Test teacher and student permissions, class entry, reconnection and submission results. Where WebSocket is used, select a supported plan and validate heartbeats and idle connections.
