Pull request overview

This PR updates the Quantum extension’s live e2e “submit” job tests to validate SAS URI behavior more accurately, including differentiating user delegation SAS vs service SAS when storage shared key access is toggled.

Changes:

• Refactors SAS substring assertions into helper assertion methods for reuse.
• Extends test_submit_with_disabled_then_enabled_storage_key_access to validate user delegation SAS parameters when shared key access is disabled, and absence of those parameters after re-enabling.
• Adjusts wait timing between toggling shared key access and subsequent validation.
