Add comprehensive unit tests for STS authorization in streaming uploads
Add comprehensive unit tests for STS authorization in streaming uploads
Created test suite to verify that verifyV4Signature properly handles STS identities by falling back to IAM authorization when shouldCheckPermissions is true. Tests cover: - STS identities with IAM integration (allow and deny cases) - STS identities without IAM integration (should deny) - Traditional identities with Actions (canDo check) - Permission check bypass when shouldCheckPermissions=false - Specific streaming upload scenario from bug report - Action determination based on HTTP method All tests pass successfully.pull/7988/head
