Description

The multisig pallet provides multi-signature dispatch functionality, allowing multiple accounts to coordinate and execute calls from a deterministic composite origin.

Objectives

Implement E2E tests covering key multisig pallet flows:

• Multisig Creation: Test as_multi() for multi-step operations with various threshold configurations
  • as_multi_threshold_1() cannot be tested initially, as it is not possible to create a 1-threshold multisignature account in PJS.
• Approval Process: Test approve_as_multi()/as_multi() for adding approvals to existing multisig operations, including threshold validation and signatory ordering
• Execution and Cancellation: Test successful execution when threshold is met and cancel_as_multi() for operation cancellation by the depositor
• Deposit Management: Test poke_deposit() for updating deposit amounts and deposit calculation based on threshold and signatory count
• Edge Cases: Test invalid thresholds, duplicate approvals, wrong timepoints, unauthorized cancellations, and integration with other pallets for actual call execution
