`encodeAuthorizePayment` and `encodeChargePayment` functions to pass individual parameters instead of a struct. - Updated tests to reflect changes in parameter handling and added edge case scenarios for payment processing. - Adjusted network configurations in tests to use the Sepolia testnet. - Enhanced error handling for unsupported networks and invalid payment references in tests. ---

6/8] test(payment-processor, smart-contracts): enhance payment encoding tests and event assertions - Added comprehensive tests for encoding functions in `erc20-commerce-escrow-wrapper` to verify function selectors and parameter inclusion. - Improved event assertions in `ERC20CommerceEscrowWrapper` tests to check emitted events with exact values for payment authorization, capture, voiding, charging, and reclaiming payments. - Validated function signatures and parameter types across various payment functions to ensure expected behavior. --- .../erc20-commerce-escrow-wrapper.test.ts | 260
