"""
Test suite for Phase 3 refactoring of confirm_eskaera().

Tests the 3 helper methods created in Phase 3:
- _validate_confirm_json(): Validates JSON request data
- _process_cart_items(): Processes cart items into sale.order lines
- _build_confirmation_message(): Builds localized confirmation messages

Includes tests for:
- Request validation with various error conditions
- Cart item processing with product context
- Multi-language message building (ES, EU, CA, GL, PT, FR, IT)
- Pickup vs delivery date handling
- Edge cases and error handling
