Validating Trade Price Calculations in RuoYi-Vue-Pro

This test suite validates the pricing calculation functionality in the RuoYi-Vue-Pro trade module, focusing on order price calculations with multiple SKUs, discounts, and promotions. The tests ensure accurate price computations across various scenarios including selected/unselected items and different quantity combinations.

Test Coverage Overview

The test suite provides comprehensive coverage of the TradePriceService implementation, focusing on order price calculations.

Tests order price calculations with multiple SKUs and quantities
Validates price components including total price, discounts, delivery charges, and final payment amount
Covers scenarios with selected and unselected items
Verifies property mapping and SKU details retrieval

Implementation Analysis

The testing approach utilizes Mockito for dependency isolation and JUnit Jupiter for test execution.

Implements mock responses for ProductSkuApi and ProductSpuApi
Uses detailed assertion chains to verify price calculations
Employs BaseMockitoUnitTest for common testing infrastructure
Demonstrates thorough validation of complex object structures

Technical Details

Testing Framework: JUnit Jupiter
Mocking Framework: Mockito
Base Test Class: BaseMockitoUnitTest
Key Dependencies: ProductSkuApi, ProductSpuApi
Test Data: Includes mock SKU and SPU data with properties

Best Practices Demonstrated

The test implementation showcases several testing best practices and patterns.

Comprehensive assertion coverage for all price components
Clear test data setup and mock configuration
Detailed validation of nested object properties
Proper separation of test setup, execution, and verification phases
Well-structured test method with clear sections for setup, mocking, and assertions
