Testing Alipay WAP Payment Integration in RuoYi Vue Pro

This test suite validates the Alipay WAP (H5) payment integration functionality in the RuoYi Vue Pro framework. It focuses on testing the payment order creation and handling of responses from the Alipay API.

Test Coverage Overview

The test suite provides comprehensive coverage of Alipay WAP payment scenarios.

Key areas tested include:

Successful payment order creation with proper parameter mapping
Error handling for failed channel responses
Validation of payment status transitions
Verification of response data transformation

Implementation Analysis

The testing approach utilizes JUnit 5 with Mockito for API simulation. The implementation follows a structured pattern using @BeforeEach for test initialization and @DisplayName for clear test case identification.

Technical patterns include:

Mock response generation for Alipay API calls
Argument matching for request validation
Detailed assertion chains for response verification

Technical Details

Testing infrastructure includes:

JUnit 5 testing framework
Mockito for API mocking
Custom test utilities for random data generation
Alipay SDK integration for request/response handling
AbstractAlipayClientTest as base test class

Best Practices Demonstrated

The test suite exemplifies high-quality testing practices through thorough validation and clean code organization.

Notable practices include:

Comprehensive assertion coverage for response objects
Isolated test cases with clear purpose
Proper mock setup and verification
Detailed error scenario testing
