Testing BPM Task Candidate Post Strategy Implementation in RuoYi-Vue-Pro

A comprehensive unit test suite for BPM task candidate post strategy in the RuoYi Vue Pro framework, focusing on user calculation logic based on post IDs.

Test Coverage Overview

This test suite focuses on validating the BpmTaskCandidatePostStrategy implementation, specifically testing user calculation based on post IDs.

Key areas covered include:

Post-based user calculation logic
Integration with PostApi and AdminUserApi services
Parameter parsing and validation
User ID set transformation and verification

Implementation Analysis

The testing approach utilizes Mockito for dependency injection and behavior simulation, ensuring isolated unit testing of the strategy component.

Notable patterns include:

Mock injection for external service dependencies
Data transformation testing with CollectionUtils
Assertion-based verification using JUnit Jupiter

Technical Details

Testing infrastructure includes:

JUnit Jupiter test framework
Mockito mocking framework
BaseMockitoUnitTest extension
Custom utility classes for collection handling
DTO objects for user response handling

Best Practices Demonstrated

The test suite exemplifies several testing best practices:

Clear test method naming conventions
Proper setup of mock objects and dependencies
Isolated test scenarios
Explicit parameter preparation and assertion
Clean separation of concerns between test phases
