/**
|
||||
* Integration Test: Category Icon Management Use Case Orchestration
|
||||
*
|
||||
* Tests the orchestration logic of category icon-related Use Cases:
|
||||
* - GetCategoryIconsUseCase: Retrieves category icons
|
||||
* - UploadCategoryIconUseCase: Uploads a new category icon
|
||||
* - UpdateCategoryIconUseCase: Updates an existing category icon
|
||||
* - DeleteCategoryIconUseCase: Deletes a category icon
|
||||
* - Validates that Use Cases correctly interact with their Ports (Repositories, Event Publishers)
|
||||
* - Uses In-Memory adapters for fast, deterministic testing
|
||||
*
|
||||
* Focus: Business logic orchestration, NOT UI rendering
