Refactor sandbox page update use case with repository factory, observers, and update strategies

[loka1]

📝 Description

Implemented a Wiki Page Update Task using Clean Architecture and multiple design patterns. This implementation provides a flexible, maintainable, and testable solution for updating wiki pages with proper separation of concerns.

Type of Change

• ✨ New feature (non-breaking change that adds functionality)
• 🎨 Code style update (Clean Architecture implementation)
• 🧪 Test update (Comprehensive test suite)
• 📚 Documentation update

Changes Made

1. Core Implementation:

   • Created Clean Architecture structure:

     tasks/sandbox/
     ├── entities/
     │   └── page_entity.py          # Core business entity
     ├── repositories/
     │   ├── repository_factory.py    # Factory for repositories
     │   └── pywikibot_repository.py  # Concrete implementation
     ├── use_cases/
     │   ├── update_page_use_case.py # Business logic
     │   └── update_strategies.py     # Update strategies
     └── observers/
         └── page_update_observer.py  # Logging observers
     

2. Design Patterns Implementation:

   • Factory Pattern: For repository creation
   • Strategy Pattern: For different update methods (Replace/Append/Prepend)
   • Observer Pattern: For logging and monitoring
   • Command Pattern: For page update operations

3. Testing Infrastructure:

   • Added comprehensive test suite
   • Implemented GitHub Actions for CI/CD
   • Added coverage reporting

Design Patterns Used/Modified

• Factory Pattern

  # Repository creation using factory
  repository = RepositoryFactory.create_repository(RepositoryType.PYWIKIBOT)

• Strategy Pattern

  # Different update strategies
  use_case.set_strategy(ReplaceContentStrategy())
  use_case.set_strategy(AppendContentStrategy())
  use_case.set_strategy(PrependContentStrategy())

• Observer Pattern

  # Logging observers
  use_case.add_observer(ConsoleLogger())
  use_case.add_observer(FileLogger("updates.log"))

• Command Pattern

  # Use case as command
  use_case.execute(page_entity)

Test Coverage

• Unit Tests Added/Updated
• Integration Tests Added/Updated
• Pattern Tests Added/Updated
• Test Coverage Maintained/Improved

Test Details

# Test Coverage by Component

- Strategies: 100%

Key Features

1. Clean Architecture Benefits:

   • Clear separation of concerns
   • Easy to test and maintain
   • Framework independent
   • Highly cohesive, loosely coupled

2. Design Pattern Benefits:

   • Flexible update strategies
   • Extensible logging system
   • Easy to add new repositories
   • Clear dependency management

3. Testing Benefits:

   • Comprehensive test coverage
   • Automated CI/CD

Usage Example

# Create repository and use case
repository = RepositoryFactory.create_repository(RepositoryType.PYWIKIBOT)
use_case = UpdatePageUseCase(repository)

# Add logging
use_case.add_observer(ConsoleLogger())
use_case.add_observer(FileLogger("updates.log"))

# Set update strategy
use_case.set_strategy(ReplaceContentStrategy())

# Create and execute update
page = PageEntity(
    title="Page Title",
    text="New content",
    summary="Update summary"
)
use_case.execute(page)
