Implements Task 18 from phases 7-9 plan. SearchFormViewModel wraps
SearchSection model with properties for MaxResultRows, TimeoutSeconds,
and MaxConcurrentSearches. Includes full test coverage with 7 tests
verifying initialization, two-way binding, change notification, and
null argument handling.
Add service for auto-discovering configuration file locations. The
service searches in prioritized order:
1. JDESCOPING_CONFIG_PATH environment variable
2. Same directory as executable
3. ../JdeScoping.Host/ relative to executable
4. User config directory (~/.jdescoping on Unix, %LOCALAPPDATA%\JdeScoping on Windows)
Includes 9 unit tests covering all search locations, priority order,
edge cases (missing directory, missing appsettings.json), and
cancellation token support.
Add config file loading and saving service following TDD approach:
- IConfigFileService interface for loading/saving config files
- ConfigLoadException for descriptive error handling
- ConfigFileService implementation with JSON serialization
- Unit tests with mocked IFileSystem dependency
Add file system abstraction to enable testability for file operations.
- IFileSystem interface with common file operations
- FileSystem implementation wrapping System.IO
- Unit tests for FileExists functionality
