New Test Project Created - -**InfoBoxCore.Tests** -- Framework: NUnit 4.4.0 with FluentAssertions 6.12.0 -- Target: .NET 8.0-windows -- Language: C# 7.3 (for .NET 4.8 compatibility) -- Location: `InfoBoxCore.Tests/` - -### 2. Abstraction Layer (P0.2) - -**Files Created:** -- `InfoBox/Abstractions/ITextMeasurement.cs` - Interface for text measurement operations -- `InfoBox/Implementation/GraphicsTextMeasurement.cs` - Production implementation using Graphics -- `InfoBoxCore.Tests/Mocks/MockTextMeasurement.cs` - Test implementation with configurable measurements - -**Key Benefits:** -- ✅ Tests can run without graphics context -- ✅ Predictable, deterministic text sizing in tests -- ✅ Enables CI/CD on headless servers - -### 3. Presentation Layer (P0.1) - -**Model:** -- `InfoBox/Presentation/InformationBoxModel.cs` - Pure data class with all configuration properties - -**Presenter:** -- `InfoBox/Presentation/InformationBoxPresenter.cs` - Testable business logic extracted from InformationBoxForm - -**Methods Extracted:** -1. **GetButtons()** - Button generation logic (replaced lines 1391-1470 in InformationBoxForm.cs) - - Determines which buttons to display based on InformationBoxButtons enum - - Handles custom button texts (User1, User2, User3) - - Manages help button display logic - - Marks default button - -2. **CalculateLayout()** - Layout calculation logic (extracted from lines 999-1110) - - Calculates required dimensions for text, icons, buttons - - Determines if vertical scrolling is needed - - Handles checkbox width calculations - - Manages multi-monitor scenarios - -3. **UpdateAutoClose()** - Auto-close logic (extracted from lines 1677-1791) - - Manages countdown timer state - - Determines which button to auto-click - - Handles different auto-close modes (Button, TimeOnly, Result) - -**Supporting Classes:** -- `InfoBox/Presentation/LayoutCalculation.cs` - Layout calculation results -- `InfoBox/Presentation/ButtonDefinition.cs` - Button configuration without WinForms dependencies -- `InfoBox/Presentation/AutoCloseState.cs` - Auto-close state without Timer dependencies - -### 4.

Added `InformationBoxPresenter` field (line 92) -3. Initialized `GraphicsTextMeasurement` in constructor (line 307) -4. Created `InitializePresenter()` method to build model and create presenter (lines 610-641) -5. Refactored `SetButtons()` to use presenter (lines 1387-1404) - **Reduced from 89 lines to 17 lines** - -**Result:** -- ✅ Form now uses presenter for button generation -- ✅ Business logic separated from UI -- ✅ Maintains 100% backward compatibility -- ✅ No breaking changes to public API - -### 5.
