Story 0.2.3: E2E & Cross-Platform Testing

Epic: 0 (Demo Infrastructure)
Priority: MEDIUM
Dependencies: Stories 0.2.1 (Core) and 0.2.2 (Visual Testing)
Platform Focus: Full cross-platform support (Windows, macOS, Linux) with comprehensive E2E testing

Story Overview

As a developer working on AcoustiCalc, I want comprehensive end-to-end testing with full cross-platform validation and terminal recording, so that I can ensure complete application functionality works consistently across all supported platforms through CI-based testing with visual evidence.

Acceptance Criteria

1. End-to-End Test Framework

• Given complete application workflows exist
• When E2E tests execute
• Then full user journeys are tested from start to finish with automated validation

2. Cross-Platform CI Matrix

• Given E2E tests work on development systems
• When tests run through GitHub Actions
• Then all platforms (Ubuntu, macOS, Windows) validate consistent behavior

3. Terminal Recording Integration

• Given E2E tests are executing
• When user interactions occur
• Then terminal sessions are recorded with input visualization, output capture, and demo-ready format generation

4. Platform-Specific Testing

• Given different operating systems have unique characteristics
• When E2E tests run
• Then platform-specific behaviors and edge cases are validated

5. Comprehensive Test Reporting

• Given E2E tests complete across all platforms
• When results are aggregated
• Then comprehensive cross-platform test reports with visual evidence are generated

Technical Implementation Overview

Foundation Built On Stories 0.2.1/0.2.2

• ✅ Visual Testing Infrastructure: Cross-platform screenshot capture working with robotgo library
• ✅ Artifact Management System: Command-line artifact manager with indexing, cleanup, export capabilities
• ✅ Cross-Platform Compatibility: PNG/sRGB format standardization, platform optimizations
• ✅ Performance Optimization: Screenshot capture ~1.06s, CI overhead <30s constraint met
• ✅ Quality Achievement: 78.4% test coverage, 47 test cases ALL PASSING, 318 artifacts generated

Key Implementation Areas

E2E Test Framework (tests/e2e/)

• Complete application workflow test scenarios
• TUI interaction testing with mouse and keyboard
• Audio feedback testing preparation
• Error handling and recovery scenario tests
• Performance and responsiveness testing

Cross-Platform CI Implementation

• Comprehensive GitHub Actions matrix testing
• Platform-specific configurations and workarounds
• Windows/macOS/Linux specific validation
• Cross-platform behavior consistency validation

Terminal Recording System (tests/recording/)

• Cross-platform terminal recording utilities
• Input visualization overlay systems
• Audio synchronization preparation
• Recording compression and optimization
• Integration with E2E test execution

Test Reporting (tests/reporting/)

• Cross-platform test result aggregation
• Visual test result dashboards and reports
• Platform comparison and consistency analysis
• Visual evidence integration with screenshots/recordings

Technology Stack Extensions

• New Dependencies: github.com/asciinema/asciinema (terminal recording)
• External Tools: ffmpeg, asciinema, xdotool/xclip (Linux), screencapture (macOS), PowerShell (Windows)
• CI Platform: GitHub Actions comprehensive matrix (ubuntu-latest, macos-latest, windows-latest)

Developer Handoff Information

For External Development Agents

Prerequisites

• Review Stories 0.2.1 and 0.2.2 completion (foundation dependencies)
• Read technical architecture: docs/architecture/coding-standards.md, docs/architecture/tech-stack.md, docs/architecture/source-tree.md
• Understand existing test infrastructure in tests/visual/, tests/artifacts/, tests/scripts/

Implementation Approach

1. GitHub Setup: Issue Story 0.2.3: E2E & Cross-Platform Testing #34 created, feature branch feature/story-0.2.3-e2e-cross-platform-testing ready
2. Development Pattern: Follow enterprise-grade patterns established in Story 0.2.2 (Strategy pattern, Observer pattern, thread-safe operations)
3. Quality Gates: >95% test coverage target, <30s CI overhead constraint, all platforms must pass
4. Integration Points: Build on existing tests/visual/visual_utils.go and tests/scripts/artifact_manager.go

Key Implementation Tasks (47 subtasks total)

• E2E Test Infrastructure: Directory structure, workflow scenarios, orchestration framework
• Cross-Platform CI: GitHub Actions matrix enhancement, platform-specific validations
• Terminal Recording: Cross-platform utilities, input visualization, recording integration
• Test Reporting: Result aggregation, visual dashboards, platform comparison

Critical Success Factors

• Leverage existing Story 0.2.2 infrastructure (don't rebuild, extend)
• Maintain performance constraints (<30s CI overhead)
• Ensure cross-platform consistency
• Follow established coding standards and patterns
• Comprehensive test coverage with visual evidence

Repository Context

• Main Branch: main
• Feature Branch: feature/story-0.2.3-e2e-cross-platform-testing
• Story File: docs/stories/0.2.3.story.md (authoritative requirements)
• Working Directory: /Users/dzmitrymisiuk/src/ai/acousticalc
