🚀 Features Implemented

Interactive Test Runner

File: run_tests.sh (412 lines)

Features:

  • ✅ Color-coded TUI with ANSI escape codes
  • ✅ Auto-detects environment (host vs Docker container)
  • ✅ 7 menu options covering all test scenarios
  • ✅ Auto-installs pytest dependencies
  • ✅ Progress indicators and spinners
  • ✅ Error handling with helpful messages
  • ✅ Smart defaults based on environment

Menu Options:

  1. Integration Tests (Bind Mount) - Standard mode
  2. Integration Tests (Docker Volume) - DinD mode
  3. Docker Startup Tests - Container health
  4. All Tests - Complete suite
  5. Quick Test - 30-second verification
  6. Custom Selection - Advanced users
  7. Info & Status - Environment details

Dual-Mode Architecture

Technology: Environment variable toggle

Implementation:

  • USE_DOCKER_VOLUMES=false (default) - Bind mount mode for CI
  • USE_DOCKER_VOLUMES=true - Docker volume mode for dev containers
  • Automatic conditional fixture loading
  • Zero conflicts between modes

Benefits:

  • ✅ CI tests unaffected (25/25 passing preserved)
  • ✅ Dev container testing enabled (19/20 passing)
  • ✅ Transparent to test code (helper functions abstract differences)
  • ✅ Explicit choice (no auto-detection surprises)

Docker Volume Support

Files: tests/conftest_volumes.py (VolumeHelper + VolumePath classes)

Features:

  • ✅ Full Path-compatible API
  • ✅ File operations via docker cp
  • ✅ Directory listing and glob patterns
  • ✅ Database extraction for SQLite access
  • ✅ Smart container readiness detection (~12s vs 60s)
  • ✅ Automatic cleanup

API:

# File operations
volume.copy_to(src_path)
volume.copy_from(src_name, dest_path)
volume.file_exists(filename)

# Directory operations
volume.list_files(pattern)
volume.iterdir()
volume.glob(pattern)
subfolder = volume / "subdir"

# Database access
db_path = volume.read_to_temp("cwa.db")
