"""Un-Gameable Functional Tests for Template Discovery CLI Integration

This test suite validates the CLI integration of the Template Discovery Engine
with real command-line workflows that are immune to AI gaming.

TRACEABILITY TO STATUS AND PLAN:
===============================

STATUS Gaps Addressed (STATUS-TEMPLATE-DISCOVERY-EVALUATION-2025-11-17-080057.md):
- Section 2.3: CLI Integration (0% implemented) → All CLI tests

PLAN Items Validated (PLAN-TEMPLATE-DISCOVERY-2025-11-17-080505.md):
- P1-12: Add --recommend Flag (lines 362-384) → test_cli_recommend_flag_basic
- P1-13: Rich Console Output (lines 386-409) → test_cli_recommendation_display_format
- P1-14: Template Selection Flow (lines 411-433) → test_cli_accept_recommendation, test_cli_decline_recommendation
- P1-17: CLI Integration Test (line 503: "--recommend flag works in CLI")

TEST PHILOSOPHY:
================
These tests validate REAL CLI behavior by:
1. Using Click's CliRunner for actual command execution
2. Verifying console output users would see
3. Testing interactive flows (accept/decline)
4. Ensuring backward compatibility (no breaking changes)
5. Validating error handling and edge cases

GAMING RESISTANCE:
==================
These tests CANNOT be gamed because:
1. Use actual Click CliRunner (not mocked CLI)
2. Verify real stdout/stderr output
3. Test interactive prompts and responses
4. Check exit codes and error messages
5. Ensure existing commands still work (no regressions)
6. Cannot fake CLI without implementing actual Click commands

# ============================================================================
# SUMMARY OF TEST COVERAGE
# ============================================================================
"""
These functional tests cover:

1. CORE FUNCTIONALITY (test_template_discovery_functional.py):
   - Project detection (Docker, languages, databases)
   - Recommendation scoring and ranking
   - End-to-end workflows
   - Edge cases and error handling

2. CLI INTEGRATION (test_template_recommendation_cli.py):
   - --recommend flag functionality
   - Rich console output formatting
   - Interactive accept/decline flow
   - Backward compatibility
   - Error handling and edge cases
   - Integration with real templates

GAMING RESISTANCE FEATURES:
- Use real file systems and file I/O
- Verify actual command execution via CliRunner
- Test logical correctness (Docker → Docker template)
- Check complete workflows end-to-end
- Validate against actual template files
- Cannot be satisfied by mocks or stubs

TEST PHILOSOPHY:
- Tests WHAT the system does (user perspective)
- Not HOW it does it (implementation details)
- Few but critical tests (high value)
- Fail honestly when functionality missing
- Guide implementation through TDD

NEXT STEPS:
1. Run these tests (they will fail - no implementation yet)
2. Implement each component to make tests pass
3. Tests serve as acceptance criteria
4. Green tests = feature is working correctly
