# QA: Test Output Style Enforcement Mechanism

## Description
## Testing Scope

Test the output style enforcement mechanism implemented in claude-mpm to ensure it properly enforces the "claude-mpm" output style.

## Key Files to Test
1. `src/claude_mpm/core/output_style_manager.py` - Contains enforcement logic
2. `src/claude_mpm/core/interactive_session.py` - Contains startup enforcement  
3. `src/claude_mpm/core/framework_loader.py` - Contains initialization

## Test Requirements

### 1. Basic Enforcement Test
- Read current Claude settings.json file
- Temporarily change activeOutputStyle to "default" 
- Run enforcement check via output_style_manager
- Verify it automatically changes back to "claude-mpm"
- Test logging and error handling

### 2. Startup Integration Test
- Simulate claude-mpm startup process
- Verify output style is automatically set to "claude-mpm" during initialization
- Check that appropriate logging messages are generated
- Verify integration with interactive_session and framework_loader

### 3. Edge Cases and Error Handling
- Test with missing ~/.claude/settings.json file
- Test with corrupted/invalid JSON in settings.json
- Test with settings.json that lacks activeOutputStyle field
- Test with read-only settings.json file (permission issues)
- Test behavior with older Claude Code versions

### 4. Comprehensive System Test
- Test full end-to-end flow from claude-mpm startup to enforcement
- Verify enforcement doesn't interfere with normal operations
- Test that enforcement is idempotent (running multiple times is safe)
- Validate performance impact is minimal

## Deliverables

Create test scripts that:
1. Execute all test scenarios systematically
2. Provide clear pass/fail results for each test case
3. Generate detailed logs of enforcement behavior
4. Report any issues or failures discovered
5. Verify the enforcement mechanism works reliably

## Success Criteria

- All basic enforcement tests pass
- Startup integration works correctly
- Edge cases are handled gracefully
- No performance degradation
- Clean test execution with clear reporting
