Phase 4: Testing and Refinement of Conflict Resolver Agent
## Overview
Comprehensive testing of the Conflict Resolver agent's **autonomous resolution capabilities** - verifying it can actually resolve conflicts by editing files, committing, and pushing.
## Key Testing Focus
⚠️ **Test AUTONOMOUS EXECUTION, not just suggestions:**
- Agent edits files correctly
- Agent removes conflict markers
- Agent creates valid commits
- Agent pushes successfully
- Resolved MRs are actually mergeable
## Tasks
### Test Scenario Creation
- [ ] Create test MRs with simple conflicts (both modified same lines)
- [ ] Create test MRs with multi-file conflicts
- [ ] Create test MRs with complex logic conflicts
- [ ] Create test MRs with renamed file conflicts
- [ ] Create test MRs with binary file conflicts (should error gracefully)
### Autonomous Execution Testing
#### File Editing
- [ ] Verify agent calls `edit_file` with correct parameters
- [ ] Verify conflict markers are completely removed
- [ ] Verify resolution is applied correctly
- [ ] Verify no syntax errors introduced
- [ ] Verify file encoding preserved
#### Git Operations
- [ ] Verify agent stages all resolved files
- [ ] Verify commit message is descriptive
- [ ] Verify commit includes all changes
- [ ] Verify commit author is set correctly
- [ ] Verify push succeeds to source branch
#### End-to-End Flow
- [ ] User approves resolution plan
- [ ] Agent edits files autonomously
- [ ] Agent commits changes
- [ ] Agent pushes to branch
- [ ] MR becomes mergeable
- [ ] Agent reports success with commit SHA
### Approval Workflow Testing
- [ ] Agent requests approval before executing
- [ ] Agent shows clear plan of what will change
- [ ] User can approve or decline
- [ ] User can ask questions before approving
- [ ] Agent only executes after explicit approval
- [ ] Agent handles "no" gracefully (provides alternatives)
### Error Handling Testing
#### File Operation Errors
- [ ] Test: File is read-only (permission error)
- [ ] Test: File is locked by another process
- [ ] Test: Invalid file path
- [ ] Test: File encoding issues
#### Git Operation Errors
- [ ] Test: Push fails (network issue)
- [ ] Test: Branch is protected
- [ ] Test: Conflicts remain after resolution attempt
- [ ] Test: Working directory not clean
- [ ] Test: Authentication fails
#### Recovery Testing
- [ ] Agent reports errors clearly
- [ ] Agent suggests next steps
- [ ] Agent can retry after fixing issue
- [ ] User can manually complete if agent fails
### Safety Testing
#### Branch Protection
- [ ] Agent respects protected branch rules
- [ ] Agent cannot force push
- [ ] Agent respects push rules
- [ ] Agent respects required approvals
#### Rollback Capability
- [ ] Agent can revert its commit if user requests
- [ ] Agent provides clear rollback instructions
- [ ] Rollback doesn't break MR state
#### Audit Trail
- [ ] All agent file edits are logged
- [ ] All git operations are logged
- [ ] User approvals are logged
- [ ] Errors are logged with context
### Conflict Resolution Quality
#### Resolution Accuracy
- [ ] Simple conflicts resolved correctly
- [ ] Multi-file conflicts resolved consistently
- [ ] Logic preserved after resolution
- [ ] No unintended side effects
#### Code Quality
- [ ] No syntax errors introduced
- [ ] Formatting preserved
- [ ] Imports/dependencies intact
- [ ] Tests still pass after resolution
### Performance Testing
- [ ] Measure file edit operation time
- [ ] Measure commit creation time
- [ ] Measure push operation time
- [ ] Test with large files (1000+ lines)
- [ ] Test with many files (20+ conflicts)
### Integration Testing
#### Full Workflow
- [ ] User clicks "Resolve with AI"
- [ ] Chat opens with agent
- [ ] Agent analyzes conflicts
- [ ] Agent presents plan
- [ ] User approves
- [ ] Agent executes (edit, commit, push)
- [ ] MR shows new commit
- [ ] MR is mergeable
- [ ] User can review commit
#### CI/CD Integration
- [ ] Pipeline triggers after agent push
- [ ] Tests run on agent's commit
- [ ] Agent reports CI status
- [ ] Agent suggests fixes if CI fails
### Edge Cases
#### Complex Scenarios
- [ ] Merge conflicts + failing tests
- [ ] Conflicts in multiple branches
- [ ] Conflicts with stale branches
- [ ] Very old conflicts (100+ commits behind)
#### Boundary Conditions
- [ ] Empty file conflicts
- [ ] Single line conflicts
- [ ] Entire file conflicts
- [ ] Whitespace-only conflicts
## Acceptance Criteria
- [ ] Agent **successfully resolves** conflicts autonomously in >70% of test cases
- [ ] All file edits are correct and complete
- [ ] All commits are valid and pushable
- [ ] All pushes succeed (when permissions allow)
- [ ] Resolved MRs are actually mergeable
- [ ] No security vulnerabilities introduced
- [ ] Performance meets targets (<30s total for simple conflicts)
- [ ] Error handling is graceful for all failure modes
- [ ] Approval workflow works correctly
- [ ] Safety mechanisms prevent destructive actions
## Success Criteria
**Must achieve:**
- ✅ 70%+ autonomous resolution success rate
- ✅ <5% resolutions need correction
- ✅ 0 force pushes or destructive actions
- ✅ 100% approval requests before execution
- ✅ Clear error messages for all failures
## Test Results Documentation
- [ ] Document success rate by conflict type
- [ ] Document common failure modes
- [ ] Document average execution time
- [ ] Document user feedback on autonomous behavior
- [ ] Document safety mechanism effectiveness
## Prompt Refinement Based on Testing
- [ ] Adjust confidence thresholds
- [ ] Improve resolution strategies
- [ ] Enhance error recovery
- [ ] Optimize approval request clarity
- [ ] Improve commit message generation
## Files Changed
- Agent configuration in AI Catalog (system prompt updates)
- Test fixtures/data as needed
- Test scripts for automation
## Timeline
**3-4 days** (additional time for autonomous execution testing)
