- Fixed test-helpers.ts to correctly wrap executeTool responses in MCP format
- Updated all tests to expect correct response structures:
- list_nodes returns {nodes: [...], totalCount}
- search_nodes returns {query, results: [...], totalCount, mode?}
- list_ai_tools returns {tools: [...]}
- list_tasks returns {totalTasks, categories: {...}} or {category, tasks: [...]}
- Fixed property expectations (nodeType instead of name, etc.)
- Reduced failing tests from 67 to 7

## Monitoring & Maintenance
|
||
|
||
### Daily
|
||

|
||
- [ ] Review failed tests
|
||
- [ ] Monitor flaky tests
|
||
|
||
### Weekly
|
||
- [ ] Review coverage reports
|
||
- [ ] Update test documentation
|
||
- [ ] Performance benchmark review
|
||
- [ ] Team sync on testing progress
|
||
|
||
### Monthly
|
||

|
||
- [ ] Review and refactor tests
|
||
- [ ] Update testing strategy
|
||
- [ ] Training/knowledge sharing
|
||
|
||
## Risk Mitigation
|
||
|
||
### Technical Risks
|
||
- [ ] Mock complexity - Use simple, maintainable mocks
|
||
- [ ] Test brittleness - Focus on behavior, not implementation
|
||
- [ ] Performance impact - Run heavy tests in parallel
|
||
- [ ] Flaky tests - Proper async handling and isolation
|
||
|
||
### Process Risks
|
||
- [ ] Slow adoption - Provide training and examples
|
||
- [ ] Coverage gaming - Review test quality, not just numbers
|
||
- [ ] Maintenance burden - Automate what's possible
|
||
- [ ] Integration complexity - Use test containers
|
||
|
