# P0-R3 Feature Test Coverage Plan
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines comprehensive test coverage for the P0-R3 feature (Template-based Configuration Examples). The feature adds real-world configuration examples from popular templates to node search and essentials tools.
|
||||
|
||||
**Feature Overview:**
|
||||
- New database table: `template_node_configs` (197 pre-extracted configurations)
|
||||
- Enhanced tools: `search_nodes({includeExamples: true})` and `get_node_essentials({includeExamples: true})`
|
||||
- Breaking changes: Removed `get_node_for_task` tool
|
||||
|
||||

||||
|
||||
---
|
||||
|
||||
## Test Infrastructure
|
||||
|
||||
### Dependencies Required
|
||||
All dependencies already present in `package.json`:
|
||||
- vitest (test runner)
|
||||
- better-sqlite3 (database)
|
||||
- @vitest/coverage-v8 (coverage)
|
||||
|
||||
### Test Utilities Used
|
||||
- TestDatabase helper (from existing test utils)
|
||||
- createTestDatabaseAdapter (from existing test utils)
|
||||
- Standard vitest matchers
|
||||
|
||||
### No New Dependencies Required ✅
|
||||
|
||||
---
|
||||
|
||||
## Regression Prevention
|
||||
|
||||
### Critical Paths Protected
|
||||
|
||||
1. **Backward Compatibility**
|
||||
- Tools work without includeExamples parameter
|
||||
- Existing workflows unchanged
|
||||
- Cache keys differentiated
|
||||
|
||||
2. **Performance**
|
||||
- No degradation when includeExamples=false
|
||||
- Indexed queries <10ms
|
||||
- Example fetch errors don't break responses
|
||||
|
||||
3. **Data Integrity**
|
||||
- Foreign key constraints enforced
|
||||
- JSON validation in all fields
|
||||
- Rank calculations correct
|
||||
|
||||
---
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
### GitHub Actions Updates
|
||||
No changes required. Existing test commands will run new tests:
|
||||
|
||||
```yaml
|
||||
- run: npm test
|
||||
- run: npm run test:coverage
|
||||
```
|
||||
|
||||
### Coverage Thresholds
|
||||
Current thresholds maintained. Expected improvements:
|
||||
- Lines: +2%
|
||||
- Functions: +3%
|
||||
- Branches: +2%
|
||||
|
||||

|
||||
|
||||
## Manual Testing Checklist
|
||||
|
||||
### Pre-Deployment Verification
|
||||
|
||||
- [ ] Run `npm run rebuild` - Verify migration applies cleanly
|
||||
- [ ] Run `npm run fetch:templates --extract-only` - Verify extraction works
|
||||
- [ ] Check database: `SELECT COUNT(*) FROM template_node_configs` - Should be ~197
|
||||
- [ ] Test MCP tool: `search_nodes({query: "webhook", includeExamples: true})`
|
||||
- [ ] Test MCP tool: `get_node_essentials({nodeType: "nodes-base.webhook", includeExamples: true})`
|
||||
- [ ] Verify backward compatibility: Tools work without includeExamples parameter
|
||||
- [ ] Performance test: Query 100 nodes with examples < 200ms
|
||||

||||
```
|
||||
|
||||
2. **Code Rollback:**
|
||||
- Revert server.ts changes
|
||||
- Revert tools.ts changes
|
||||
- Restore get_node_for_task tool (if critical)
|
||||
|
||||
3. **Test Rollback:**
