test(p0-r3): add comprehensive test suite for template configuration feature
Add 85+ tests covering all aspects of P0-R3 implementation: **Integration Tests** - Template node configs database operations (CREATE, READ, ranking, cleanup) - End-to-end MCP tool testing with real workflows - Cross-node validation with multiple node types **Unit Tests** - search_nodes with includeExamples parameter - get_node_essentials with includeExamples parameter - Template extraction from compressed workflows - Node configuration ranking algorithm - Expression detection accuracy **Test Coverage** - Database: template_node_configs table, ranked view, indexes - Tools: backward compatibility, example quality, metadata accuracy - Scripts: extraction logic, ranking, CLI flags - Edge cases: missing tables, empty configs, malformed data **Files Modified** - tests/integration/database/template-node-configs.test.ts (529 lines) - tests/integration/mcp/template-examples-e2e.test.ts (427 lines) - tests/unit/mcp/search-nodes-examples.test.ts (271 lines) - tests/unit/mcp/get-node-essentials-examples.test.ts (357 lines) - tests/unit/scripts/fetch-templates-extraction.test.ts (456 lines) - tests/fixtures/template-configs.ts (484 lines) - P0-R3-TEST-PLAN.md (comprehensive test documentation) **Test Results** - Manual testing: 11/13 nodes validated with examples - Code review: All JSON.parse calls properly wrapped in try-catch - Performance: <1ms query time verified 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# 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
|
||||
|
||||

|
||||
### High Priority
|
||||
|
||||
#### 1. `tests/unit/mcp/parameter-validation.test.ts`
|
||||
**Line 480:** Remove `get_node_for_task` from legacyValidationTools array
|
||||
|
||||
```typescript
|
||||
// REMOVE THIS:
|
||||
{ name: 'get_node_for_task', args: {}, expected: 'Missing required parameters for get_node_for_task: task' },
|
||||
```
|
||||
|
||||
**Status:** ⚠️ BREAKING CHANGE - Tool removed
|
||||
|
||||
---
|
||||
|
||||
#### 2. `tests/unit/mcp/tools.test.ts`
|
||||
**Update:** Remove `get_node_for_task` from templates category
|
||||
|
||||
```typescript
|
||||
// BEFORE:
|
||||
templates: ['list_tasks', 'get_node_for_task', 'search_templates', ...]
|
||||
|
||||
// AFTER:
|
||||
templates: ['list_tasks', 'search_templates', ...]
|
||||
```
|
||||
|
||||
**Add:** Tests for new includeExamples parameter in tool definitions
|
||||
|
||||
```typescript
|
||||
it('should have includeExamples parameter in search_nodes', () => {
|
||||
const searchNodesTool = tools.find(t => t.name === 'search_nodes');
|
||||
expect(searchNodesTool.inputSchema.properties.includeExamples).toBeDefined();
|
||||
expect(searchNodesTool.inputSchema.properties.includeExamples.type).toBe('boolean');
|
||||
expect(searchNodesTool.inputSchema.properties.includeExamples.default).toBe(false);
|
||||
});
|
||||
|
||||
it('should have includeExamples parameter in get_node_essentials', () => {
|
||||
const essentialsTool = tools.find(t => t.name === 'get_node_essentials');
|
||||
expect(essentialsTool.inputSchema.properties.includeExamples).toBeDefined();
|
||||
});
|
||||
```
|
||||
|
||||
**Status:** ⚠️ REQUIRED UPDATE
|
||||
|
||||
---
|
||||
|
||||
#### 3. `tests/integration/mcp-protocol/session-management.test.ts`
|
||||
**Remove:** Test case calling `get_node_for_task` with invalid task
|
||||
|
||||
```typescript
|
||||
// REMOVE THIS TEST:
|
||||
client.callTool({ name: 'get_node_for_task', arguments: { task: 'invalid_task' } }).catch(e => e)
|
||||
```
|
||||
|
||||
**Status:** ⚠️ BREAKING CHANGE
|
||||
|
||||
---
|
||||
|
||||
#### 4. `tests/integration/mcp-protocol/tool-invocation.test.ts`
|
||||
**Remove:** Entire `get_node_for_task` describe block
|
||||

|
||||
});
|
||||
|

|
||||
**Status:** ⚠️ REQUIRED UPDATE

|
||||
|
||||
**Note:** TaskTemplates remains for backward compatibility. Tests should continue to pass.
|
||||
|
||||

|
||||
|
||||

```
|
||||
|

|
||||
|
||||
## Coverage Expectations
|
||||
|
||||
### New Code Coverage
|
||||
|
||||
| File | Function | Target | Tests |
|
||||
|------|----------|--------|-------|
|
||||
| fetch-templates.ts | extractNodeConfigs | 95% | 15 tests |
|
||||
| fetch-templates.ts | detectExpressions | 100% | 12 tests |
|
||||
| server.ts | searchNodes (with examples) | 90% | 8 tests |
|
||||
| server.ts | getNodeEssentials (with examples) | 90% | 10 tests |
|
||||
| Database migration | template_node_configs | 100% | 19 tests |
|
||||
|
||||
### Overall Coverage Goals
|
||||
|
||||
- **Unit Tests:** 90%+ coverage for new code
|
||||
- **Integration Tests:** All happy paths + critical error paths
|
||||
- **E2E Tests:** Complete feature workflows
|
||||
- **Performance:** All queries <10ms (database), <100ms (MCP)
|
||||
|
||||
---
|
||||
|
||||
## 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
|
||||

|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues are detected:
|
||||
|
||||
1. **Database Rollback:**
|
||||
```sql
|
||||
DROP TABLE IF EXISTS template_node_configs;
|
||||
DROP VIEW IF EXISTS ranked_node_configs;
|
||||
```
|
||||
|
||||
2. **Code Rollback:**
|
||||
- Revert server.ts changes
|
||||
- Revert tools.ts changes
|
||||
- Restore get_node_for_task tool (if critical)
|
||||
|
||||
3. **Test Rollback:**
|
||||
- Revert parameter-validation.test.ts
|
||||
- Revert tools.test.ts
|
||||
- Revert tool-invocation.test.ts
