# Task: [RELS.4001]: Integration Testing and Coverage Verification
## Status
- [x] **Task completed** - acceptance criteria met
- [x] **Tests pass** - tests executed and passing (or N/A if no tests)
- [x] **Verified** - by the verify-task agent
**Note on "Tests pass"**:
- If tests were created/modified, you MUST run them and show output
- "Tests pass" means tests were EXECUTED and all passed
- "Tests pass - N/A" is only valid for documentation-only tickets
- Test file existence alone does NOT satisfy this requirement
## Agents
- verify-task
- unit-test-runner
- commit-task
## Summary
Run comprehensive integration tests to verify all relationship tools are properly registered, execute correctly, and meet coverage thresholds defined in jest.config.js.
## Background
This is the final verification phase that confirms all four relationship tools are integrated correctly, the test suite passes, coverage meets thresholds, and all quality gates are satisfied.
This implements Phase 4 from plan.md: Integration and Verification.
## Acceptance Criteria
- [x] `npm test` passes all tests with no failures
- [x] Test coverage meets jest.config.js thresholds: >= 40% lines/functions/statements, >= 20% branches
- [x] All four relationship tools registered in toolRegistry
- [x] Integration tests confirm tools are callable through MCP interface
- [x] Tool descriptions verified for clarity and safety warnings
- [x] No TypeScript compilation errors (`npm run build`)
- [x] No linting errors (`npm run lint`)
## Technical Requirements
- Run full test suite: `npm test`
- Run with coverage: `npm test -- --coverage`
- Verify coverage thresholds (from jest.config.js):
- Lines: 40%
- Functions: 40%
- Statements: 40%
- Branches: 20%
- Check tool registration via toolRegistry.getAllTools()
- Verify each tool can be retrieved by name
- Confirm tool descriptions contain required elements
## Implementation Notes
From quality-strategy.md, integration tests should verify:
```typescript
// All tools appear in registry
const allTools = toolRegistry.getAllTools();
expect(allTools).toContainEqual(expect.objectContaining({ name: 'get_relationships' }));
expect(allTools).toContainEqual(expect.objectContaining({ name: 'create_relationship' }));
expect(allTools).toContainEqual(expect.objectContaining({ name: 'update_relationship' }));
expect(allTools).toContainEqual(expect.objectContaining({ name: 'delete_relationship' }));
// Tools can be retrieved by name
const getTool = toolRegistry.getTool('get_relationships');
expect(getTool).toBeDefined();
expect(getTool.name).toBe('get_relationships');
// Execute returns proper ApiResponse structure
const result = await getTool.execute({ table_id: 'test' });
expect(result).toHaveProperty('success');
```
Verify delete tool description contains (from plan.md):
- "WARNING: DESTRUCTIVE OPERATION"
- Mentions lookup/summary field deletion
- States data is permanent
- Recommends get_relationships first
- Recommends user confirmation
## Dependencies
- RELS.1001 - Domain setup
- RELS.1002 - GetRelationshipsTool
- RELS.1003 - Tool registration
- RELS.2001 - CreateRelationshipTool
- RELS.2002 - UpdateRelationshipTool
- RELS.3001 - DeleteRelationshipTool
All implementation tasks must be complete before integration testing.
## Risk Assessment
- **Risk**: Coverage falls below threshold
- **Mitigation**: Review uncovered code; add targeted tests for critical paths
- **Risk**: Tool not appearing in registry
- **Mitigation**: Check registration function was called; verify exports
- **Risk**: Integration test failures
- **Mitigation**: Debug specific tool; check mocking setup
## Files/Packages Affected
- src/__tests__/tools/relationships.test.ts (integration test section)
- All relationship tool files (verification only)
- src/tools/index.ts (verification only)
- src/tools/relationships/index.ts (verification only)
## Deliverables Produced
Documents created in `deliverables/` directory:
- None
## Verification Notes
Verify-task agent should run and confirm:
1. **Test Execution**:
```bash
npm test
# All tests should pass
```
2. **Coverage Report**:
```bash
npm test -- --coverage
# Verify coverage meets thresholds:
# - Lines: >= 40%
# - Functions: >= 40%
# - Statements: >= 40%
# - Branches: >= 20%
```
3. **Build Verification**:
```bash
npm run build
# Should complete without TypeScript errors
```
4. **Linting Verification**:
```bash
npm run lint
# Should show no errors
```
5. **Tool Registration**:
- Verify all 4 tools in toolRegistry.getAllTools()
- Verify each tool can be retrieved by name
- Verify tool descriptions are non-empty
6. **Safety Verification** (CRITICAL):
- DeleteRelationshipTool description contains all required warnings
- See RELS.3001 verification notes for complete checklist
Quality gates from quality-strategy.md:
- [x] All unit tests pass
- [x] Coverage thresholds met (40% lines/functions/statements, 20% branches)
- [x] No linting errors
- [x] No TypeScript errors
- [x] All four tools registered
- [x] Delete tool description contains safety warnings
- [x] All critical paths tested (see quality-strategy.md sections)
