# Integration Test Fix Plan
|
|
|
|
## Executive Summary
|
|
|
|
We're developing a comprehensive test suite from scratch on a feature branch. Unit tests are solid (932 passing, 87.8% coverage), but integration tests need significant work (58 failures out of 246 tests).
|
|
|
|
**Key Decision**: Should we fix all integration tests before merging, or merge with a phased approach?
|
|
|
|
## Current Situation
|
|
|
|
### What's Working
|
|
- ✅ **Unit Tests**: 932 tests, 87.8% coverage, all passing
|
|
- ✅ **Test Infrastructure**: Vitest, factories, builders all set up
|
|
- ✅ **CI/CD Pipeline**: Runs in ~2 minutes (but hiding failures)
|
|
|
|
### What Needs Work
|
|
- ⚠️ **Integration Tests**: 58 failures (23.6% failure rate)
|
|
- ⚠️ **CI Configuration**: `|| true` hiding test failures
|
|
- ⚠️ **No E2E Tests**: Not started yet
|
|
|
|
## Root Cause Analysis
|
|
|
|
### 1. Database State Management (9 failures)
|
|
```
|
|
UNIQUE constraint failed: templates.workflow_id
|
|
database disk image is malformed
|
|
```
|
|
**Fix**: Isolate database instances per test
|
|
|
|
### 2. MCP Protocol Response Structure (16 failures)
|
|
```
|
|
Cannot read properties of undefined (reading 'text')
|
|
```
|
|
**Fix**: Update error-handling tests to match actual response structure
|
|
|
|
### 3. MSW Not Initialized (6 failures)
|
|
```
|
|
Request failed with status code 501
|
|
```
|
|
**Fix**: Add MSW setup to each test file
|
|
|
|
### 4. FTS5 Search Syntax (7 failures)
|
|
```
|
|
fts5: syntax error near ""
|
|
```
|
|
**Fix**: Handle empty search terms, fix NOT query syntax
|
|
|
|
### 5. Session Management Timeouts (5 failures)
|
|
**Fix**: Proper async cleanup in afterEach hooks
|
|
|
|
### 6. Performance Thresholds (15 failures)
|
|
**Fix**: Adjust thresholds to match actual performance
|
|
|
|
## Proposed Course of Action
|
|
|
|
### Option A: Fix Everything Before Merge (3-4 weeks)
|
|
|
|
**Pros:**
|
|
- Clean, fully passing test suite
|
|
- No technical debt
|
|
- Sets high quality bar
|
|
|
|
**Cons:**
|
|
- Delays value delivery
|
|
- Blocks other development
|
|
- Risk of scope creep
|
|
|
|
### Option B: Phased Approach (Recommended)
|
|
|
|
#### Phase 1: Critical Fixes (1 week)
|
|
1. **Remove `|| true` from CI** - See real status
|
|
2. **Fix Database Isolation** - Prevents data corruption
|
|
3. **Fix MSW Setup** - Unblocks API tests
|
|
4. **Update MCP error-handling tests** - Quick fix
|
|
|
|
**Target**: 30-35 tests fixed, ~85% pass rate
|
|
|
|
#### Phase 2: Merge & Iterate (Week 2)
|
|
1. **Merge to main with known issues**
|
|
- Document failing tests
|
|
- Create issues for remaining work
|
|
- Set CI to warn but not block
|
|
|
|
2. **Benefits:**
|
|
- Team gets unit test coverage immediately
|
|
- Integration tests provide partial coverage
|
|
- Incremental improvement approach
|
|
|
|
#### Phase 3: Complete Integration Tests (Week 3-4)
|
|
- Fix remaining FTS5 search issues
|
|
- Resolve session management timeouts
|
|
- Adjust performance thresholds
|
|
- Target: 100% pass rate
|
|
|
|
#### Phase 4: E2E Tests (Week 5-6)
|
|
- Build on stable integration test foundation
|
|
- Focus on critical user journeys
|
|
|
|
## Implementation Steps
|
|
|
|
### Week 1: Critical Infrastructure
|
|
|
|
```bash
|
|
# Day 1-2: Fix CI and Database
|
|
- Remove || true from workflow
|
|
- Implement TestDatabase.create() for isolation
|
|
- Fix FTS5 rebuild syntax
|
|
|
|
# Day 3-4: Fix MSW and MCP
|
|
- Add MSW to test files
|
|
- Apply response.content[0] pattern to error-handling.test.ts
|
|
|
|
# Day 5: Test & Document
|
|
- Run full suite
|
|
- Document remaining issues
|
|
- Create tracking board
|
|
```
|
|
|
|
### Week 2: Merge Strategy
|
|
|
|
```yaml
|
|
# Modified CI configuration
|
|
- name: Run integration tests
|
|
run: |
|
|
npm run test:integration || echo "::warning::Integration tests have known failures"
|
|
# Still exit 0 to allow merge, but warn
|
|
continue-on-error: true # Temporary until all fixed
|
|
```
|
|
|
|
## Success Metrics
|
|
|
|
### Week 1 Goals
|
|
- [ ] CI shows real test status
|
|
- [ ] Database tests isolated (9 fixed)
|
|
- [ ] MSW tests passing (6 fixed)
|
|
- [ ] MCP error tests fixed (16 fixed)
|
|
- [ ] ~85% integration test pass rate
|
|
|
|
### End State Goals
|
|
- [ ] 100% integration test pass rate
|
|
- [ ] No flaky tests
|
|
- [ ] E2E test suite started
|
|
- [ ] CI blocks on failures
|
|
|
|
## Risk Mitigation
|
|
|
|
### If Fixes Take Longer
|
|
- Focus on critical path tests only
|
|
- Temporarily skip problematic tests
|
|
- Adjust thresholds rather than fix performance
|
|
|
|
### If New Issues Arise
|
|
- Time-box investigation (2 hours max)
|
|
- Document and move on
|
|
- Create follow-up tickets
|
|
|
|
## Team Communication
|
|
|
|
### Messaging
|
|
```
|
|
We're adding comprehensive test coverage to ensure code quality.
|
|
Unit tests are complete and passing (932 tests, 87.8% coverage).
|
|
Integration tests need some work - we'll fix critical issues this week
|
|
and merge with a plan to complete the remaining fixes.
|
|
```
|
|
|
|
### Benefits to Emphasize
|
|
- Catching bugs before production
|
|
- Faster development with safety net
|
|
- Better code documentation through tests
|
|
- Reduced manual testing burden
|
|
|
|
## Decision Point
|
|
|
|
**Recommendation**: Go with Option B (Phased Approach)
|
|
|
|
**Rationale:**
|
|
1. Delivers immediate value (unit tests)
|
|
2. Makes progress visible
|
|
3. Allows parallel development
|
|
4. Reduces merge conflicts
|
|
5. Pragmatic over perfect
|
|
|
|
**Next Step**: Get team consensus on phased approach, then start Week 1 fixes. |
