## 🛠️ Test Commands Reference

```bash
# Run all tests
./run-phase-tests.sh

# Run specific test file
npm test -- sessionUISlice.test.js --watchAll=false
npm test -- activeSessionSlice.test.js --watchAll=false

npm test -- --coverage --watchAll=false

# Watch mode (development)
npm test

# Verbose output
npm test -- --verbose

# Clear cache if issues
npm test -- --clearCache
```

## ✅ Testing Workflow

### Recommended Testing Order:

1. **Automated Tests First** ✅
   ```bash
   ./run-phase-tests.sh
   ```
   - If fails: Fix code, re-run
   - If passes: Proceed to manual

2. **Phase 1 Manual Tests** ✅
   - Test all 8 modals
   - Verify Redux state updates
   - Check DevTools actions

3. **Phase 2 Manual Tests** ✅
   - Test session lifecycle
   - Test connection monitoring
   - Test leave functionality

4. **Final Verification** ✅
   - No console errors
   - Redux state correct
   - Memory stable

## 🎓 Learning from Tests

### Understanding the Tests:

Each test file follows this structure:

```javascript
describe('Feature', () => {
  describe('Action Type', () => {
    it('should do something specific', () => {
      // Arrange: Set up initial state
      // Act: Dispatch action
      // Assert: Verify new state
    });
  });
});
```

### Example Test Explained:

```javascript
it('should handle openModal', () => {
  // Arrange: Start with initial state (all modals closed)
  const initialState = { modals: { settings: false } };

  // Act: Dispatch openModal action
  const actual = sessionUIReducer(initialState, openModal('settings'));

  // Assert: Verify settings modal is now open
  expect(actual.modals.settings).toBe(true);
});
```

This tests that:
1. Action is dispatched correctly
2. Reducer handles action properly
3. State updates as expected

## 🐛 Common Issues & Solutions

### Issue 1: Tests fail with "Cannot find module"

**Solution:**
```bash
cd jam-ui
npm install
npm test
```

### Issue 2: Manual tests fail - modal doesn't open

**Solution:**
1. Check Redux DevTools for action
2. If no action: Check button onClick
3. If action fires: Check reducer
4. If reducer works: Check selector usage

### Issue 3: Session doesn't join

**Solution:**
1. Check backend services running
2. Check WebSocket connection
3. Check console for errors
4. Verify guards pass first

### Issue 4: State doesn't clear on leave

**Solution:**
1. Verify clearSession action fires
2. Check Redux DevTools
3. Verify reducer returns initialState
4. Check for competing state updates

## 📈 Success Metrics

### Tests Are Successful When:

✅ All 73+ automated tests pass
✅ All 8 modals work in browser
✅ Session lifecycle completes
✅ Redux state matches expectations
✅ No console errors
✅ No memory leaks
✅ DevTools shows all actions

### Ready for Phase 3 When:

✅ All tests green
✅ Manual testing complete
✅ Documentation reviewed
✅ Code committed to git
✅ Team reviewed changes (optional)
