# Phase 17: Unit Tests (Jest) Verification Report

**Phase Goal:** Create Jest unit tests for JKSessionSettingsModal component covering critical paths
**Verified:** 2026-02-08T14:30:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Test file exists and runs without errors | ✓ VERIFIED | Test file exists at correct path, 149 lines, runs successfully |
| 2 | UNIT-01: Test verifies modal renders with currentSession props (privacy, description displayed) | ✓ VERIFIED | 3 tests in "rendering with currentSession props (UNIT-01)" describe block - all passing |
| 3 | UNIT-02: Test verifies save button calls onSave with correctly transformed payload | ✓ VERIFIED | 2 tests in "save functionality (UNIT-02)" describe block - both passing |
| 4 | UNIT-03: Test verifies loading state disables form interactions | ✓ VERIFIED | 4 tests in "loading state (UNIT-03)" describe block - all passing |
| 5 | All tests pass with npm run test:unit | ✓ VERIFIED | Test suite passes: 9 tests, 0 failures (verified with npm run test:unit -- --testPathPattern=JKSessionSettingsModal) |

**Score:** 5/5 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js` | Jest unit tests for JKSessionSettingsModal component | ✓ VERIFIED | EXISTS (149 lines), SUBSTANTIVE (9 tests, 10 expect statements, 4 describe blocks, no stubs/TODOs), WIRED (imported from ../JKSessionSettingsModal, uses SESSION_PRIVACY_MAP from globals.js) |

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| JKSessionSettingsModal.test.js | JKSessionSettingsModal.js | import | ✓ WIRED | Line 3: `import JKSessionSettingsModal from '../JKSessionSettingsModal'` - component exists at correct path, 102 lines |
| JKSessionSettingsModal.test.js | globals.js | import SESSION_PRIVACY_MAP | ✓ WIRED | Line 4: `import { SESSION_PRIVACY_MAP } from '../../../helpers/globals.js'` - constant used 10 times in tests, exists in globals.js at line 419 |
| JKSessionSettingsModal.js | JKSessionScreen.js | Component usage | ✓ WIRED | Component imported and rendered in JKSessionScreen.js (line 70, 1529-1531) - confirms real integration |

### Requirements Coverage

| Requirement | Status | Evidence |
|-------------|--------|----------|
| UNIT-01: Modal renders correctly with currentSession props (privacy, description) | ✓ SATISFIED | 3 passing tests verify privacy value display, description value display, and modal title rendering |
| UNIT-02: Save button calls onSave with correct payload (privacy number, description) | ✓ SATISFIED | 2 passing tests verify onSave called with initial values and with updated values after user changes |
| UNIT-03: Loading state disables form interactions (save button, inputs) | ✓ SATISFIED | 4 passing tests verify save button disabled, cancel button disabled, textarea disabled, and button text changes to "Saving..." |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| _None_ | - | - | - | No anti-patterns detected |

**Anti-pattern scan results:**
- No TODO/FIXME/placeholder comments
- No empty return statements
- No console.log-only implementations
- No stub patterns detected
- Test file is substantive with real assertions and interactions

### Test Execution Results

```
Test Suites: 1 passed, 1 total
Tests:       9 passed, 9 total
Snapshots:   0 total
Time:        1.179s
```

**Test breakdown:**
- **UNIT-01** (rendering with currentSession props): 3 tests
  - displays privacy value from currentSession ✓
  - displays description value from currentSession ✓
  - renders modal title ✓
- **UNIT-02** (save functionality): 2 tests
  - calls onSave with privacy and description when save clicked ✓
  - calls onSave with updated values after user changes ✓
- **UNIT-03** (loading state): 4 tests
  - disables save button when loading ✓
  - disables cancel button when loading ✓
  - disables description textarea when loading ✓
  - shows "Saving..." text on save button when loading ✓

### Test Quality Assessment

**Strengths:**
1. **Proper setup:** renderModal helper with defaultProps pattern reduces duplication
2. **Mock isolation:** react-i18next properly mocked to avoid external dependencies
3. **Real interactions:** Uses fireEvent to simulate actual user behavior (click, change)
4. **Explicit assertions:** Tests verify specific values, not just existence
5. **Requirement traceability:** Describe blocks labeled with UNIT-XX for clear mapping
6. **Component wiring verified:** Component actually used in JKSessionScreen.js

**Test coverage:**
- Component rendering: ✓ (privacy, description, title)
- State management: ✓ (initial values, updates after changes)
- Event handling: ✓ (save button click, form changes)
- Loading state: ✓ (disabled states, button text)
- Integration: ✓ (real component imported and used in app)

## Verification Details

### Level 1: Existence ✓

```bash
$ ls -la jam-ui/src/components/client/__tests__/JKSessionSettingsModal.test.js
-rw-r--r--  1 nuwan  staff  4803 Feb  8 12:20 JKSessionSettingsModal.test.js
```

**Result:** File exists (4803 bytes, 149 lines)

### Level 2: Substantive ✓

**Line count:** 149 lines (minimum 80 required) ✓
**Expected content:** Contains `describe('JKSessionSettingsModal'` ✓
**Stub patterns:** 0 TODO/FIXME/placeholder comments ✓
**Test structure:**
- 4 describe blocks ✓
- 9 test cases ✓
- 10 expect statements ✓
- Real interactions with fireEvent ✓

**Result:** Test file is SUBSTANTIVE - not a stub

### Level 3: Wired ✓

**Import verification:**
```javascript
Line 3: import JKSessionSettingsModal from '../JKSessionSettingsModal';
Line 4: import { SESSION_PRIVACY_MAP } from '../../../helpers/globals.js';
```

**Component exists:** jam-ui/src/components/client/JKSessionSettingsModal.js (102 lines) ✓
**Constant exists:** SESSION_PRIVACY_MAP in jam-ui/src/helpers/globals.js (line 419) ✓
**Component used in app:** JKSessionScreen.js imports and renders JKSessionSettingsModal ✓

**Result:** Test file is WIRED - imports real artifacts that are integrated into app

### Test Execution Verification ✓

**Command:**
```bash
cd jam-ui && npm run test:unit -- --testPathPattern=JKSessionSettingsModal
```

**Result:** 9 tests passed, 0 failures ✓
