# Plan: Add Comprehensive Magnitude Tests for All Features

**Priority:** CRITICAL - Must be done second (after Playwright scaffolding)
**Dependencies:** 01-playwright-scaffolding.md
**Affects:** Code quality, regression prevention, production confidence

## Overview

Create comprehensive Magnitude test coverage for ALL existing and new features. Every user flow must be tested fully, including both happy paths and unhappy paths.

## Current State

- No Magnitude tests exist
- No test coverage for critical flows (auth, chat, node creation, galaxy)
- No regression testing
- Production deployments lack confidence

## Test Coverage Required

### 1. Authentication Flow Tests

#### `tests/magnitude/auth.mag.ts`

**Happy Paths:**
- User can log in with valid Bluesky credentials
- User can log out successfully
- User session persists across page refreshes
- User can access protected routes after authentication

**Unhappy Paths:**
- Login fails with invalid credentials
- Login fails with non-existent handle
- Unauthenticated user redirected from protected routes
- Session expiry handled gracefully

```typescript
import { test } from 'magnitude-test';

test('User can log in with valid credentials', async (agent) => {
  await agent.open('http://localhost:3000');
  await agent.check('Login page is visible');

  await agent.act('Click "Log in with Bluesky" button')
    .data({
      handle: process.env.TEST_USER_HANDLE,
      password: process.env.TEST_USER_PASSWORD
    });

  await agent.check('User is redirected to Bluesky OAuth');
  await agent.check('User is redirected back to Ponderants');
  await agent.check('User sees authenticated interface');
  await agent.check('Profile menu is visible');
});

test('Login fails with invalid credentials', async (agent) => {
  await agent.open('http://localhost:3000');
  await agent.act('Click "Log in with Bluesky" button')
    .data({
      handle: 'invalid-user.bsky.social',
      password: 'wrongpassword'
    });

  await agent.check('Error message is displayed');
  await agent.check('User remains on login page');
});

test('User session persists across refresh', async (agent) => {
  // First login
  await agent.open('http://localhost:3000');
  await agent.act('Log in with valid credentials');
  await agent.check('User is authenticated');

  // Refresh page
  await agent.act('Refresh the page');
  await agent.check('User is still authenticated');
  await agent.check('Profile menu is still visible');
});

test('User can log out', async (agent) => {
  await agent.open('http://localhost:3000');
  await agent.act('Log in with valid credentials');
  await agent.check('User is authenticated');

  await agent.act('Click profile menu');
  await agent.act('Click "Log out" button');
  await agent.check('User is redirected to login page');
  await agent.check('Session is cleared');
});
```

### 2. Chat Interface Tests

#### `tests/magnitude/chat.mag.ts`

**Happy Paths:**
- User can send text message and receive AI response
- User can use voice input and receive AI response
- User can see typing indicator while AI is thinking
- User can create a node from conversation
- User can select AI persona
- Chat history persists

**Unhappy Paths:**
- Empty message submission is prevented
- Voice input fails gracefully without microphone permission
- AI error displays user-friendly message
- Network error handled with retry option

```typescript
import { test } from 'magnitude-test';

test('User can send message and receive AI response', async (agent) => {
  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  await agent.act('Type "What is the meaning of life?" into chat input');
  await agent.act('Press Enter to send');

  await agent.check('Message appears in chat history');
  await agent.check('Typing indicator is visible');
  await agent.check('AI response appears after typing indicator disappears');
  await agent.check('Response contains thoughtful content');
});

test('User can use voice input', async (agent) => {
  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  await agent.act('Click microphone button');
  await agent.check('Recording indicator is visible');

  await agent.act('Speak "Hello, how are you?"');
  await agent.act('Click microphone button to stop recording');

  await agent.check('Transcribed text appears in chat');

  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  await agent.act('Press Enter without typing anything');
  await agent.check('No message is sent');
  await agent.check('Send button remains disabled');
});

test('AI error displays user-friendly message', async (agent) => {
  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  // Simulate network error by blocking API calls
  await agent.act('Send a message while API is blocked');

  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  const emojiContent = '🎉 '.repeat(100) + 'Hello world! 👋 ';

  await agent.act('Create new node');
  await agent.act('Type "Emoji Test" into title');
  await agent.act('Type emoji content into body').data({ body: emojiContent });
  await agent.act('Click "Publish" button');

  await agent.check('Node is published without exceeding 300 grapheme limit');
  await agent.check('Emojis are counted as 1 grapheme each');
});

test('Node creation fails without title', async (agent) => {
  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  await agent.act('Create new node');
  await agent.act('Type "Some body content" into body field');

  await agent.check('Node is not published');
});

test('Node links to existing nodes', async (agent) => {
  await agent.open('http://localhost:3000/chat');
  await agent.act('Log in if needed');

  // Create first node
  await agent.act('Create node titled "Philosophy Basics"');
  await agent.check('First node is published');

  // Create second node that links to first
  await agent.act('Create new node titled "Advanced Philosophy"');
  await agent.check('AI suggests linking to "Philosophy Basics"');
  await agent.act('Accept suggested link');
  await agent.act('Publish node');

  await agent.check('Node is published with link');
  await agent.check('Graph relationship exists in database');
});
```

```

## Implementation Steps

1. **Create test directory structure**
   ```bash
   mkdir -p tests/magnitude
   ```

2. **Create test files in order**
   - `tests/magnitude/auth.mag.ts` - Authentication tests
   - `tests/magnitude/chat.mag.ts` - Chat interface tests
   - `tests/magnitude/nodes.mag.ts` - Node creation tests
   - `tests/magnitude/galaxy.mag.ts` - Galaxy visualization tests
   - `tests/magnitude/voice.mag.ts` - Voice feature tests
   - `tests/magnitude/integration.mag.ts` - Full user journeys

3. **Update package.json**
   ```json
   {
     "scripts": {
       "test": "npx magnitude",
       "test:watch": "npx magnitude --watch"
     }
   }
   ```

4. **Create test data helpers**
   ```typescript
   // tests/magnitude/helpers/data.ts
   export const createTestNode = (index: number) => ({
     title: `Test Node ${index}`,
     body: `This is test content for node ${index}. It discusses various topics.`
   });
   ```

5. **Run tests and fix issues**
   - Run each test file individually first
   - Fix failing tests
   - Run full suite
   - Ensure all tests pass

## Success Criteria

- ✅ All authentication flows tested (happy + unhappy paths)
- ✅ All chat interactions tested (text, voice, AI response)
- ✅ All node creation scenarios tested (simple, thread, emojis, links)
- ✅ All galaxy visualization features tested (load, click, navigate)
- ✅ All voice features tested (record, transcribe, TTS)
- ✅ Integration tests cover complete user journeys
- ✅ All tests pass reliably
- ✅ Test suite runs in CI/CD
- ✅ New features cannot be merged without tests
