# Plan: Add Playwright Scaffolding Files

**Priority:** CRITICAL - Must be done first
**Dependencies:** None
**Affects:** All future testing work

## Overview

Create base Playwright scaffolding files to improve efficiency of both manual Playwright MCP testing and Magnitude test automation. This infrastructure will make it easier to write, run, and maintain browser-based tests.

## Current State

- No Playwright configuration file exists
- No test helpers or utilities for common operations
- No fixtures for authenticated states
- Manual testing with Playwright MCP is inefficient
- Magnitude tests will lack reusable components

## Proposed Solution

Create a complete Playwright testing infrastructure with:

### 1. Core Configuration Files

#### `playwright.config.ts`
```typescript
import { defineConfig, devices } from '@playwright/test';

export default defineConfig({
  testDir: './tests/playwright',
  fullyParallel: true,
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  workers: process.env.CI ? 1 : undefined,
  reporter: 'html',

  use: {
    baseURL: process.env.PLAYWRIGHT_BASE_URL || 'http://localhost:3000',
    trace: 'on-first-retry',
    screenshot: 'only-on-failure',
  },

  projects: [
    // Setup authentication
    { name: 'setup', testMatch: /.*\.setup\.ts/ },

    // Desktop browsers
    {
      name: 'chromium',
      use: {
        ...devices['Desktop Chrome'],
        storageState: 'tests/playwright/.auth/user.json',
      },
      dependencies: ['setup'],
    },

    {
      name: 'firefox',
      use: {
        ...devices['Desktop Firefox'],
        storageState: 'tests/playwright/.auth/user.json',
      },
      dependencies: ['setup'],
    },

    // Mobile browsers
    {
      name: 'mobile-chrome',
      use: {
        ...devices['Pixel 5'],
        storageState: 'tests/playwright/.auth/user.json',
      },
      dependencies: ['setup'],
    },
  ],

  webServer: {
    command: 'pnpm dev',
    url: 'http://localhost:3000',
    reuseExistingServer: !process.env.CI,
  },
});
```

#### `.gitignore` updates
```
# Playwright
tests/playwright/.auth/
test-results/
playwright-report/
playwright/.cache/
```

### 2. Authentication Setup

#### `tests/playwright/auth.setup.ts`
```typescript
import { test as setup, expect } from '@playwright/test';

const authFile = 'tests/playwright/.auth/user.json';

setup('authenticate', async ({ page }) => {
  // Check if auth already exists and is valid
  const authCookie = process.env.PLAYWRIGHT_AUTH_COOKIE;

  if (authCookie) {
    // Use existing auth from environment
    await page.context().addCookies([{
      name: 'ponderants-auth',
      value: authCookie,
      domain: 'localhost',
      path: '/',
    }]);
  } else {
    // Perform OAuth login
    await page.goto('/');
    await page.click('text=Log in with Bluesky');

    // Wait for OAuth redirect
    await page.waitForURL(/bsky\.social/);

    // Fill in credentials
    await page.fill('input[name="identifier"]', process.env.TEST_USER_HANDLE!);
    await page.fill('input[name="password"]', process.env.TEST_USER_PASSWORD!);
    await page.click('button[type="submit"]');

    // Wait for redirect back to app
    await page.waitForURL(/localhost:3000/);

    // Verify we're authenticated
    await expect(page.getByRole('button', { name: /profile/i })).toBeVisible();
  }

  // Save signed-in state
  await page.context().storageState({ path: authFile });
});
```

### 3. Test Fixtures and Helpers

#### `tests/playwright/fixtures.ts`
```typescript
import { test as base, Page } from '@playwright/test';

type Fixtures = {
  authenticatedPage: Page;
  chatPage: Page;
  galaxyPage: Page;
};

export const test = base.extend<Fixtures>({
  authenticatedPage: async ({ page }, use) => {
    // Already authenticated via setup
    await page.goto('/');
    await use(page);
  },

  chatPage: async ({ page }, use) => {
    await page.goto('/chat');
    await use(page);
  },

  galaxyPage: async ({ page }, use) => {
    await page.goto('/galaxy');
    await use(page);
  },
});

export { expect } from '@playwright/test';
```

#### `tests/playwright/helpers/chat.ts`
```typescript
import { Page, expect } from '@playwright/test';

export class ChatHelper {
  constructor(private page: Page) {}

  async sendMessage(message: string) {
    await this.page.fill('textarea[placeholder*="Type"]', message);
    await this.page.press('textarea[placeholder*="Type"]', 'Enter');
  }

  async waitForAIResponse() {
    // Wait for typing indicator to disappear
    await this.page.waitForSelector('[data-testid="typing-indicator"]', {
      state: 'hidden',
      timeout: 30000,
    });
  }

  async createNode() {
    await this.page.click('button:has-text("Create Node")');
  }

  async getLastMessage() {
    const messages = this.page.locator('[data-testid="chat-message"]');
    const count = await messages.count();
    return messages.nth(count - 1);
  }
}
```

#### `tests/playwright/helpers/galaxy.ts`
```typescript
import { Page, expect } from '@playwright/test';

export class GalaxyHelper {
  constructor(private page: Page) {}

  async waitForGalaxyLoad() {
    // Wait for canvas to be visible
    await this.page.waitForSelector('canvas', { timeout: 10000 });

    // Wait for nodes to be loaded (check for at least one node)
    await this.page.waitForFunction(() => {
      const canvas = document.querySelector('canvas');
      return canvas && canvas.getContext('2d') !== null;
    });
  }

  async clickNode(nodeId: string) {
    // Find and click on a specific node
    await this.page.evaluate((id) => {
      const event = new CustomEvent('node-click', { detail: { nodeId: id } });
      window.dispatchEvent(event);
    }, nodeId);
  }

  async getNodeCount() {
    return await this.page.evaluate(() => {
      // Access R3F scene data
      return window.__galaxyNodes?.length || 0;
    });
  }
}
```

#### `tests/playwright/helpers/node.ts`
```typescript
import { Page, expect } from '@playwright/test';

export class NodeHelper {
  constructor(private page: Page) {}

  async createNode(title: string, body: string) {
    // Navigate to chat
    await this.page.goto('/chat');

    // Trigger node creation
    await this.page.fill('input[placeholder*="Title"]', title);
    await this.page.fill('textarea[placeholder*="Body"]', body);
    await this.page.click('button:has-text("Publish")');

    // Wait for success
    await expect(this.page.getByText(/published/i)).toBeVisible();
  }

  async waitForUMAPCalculation() {
    // Poll /api/galaxy until nodes have coords_3d
    await this.page.waitForFunction(async () => {
      const response = await fetch('/api/galaxy');
      const data = await response.json();
      return data.nodes.every((n: any) => n.coords_3d !== null);
    }, { timeout: 60000 });
  }
}
```

### 4. Example Tests

#### `tests/playwright/smoke.spec.ts`
```typescript
import { test, expect } from './fixtures';

test.describe('Smoke Tests', () => {
  test('homepage loads', async ({ page }) => {
    await page.goto('/');
    await expect(page).toHaveTitle(/Ponderants/);
  });

  test('authenticated user can access chat', async ({ chatPage }) => {
    await expect(chatPage.getByRole('textbox')).toBeVisible();
  });

  test('authenticated user can access galaxy', async ({ galaxyPage }) => {
    await expect(galaxyPage.locator('canvas')).toBeVisible();
  });
});
```

### 5. Environment Variables

#### `.env.test` (template)
```bash
# Test user credentials
TEST_USER_HANDLE=your-test-handle.bsky.social
TEST_USER_PASSWORD=your-test-password

# Optional: Pre-authenticated cookie for faster tests
PLAYWRIGHT_AUTH_COOKIE=

# Playwright settings
PLAYWRIGHT_BASE_URL=http://localhost:3000
```

## Implementation Steps

1. **Create directory structure**
   ```bash
   mkdir -p tests/playwright/.auth
   mkdir -p tests/playwright/helpers
   ```

2. **Install dependencies**
   ```bash
   pnpm add -D @playwright/test
   ```

3. **Create configuration files**
   - playwright.config.ts
   - .gitignore updates
   - .env.test template

4. **Create authentication setup**
   - auth.setup.ts

5. **Create fixtures and helpers**
   - fixtures.ts
   - helpers/chat.ts
   - helpers/galaxy.ts
   - helpers/node.ts

6. **Create example tests**
   - smoke.spec.ts

7. **Update package.json scripts**
   ```json
   {
     "scripts": {
       "test:playwright": "playwright test",
       "test:playwright:ui": "playwright test --ui",
       "test:playwright:debug": "playwright test --debug"
     }
   }
   ```

## Testing Plan

### Manual Playwright MCP Testing
1. Open Playwright MCP browser
2. Navigate to http://localhost:3000
3. Test authentication flow
4. Test chat interaction
5. Test node creation
6. Test galaxy visualization
7. Test node detail modal

### Magnitude Test Integration
After manual testing succeeds, create magnitude tests that use the same patterns:

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

test('User can create and view nodes in galaxy', async (agent) => {
  await agent.open('http://localhost:3000');
  await agent.act('Log in with test credentials');
  await agent.check('User is authenticated');

  await agent.act('Navigate to chat');
  await agent.act('Create a new node with title "Test Node" and body "Test content"');
  await agent.check('Node is published to Bluesky');

  await agent.act('Navigate to galaxy');
  await agent.check('Can see the new node in 3D visualization');
});
```

## Success Criteria

- ✅ Playwright configuration file exists
- ✅ Authentication setup works (both OAuth and cookie-based)
- ✅ Helper classes for chat, galaxy, and node operations exist
- ✅ Example smoke tests pass
- ✅ Can run `pnpm test:playwright` successfully
- ✅ Manual Playwright MCP testing is efficient with helpers
- ✅ Foundation exists for Magnitude test creation
