Cypress to Playwright Migration Plan¶

Status: In Progress

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

Goal: Migrate all 25 Cypress E2E tests to Playwright for faster execution and better multi-browser support.

Architecture: Port tests iteratively by suite, maintaining Cypress in parallel until migration is complete. Create shared Playwright fixtures/helpers mirroring Cypress patterns, then convert each test file preserving exact test coverage.

Tech Stack: Playwright 1.58+, TypeScript, existing backend test API endpoints

Review Feedback (Incorporated)¶

QA Engineer Review: - GitHub Actions workflow needs Docker stack for full E2E tests - ~~Clarify directory numbering (10-herodraft vs 11-herodraft)~~ RESOLVED: Consolidated to 11-herodraft/ - Address parallel test isolation concerns for stateful tests - Add WebSocket utility for Channels tests - Keep Cypress functional until 100% parity reached

DevOps Engineer Review: - Use test.playwright.* namespace (not test.runner.playwright.*) - Reuse existing flush_test_redis() function - Fix herodraft spec pattern to match actual directory

TypeScript Engineer Review: - Create Page Object classes (TournamentPage, LeaguePage) for consistency - Use project-based parallelism (parallel for general, sequential for herodraft) - Use explicit waits instead of waitForTimeout() where possible

Task 1: Expand Playwright Config for Full E2E Suite¶

Files: - Modify: frontend/playwright.config.ts

Step 1: Update playwright.config.ts for parallel test execution

import { defineConfig, devices } from '@playwright/test';

/**
 * Playwright configuration for E2E tests.
 * Migrated from Cypress for faster parallel execution.
 */
export default defineConfig({
  testDir: './tests/playwright',
  fullyParallel: true, // Enable parallel execution
  forbidOnly: !!process.env.CI,
  retries: process.env.CI ? 2 : 0,
  workers: process.env.CI ? 4 : undefined, // 4 workers in CI, auto in local
  reporter: [
    ['html', { open: 'never' }],
    ['list'],
    ...(process.env.CI ? [['github' as const]] : []),
  ],

  use: {
    baseURL: 'https://localhost',
    trace: 'on-first-retry',
    screenshot: 'only-on-failure',
    video: 'retain-on-failure',
    ignoreHTTPSErrors: true, // For self-signed certs in dev

    // Default viewport (matches Cypress config)
    viewport: { width: 1280, height: 720 },
  },

  projects: [
    {
      name: 'chromium',
      use: {
        ...devices['Desktop Chrome'],
        launchOptions: {
          args: [
            '--disable-web-security',
            '--disable-features=IsolateOrigins,site-per-process',
            '--disable-gpu',
            '--disable-dev-shm-usage',
          ],
        },
      },
    },
    // Add mobile project for responsive tests
    {
      name: 'mobile-chrome',
      use: {
        ...devices['Pixel 5'],
      },
    },
  ],

  // Global timeout (matches Cypress pageLoadTimeout)
  timeout: 30_000,

  // Expect timeout (matches Cypress defaultCommandTimeout)
  expect: {
    timeout: 10_000,
  },
});

Step 2: Verify config is valid

Run: cd /home/kettle/git_repos/website/.worktrees/herodraft/frontend && npx playwright test --list Expected: Lists available tests without errors

Step 3: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/playwright.config.ts
git commit -m "feat(tests): expand playwright config for full e2e migration"

Task 2: Create Shared Playwright Utilities¶

Files: - Create: frontend/tests/playwright/helpers/utils.ts

Step 1: Port hydration and navigation utilities from Cypress

import { Page, Locator, expect } from '@playwright/test';

/**
 * Utilities for handling React hydration and common test patterns.
 * Ported from Cypress support/utils.ts
 */

/**
 * Visit a page and wait for React hydration to complete.
 */
export async function visitAndWaitForHydration(page: Page, url: string): Promise<void> {
  await page.goto(url);

  // Wait for the page to be visible
  await page.locator('body').waitFor({ state: 'visible' });

  // Wait for document ready state
  await page.waitForFunction(() => document.readyState === 'complete');

  // Wait for React app indicators
  await page
    .locator('[data-slot], nav, main, #root')
    .first()
    .waitFor({ state: 'visible', timeout: 10000 });

  // Brief wait for React hydration
  await page.waitForTimeout(200);
}

/**
 * Wait for any loading states to complete.
 */
export async function waitForLoadingToComplete(page: Page): Promise<void> {
  const loadingIndicators = page.locator('[data-testid="loading"], .loading, .spinner');

  // If loading indicators exist, wait for them to disappear
  const count = await loadingIndicators.count();
  if (count > 0) {
    await loadingIndicators.first().waitFor({ state: 'hidden', timeout: 10000 });
  }
}

/**
 * Smart navigation that handles both visible links and dropdown menus.
 */
export async function navigateToRoute(page: Page, route: string): Promise<void> {
  // First try visible navigation links
  const visibleSelectors = [
    `nav > a[href="${route}"]`,
    `header a[href="${route}"]`,
    `.navbar a[href="${route}"]`,
    `a[href="${route}"]`,
  ];

  for (const selector of visibleSelectors) {
    const link = page.locator(selector).first();
    if (await link.isVisible().catch(() => false)) {
      await link.click();
      return;
    }
  }

  // Try dropdown navigation
  const dropdownTriggers = [
    'button[aria-haspopup="true"]',
    '.dropdown-toggle',
    '.menu-button',
    '[data-testid="menu-button"]',
    '.hamburger-menu',
    'button[aria-label="Open mobile menu"]',
  ];

  for (const triggerSelector of dropdownTriggers) {
    const trigger = page.locator(triggerSelector).first();
    if (await trigger.isVisible().catch(() => false)) {
      await trigger.click();
      await page.waitForTimeout(300);

      const link = page.locator(`a[href="${route}"]`).first();
      if (await link.isVisible().catch(() => false)) {
        await link.click();
        return;
      }
    }
  }

  // Fallback: direct navigation
  await visitAndWaitForHydration(page, route);
}

/**
 * Check for basic accessibility features.
 */
export async function checkBasicAccessibility(page: Page): Promise<void> {
  // Check language attribute
  await expect(page.locator('html')).toHaveAttribute('lang', /.+/);

  // Check for title
  const title = await page.title();
  expect(title.length).toBeGreaterThan(0);

  // Check for main content landmark
  const mainLandmark = page.locator('main, [role="main"]');
  const hasMain = await mainLandmark.count() > 0;
  if (!hasMain) {
    console.log('No main landmark found - this could be improved for accessibility');
  }
}

/**
 * Suppress hydration errors in console (for debugging).
 * In Playwright, we handle this differently - we just ignore known error patterns.
 */
export const IGNORED_CONSOLE_PATTERNS = [
  'Hydration failed',
  'Text content does not match',
  'Warning: Text content did not match',
  "server rendered HTML didn't match",
  'Expected server HTML to contain',
  'net::ERR_ABORTED',
  'Failed to load resource',
  'fonts.googleapis.com',
  'ResizeObserver loop',
];

/**
 * Check if a console message should be ignored.
 */
export function shouldIgnoreConsoleMessage(message: string): boolean {
  return IGNORED_CONSOLE_PATTERNS.some(pattern =>
    message.toLowerCase().includes(pattern.toLowerCase())
  );
}

Step 2: Verify the file compiles

Run: cd /home/kettle/git_repos/website/.worktrees/herodraft/frontend && npx tsc --noEmit tests/playwright/helpers/utils.ts Expected: No errors

Step 3: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/tests/playwright/helpers/utils.ts
git commit -m "feat(tests): add playwright shared utilities ported from cypress"

Task 3: Create Playwright Helper Functions for Users¶

Files: - Create: frontend/tests/playwright/helpers/users.ts

Step 1: Port user helpers from Cypress

import { Page, Locator } from '@playwright/test';

/**
 * User-related test helpers.
 * Ported from Cypress helpers/users.ts
 */

/**
 * Get a user card element by username.
 */
export function getUserCard(page: Page, username: string): Locator {
  return page.locator(`[data-testid="usercard-${username}"]`);
}

/**
 * Get the remove player button for a specific user.
 */
export function getUserRemoveButton(page: Page, username: string): Locator {
  return page.locator(`[data-testid="removePlayerBtn-${username}"]`);
}

/**
 * Wait for a user card to be visible.
 */
export async function waitForUserCard(page: Page, username: string): Promise<void> {
  await getUserCard(page, username).waitFor({ state: 'visible' });
}

/**
 * Click the remove button for a user.
 */
export async function removeUser(page: Page, username: string): Promise<void> {
  await getUserRemoveButton(page, username).click();
}

Step 2: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/tests/playwright/helpers/users.ts
git commit -m "feat(tests): add playwright user helpers"

Task 4: Create Playwright Tournament Helpers¶

Files: - Create: frontend/tests/playwright/helpers/tournament.ts - Reference: frontend/tests/cypress/helpers/tournament.ts

Step 1: Read existing Cypress tournament helpers and port

First read the existing file, then create the Playwright equivalent with the same functionality.

import { Page, Locator, BrowserContext, expect } from '@playwright/test';

const API_URL = 'https://localhost/api';

/**
 * Tournament-related test helpers.
 * Ported from Cypress helpers/tournament.ts
 */

export interface TournamentData {
  pk: number;
  name: string;
  teams: Array<{
    pk: number;
    name: string;
    captain: {
      pk: number;
      username: string;
    };
    draft_order: number;
  }>;
  captains: Array<{
    pk: number;
    username: string;
  }>;
}

/**
 * Get tournament details by test config key.
 */
export async function getTournamentByKey(
  context: BrowserContext,
  key: string
): Promise<TournamentData> {
  const response = await context.request.get(
    `${API_URL}/tests/tournament-by-key/${key}/`
  );
  expect(response.ok()).toBeTruthy();
  return response.json();
}

/**
 * Navigate to a tournament page.
 */
export async function navigateToTournament(page: Page, tournamentPk: number): Promise<void> {
  await page.goto(`/tournament/${tournamentPk}`);
  await page.locator('body').waitFor({ state: 'visible' });
}

/**
 * Click on the Teams tab in a tournament.
 */
export async function clickTeamsTab(page: Page): Promise<void> {
  await page.locator('text=/Teams \\(\\d+\\)/').click();
  await page.waitForTimeout(500);
}

/**
 * Click the Start Draft button.
 */
export async function clickStartDraft(page: Page): Promise<void> {
  const startDraftBtn = page.locator('button:has-text("Start Draft"), button:has-text("Live Draft")');
  await startDraftBtn.first().click();
  await page.waitForTimeout(500);
}

/**
 * Wait for the draft modal to open.
 */
export async function waitForDraftModal(page: Page): Promise<Locator> {
  const modal = page.locator('[role="dialog"]');
  await modal.waitFor({ state: 'visible' });
  return modal;
}

Step 2: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/tests/playwright/helpers/tournament.ts
git commit -m "feat(tests): add playwright tournament helpers"

Task 5: Create Playwright League Helpers¶

Files: - Create: frontend/tests/playwright/helpers/league.ts - Reference: frontend/tests/cypress/helpers/league.ts

Step 1: Read existing Cypress league helpers and port

import { Page, Locator, BrowserContext, expect } from '@playwright/test';

const API_URL = 'https://localhost/api';

/**
 * League-related test helpers.
 * Ported from Cypress helpers/league.ts
 */

export interface LeagueData {
  pk: number;
  name: string;
  // Add other fields as needed based on actual league structure
}

/**
 * Navigate to a league page.
 */
export async function navigateToLeague(page: Page, leaguePk: number): Promise<void> {
  await page.goto(`/league/${leaguePk}`);
  await page.locator('body').waitFor({ state: 'visible' });
}

/**
 * Click on a league tab by name.
 */
export async function clickLeagueTab(page: Page, tabName: string): Promise<void> {
  await page.locator(`[role="tab"]:has-text("${tabName}")`).click();
  await page.waitForTimeout(300);
}

/**
 * Get league edit modal.
 */
export function getLeagueEditModal(page: Page): Locator {
  return page.locator('[role="dialog"]');
}

/**
 * Open league edit modal.
 */
export async function openLeagueEditModal(page: Page): Promise<Locator> {
  await page.locator('button:has-text("Edit")').click();
  const modal = getLeagueEditModal(page);
  await modal.waitFor({ state: 'visible' });
  return modal;
}

Step 2: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/tests/playwright/helpers/league.ts
git commit -m "feat(tests): add playwright league helpers"

Task 6: Update Playwright Fixtures Index¶

Files: - Modify: frontend/tests/playwright/fixtures/index.ts

Step 1: Export all helpers from index

/**
 * Playwright Test Fixtures
 *
 * Export all fixtures for easy importing in tests.
 */

// Auth utilities (functions only, not the extended test)
export {
  loginAsUser,
  loginAsDiscordId,
  loginAdmin,
  loginStaff,
  loginUser,
  waitForHydration,
  visitAndWait,
  type UserInfo,
  type LoginResponse,
} from './auth';

// HeroDraft utilities
export {
  getHeroDraftByKey,
  resetHeroDraft,
  createTestHeroDraft,
  setupTwoCaptains,
  positionWindowsSideBySide,
  type HeroDraftInfo,
  type CaptainContext,
} from './herodraft';

// Re-export the extended test from auth (primary test fixture)
export { test, expect } from './auth';

// Re-export helpers
export * from '../helpers/utils';
export * from '../helpers/users';
export * from '../helpers/tournament';
export * from '../helpers/league';

Step 2: Commit

cd /home/kettle/git_repos/website/.worktrees/herodraft
git add frontend/tests/playwright/fixtures/index.ts
git commit -m "feat(tests): update playwright fixtures index with all helpers"

Task 7: Create Invoke Task for Playwright Runner¶

Files: - Create: frontend/tests/playwright/e2e/01-navigation.spec.ts - Reference: frontend/tests/cypress/e2e/01-navigation.cy.ts

Step 1: Create the navigation test file

import { test, expect } from '@playwright/test';
import {
  visitAndWaitForHydration,
  checkBasicAccessibility,
  navigateToRoute,
} from '../../fixtures';

test.describe('Navigation and Basic Functionality', () => {
  test.beforeEach(async ({ page }) => {

        const bodyWidth = await page.evaluate(() => document.body.scrollWidth);
        expect(bodyWidth).toBeLessThanOrEqual(viewport.width + 1);
      }
    }
  });

  test('should handle 404 pages gracefully', async ({ page }) => {
    await page.goto('/non-existent-page');

    // Should show some kind of error page or redirect

    const margin = await page.locator('body').evaluate(el =>
      window.getComputedStyle(el).margin

    await expect(page).toHaveURL(/\/$/);

    // Use browser forward button
    await page.goForward();
    await expect(page).toHaveURL(/\/tournaments/);
  });
});

Step 2: Run the test to verify it compiles

Run: cd /home/kettle/git_repos/website/.worktrees/herodraft/frontend && npx playwright test tests/playwright/e2e/01-navigation.spec.ts --list Expected: Lists the test cases

## Testing

**Backend (via Docker - Recommended)**:
```bash
source .venv/bin/activate
inv test.run --cmd 'python manage.py test app.tests -v 2'

Frontend E2E (Playwright - Recommended):

source .venv/bin/activate

# Run all Playwright tests
inv test.runner.playwright.headless

# Run with UI mode (interactive)
inv test.runner.playwright.ui

# Run specific suite
inv test.runner.playwright.spec --spec navigation
inv test.runner.playwright.spec --spec tournament
inv test.runner.playwright.spec --spec draft

# Run herodraft tests
inv test.runner.playwright.herodraft

Frontend E2E (Cypress - Legacy):

source .venv/bin/activate
inv test.open          # Cypress interactive
inv test.headless      # Cypress headless

**Step 2: Commit**

```bash
cd /home/kettle/git_repos/website/.worktrees/herodraft
git add .claude/CLAUDE.md docs/dev/testing/
git commit -m "docs: update testing documentation for playwright migration"

`cy.get(sel).type(text)`	`await page.locator(sel).fill(text)`
`cy.get(sel).should('be.visible')`	`await expect(page.locator(sel)).toBeVisible()`
`cy.get(sel).should('contain.text', 'x')`	`await expect(page.locator(sel)).toContainText('x')`
`cy.get(sel).should('have.attr', 'x')`	`await expect(page.locator(sel)).toHaveAttribute('x', /.+/)`

`cy.intercept(...)`	`await page.route(...)`
`cy.viewport(w, h)`	`await page.setViewportSize({ width: w, height: h })`
`cy.go('back')`	`await page.goBack()`
`cy.go('forward')`	`await page.goForward()`
`cy.title()`	`await page.title()`
`beforeEach(() => {...})`	`test.beforeEach(async ({ page }) => {...})`
`describe('...', () => {...})`	`test.describe('...', () => {...})`
`it('...', () => {...})`	`test('...', async ({ page }) => {...})`
`cy.contains('text')`	`page.locator('text=text')` or `page.getByText('text')`
`cy.get('[data-testid="x"]')`	`page.getByTestId('x')`

Summary¶

Total Tasks: 21 Test Files to Port: 25 Estimated Implementation: Tasks 1-8 create infrastructure, Tasks 9-18 port tests

After completing all tasks, the Cypress tests can be deprecated (kept for reference initially) and eventually removed from the codebase.
