Playwright enables reliable end-to-end testing for modern web apps.

• Testing that PWAs work offline using Playwright
• Run an X11 display server and noVNC on Codespaces — for debugging Playwright tests in GitHub Codespaces
• How I structure Playwright page objects

Notes

• Test debugging configuration:

    use: {
      // Disable tracing when running locally,
      // as it breaks the "Show & Reuse Browser" feature.
      trace: process.env.CI ? 'retain-on-failure' : 'on-first-retry',
  
      video: process.env.CI ? 'on' : 'off',
      screenshot: process.env.CI ? 'on' : 'off',
    }

• Web server configuration:

    webServer: {
      command: 'yarn start -p 2022',
      port: 2022,
      // Do not start a server if it is already running locally.
      reuseExistingServer: !process.env.CI,
    },
