Supported browsers

  • Chromium (default). Fast and lightweight, but missing some features of full Chrome (e.g. H.264 video playback). May be unstable on graphics-heavy sites.
  • Google Chrome. Full-featured Chrome with H.264, media streaming, WebGL. Heavier and slower than Chromium.
  • Chrome for Testing. Chrome for Testing is maintained by Google specifically for automation.

Choosing a browser

Set a project-wide default in momentic.config.yaml:
momentic.config.yaml
browser:
  defaultBrowserType: Chromium
Individual tests override the default from Test options in the editor. See browser.defaultBrowserType for the full list of accepted values.
