[Feature] Front-end performance testing

See original GitHub issue

It would be great if Playwright could do front-end performance testing using something like Google Lighthouse. For example, Cypress has cypress-audit. Something similar where we can run a test and assert the metrics would be great to do with Playwright.

@nadvolod It would be awesome if you would like to build a convenient integration! If you could publish it to share with anyone else that needs it, that would be even better 😄

It is not a top priority for Playwright to include such a feature right now, but I’ll leave this feature request open for future prioritization.

@pavelfeldman good to know about the initial Cypress navigation, thanks for pointing that out 👍

Yes, a test runner + Lighthouse integration. The issue for me with direct Lighthouse integration is that it’s not automated. Looks like I could manually construct my assertions on the result of the await lighthouse('https://example.com', options); . However, seems more difficult than just calling a function with some pre-configured behavior. I can build that function myself or Playwright can build it into its capabilities and have that as a feature to benefit the entire community. Wdyt?
