puppeteer/test/elementhandle.spec.js
Maja Frydrychowicz 3d56a9e76f chore: add test configuration options for running tests against multiple products (#5964)
* chore: remove "Extracting..." log message

Fixes #5741.

* test: support extra Launcher options and skips

The extra Launcher options and skipping conditions enable
unit tests to be run more easily by third-parties, e.g.
browser vendors that are interested in Puppeteer support.

Extra Launcher options were previously removed as part of
switching away from the custom test harness.

* test: enable more tests for Firefox
