new tests that work with WebDriver BiDi and that didn' t work with CDP.< / p > < p > For Chrome, around 68% of the tests are currently passing with WebDriver BiDi so
the CDP-based implementation remains more powerful. Some of the Puppeteer
functionality is relying on CDP even with WebDriver BiDi enabled. Therefore, the
