[Question]WebKit version

[dave-hart]

Hi,

How do I link back the WebKit version packaged with playwright to that used in my Safari browser?

I am finding lots of different representations of WebKit versions when I attempt to figure this out
Playwright Specify 14.2 on their Readme
The about box on my stock Safari install states 610.4.3.1.4
The Downloads page on the WebKit site just has a 5 digit number

In order for WebKit to be a viable replacement for Safari and WebDriver, I need to be able to identify exactly what I am testing against. This came about as I am seeing bugs in my local stock Safari install, that do not appear in tests against WebKit. I suspect it's a versioning issue, but without being able to see versions I cannot say for sure.

Many thanks

The version listed in our README.md corresponds to the 'Version/<x.y.z>" part in the user agent string (and displayed in about safari dialog):
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.2 Safari/605.1.15"

14.2 corresponds to the version currently used in Safari Technology Preview. There might be some slight differences between the private build of webkit and playwright build which includes only the open-source part. Also webkit revision which is used in playwright may be a bit ahead of the version used in the technology preview (e.g. 1.9.2 is based on 274075 while Safari Tech Preview 121 uses 272845).

@yury-s Thank you for your answer.

How is browser versioning managed in Playwright? Do we get a particular version of all three browsers at the time we fetch Playwright from npm, or does Playwright dynamically fetch newer versions at runtime?

Release notes point to the exact versions of the browsers used: https://github.com/microsoft/playwright/releases

Each Plawright version comes with a fixed version of each browser, the browsers are downloaded when you run npm install.
