I'm testing my application's frontend behavior in multi-browser and multi-version environment. I chose playwright because it supports those environments.
Now, I'm trying to test older versions of webkit. For that, I need to install the older versions first. However, I cannot find the older versions of webkit, and also current version.
Playwright's doc says that they are currently using "WebKit 17.0", but there is no such thing as 'Webkit 17.0'.
I looked up webkit release archives, but I couldn't find any "17.0".
There is no much information about webkit versioning, but according to this issue, the "WebKit version" in playwright means the Version value from Safari's user-agent. The contributer says that "version" corresponds to the version currently used in Safari Techonology Preview, and release Notes for Safari Technology Preview says it covers certain range of webkit revisions.
I guess I should build it myself if I want to test older version of webkit, or I can install multiple versions of playwright.
