[Feature] Browser.version()

[DJ-Glock]

Hello.
I would like to log browser version that is used for testing.
In puppeteer there was a function:
browser.version()
But I was not able to find similar func in Playwright.

Is there any other way to get browser version?

A chromium specific way would be currently something like that. This is the same what Puppeteer was doing:

// @ts-check
const playwright = require("playwright");

(async () => {
  const browser = await playwright.chromium.launch();
  const session = await browser.newBrowserCDPSession();
  const version = await session.send('Browser.getVersion');
  console.log(version.product);
  // HeadlessChrome/85.0.4165.0
  await session.detach();
})();

Currently there is no way to get he browser versions for all of the browser except a User-Agent is enough for you:

// @ts-check
const playwright = require("playwright");

(async () => {
  // Try to add 'firefox' to the list ↓
  for (const browserType of ['chromium', 'webkit', 'firefox']) {
    /** @type {import('playwright').Browser} */
    const browser = await playwright[browserType].launch();
    const context = await browser.newContext();
    const page = await context.newPage();
    console.log(await page.evaluate(() => navigator.userAgent));
    await browser.close();
  }
})();

This would lead to that:

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/85.0.4165.0 Safari/537.36
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.2 Safari/605.1.15
Mozilla/5.0 (X11; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0

It would be nice to have the browser.version() function across all browsers.

@mxschmitt thanks a lot!

For my case it's enough. But it would be really nice to have browser.version) for all browsers.
Can this issue be transformed to Feature Request?

Team,
Please correct me if I am wrong but

• Google Chrome Protocol has such method Browser.getVersion
• Firefox remote debugging protocol does not have such method. Search link
• For Safari it is also challenging to find

We had it, but got rid of it - did not have a use case for it. Logging seems to be a valid one, we can bring it back.

There is no such thing as a WebKit version, so we use a matching Safari version for it. For the others, we can get an official one.

@amartyushov : confirming for CDT, we don't use FF's RDP, confirming for WebKit remote protocol.
