Defined in:

Overview

BrowserType provides methods to launch a specific browser instance or connect to an existing one. The following is a typical example of using Playwright to drive automation:

“‘python sync from playwright.sync_api import sync_playwright

def run(playwright):

chromium = playwright.chromium
browser = chromium.launch()
page = browser.new_page()
page.goto("https://example.com")
# other actions...
browser.close()

with sync_playwright() as playwright:

run(playwright)

“‘

Instance Method Details

#connect(wsEndpoint, headers: nil, slowMo: nil, timeout: nil) ⇒ Object

This methods attaches Playwright to an existing browser instance.

Raises:

  • (NotImplementedError)

# File 'lib/playwright_api/browser_type.rb', line 22

def connect(wsEndpoint, headers: nil, slowMo: nil, timeout: nil)
  raise NotImplementedError.new('connect is not implemented yet.')
end

#connect_over_cdp(endpointURL, headers: nil, slowMo: nil, timeout: nil, &block) ⇒ Object

This methods attaches Playwright to an existing browser instance using the Chrome DevTools Protocol.

The default browser context is accessible via [‘method: Browser.contexts`].

> NOTE: Connecting over the Chrome DevTools Protocol is only supported for Chromium-based browsers.

end

#executable_path ⇒ Object

A path where Playwright expects to find a bundled browser executable.

def executable_path
  wrap_impl(@impl.executable_path)

Returns the browser instance.

You can use ignoreDefaultArgs to filter out --mute-audio from default arguments:

“‘python sync browser = playwright.chromium.launch( # or “firefox” or “webkit”.

ignore_default_args=["--mute-audio"]

) “‘

> Chromium-only Playwright can also be used to control the Google Chrome or Microsoft Edge browsers, but it works best with the version of Chromium it is bundled with. There is no guarantee it will work with any other version. Use executablePath option with extreme caution. > > If Google Chrome (rather than Chromium) is preferred, a [Chrome Canary](www.google.com/chrome/browser/canary.html) or [Dev Channel](www.chromium.org/getting-involved/dev-channel) build is suggested. > > Stock browsers like Google Chrome and Microsoft Edge are suitable for tests that require proprietary media codecs for video playback. See [this article](www.howtogeek.com/202825/what%E2%80%99s-the-difference-between-chromium-and-chrome/) for other differences between Chromium and Chrome. [This article](chromium.googlesource.com/chromium/src/+/lkgr/docs/chromium_browser_vs_google_chrome.md) describes some differences for Linux users.

Returns the persistent browser context instance.

Launches browser that uses persistent storage located at userDataDir and returns the only context. Closing this context will automatically close the browser.

Raises:

  • (NotImplementedError)
