Playwright inspector

Playwright provides an useful inspector. https://playwright.dev/docs/inspector/

Overview

playwright.chromium.launch(headless: false) do |browser|
  browser.new_context do |context|
    # This method call should be put just after creating BrowserContext.
    context.enable_debug_console!

    page = context.new_pagè
    page.goto('http://example.com/')
    page.pause
  end
end

page.pause requires Playwright debug session, and it can be enabled by calling BrowserContext#enable_debug_console! in advance.

Note that since Ruby is not officially supported in Playwright, many limitations exist. We CANNOT

Launch inspector via PWDEBUG=1
Debug without inspector UI (PWDEBUG=console is not working well)
Show Ruby code in inspector
