end

.create(playwright_cli_executable_path:, &block) ⇒ Object

Recommended to call this method with block.

Playwright.create(…) do |playwright|

browser = playwright.chromium.launch
...

end

When we use this method without block, an instance of Playwright::Execution is returned and we must call execution.stop on the end. The instance of playwright is available by calling execution.playwright
