BrowserConnection.ready Event

Fires when a remote browser connects to the TestCafe server.

browserConnection.once('ready', callback)

You can run tests without waiting for the ready event to fire. The method automatically waits for all browser connections to be established. If remote browsers do not connect within 30 seconds, TestCafe throws an error. Wait for the ready event only when there is a chance that a remote connection takes longer than 30 seconds to be established.
