class Playwright::WebSocket

The ‘WebSocket` class represents websocket connections in the page.

def closed?

Indicates that the web socket has been closed.

value. Will throw an error if the webSocket is closed before the event is fired. Returns the event data value.
Waits for event to fire and passes its value into the predicate function. Returns when the predicate returns truthy

def wait_for_event(event, predicate: nil, timeout: nil, &block)

Will throw an error if the socket is closed before the `event` is fired.
event's value into the `predicate` function and waits for `predicate(event)` to return a truthy value.
Waits for given `event` to fire. If predicate is provided, it passes

**NOTE**: In most cases, you should use [`method: WebSocket.waitForEvent`].
