waitForExist

Wait for an element for the provided amount of milliseconds to be present within the DOM. Returns true if the selector matches at least one element that exists in the DOM, otherwise throws an error. If the reverse flag is true, the command will instead return true if the selector does not match any elements.

தகவல்

As opposed to other element commands WebdriverIO will not wait for the element to exist to execute this command.

Usage
$(selector).waitForExist({ timeout, reverse, timeoutMsg, interval })

await notification.waitForExist({ timeout: 5000 });
