waitUntil
This wait command is your universal weapon if you want to wait on something. It expects a condition and waits until that condition is fulfilled with a truthy value.
اطلاعات
As opposed to other element commands WebdriverIO will not wait for the element to exist to execute this command.
A common example is to wait until a certain element contains a certain text (see example).
Usage
$(selector).waitUntil(condition, { timeout, timeoutMsg, interval })
