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. If you use the WDIO testrunner the commands within the condition are getting executed synchronously like in your test.

A common example is to wait until a certain element contains a certain text (see example).

Usage

browser.waitUntil({ options, timeout, timeoutMsg, interval })

Parameters

Name	Type	Details
condition	?	condition to wait on
options optional	WaitUntilOptions	command options
options.timeout optional	Number	timeout in ms (default: 5000)
options.timeoutMsg optional	String	error message to throw when waitUntil times out
options.interval optional	Number	interval between condition checks (default: 500)

Examples

<div id="someText">I am some text</div>
<script>
  setTimeout(() => {
    $('#someText').html('I am now different');
  }, 1000);
</script>

it('should wait until text has changed', () => {
    browser.waitUntil(
        () => $('#someText').getText() === 'I am now different',
        {
            timeout: 5000,
            timeoutMsg: 'expected text to be different after 5s'
        }
    );
});
