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(condition, timeout, timeoutMsg, interval)

Parameters

Name	Type	Details
condition	Function	condition to wait on
timeout optional	Number, undefined	timeout in ms (default: 5000)
timeoutMsg optional	String, undefined	error message to throw when waitUntil times out
interval optional	Number, undefined	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(() => {
      return $('#someText').getText() === 'I am now different'
    }, 5000, 'expected text to be different after 5s');
});
