Testing popups and other interactions
So for example let's say we would like to test a popup on site https://jqueryui.com/dialog/#modal-form.
to your project's setting:
So then after taking a screenshot they will have a popup rendered. See example screenshot https://s3.amazonaws.com/diffy-files/2019/4/14/screenshot-1557852037-55032197.png
Another example of using such functionality is to submit forms or scrolling through the slider.
