Testing tabs, mobile menu, sliders

A lot of web pages right now have some elements that get activated by clicking on the pages. For example, sliders, or dropdown menus, or tabs. How to take screenshots of those pages too?

 

Here is an example of how you can do that with Diffy.

 

Let's take an example of the site https://ec.europa.eu/info/index_eu. We would like to take screenshots of not only the homepage but also the language switcher and the second slide on the homepage slideshow.

 

For that we can create three URLs from the homepage:

https://ec.europa.eu/info/index_en
https://ec.europa.eu/info/index_en#language-switcher
https://ec.europa.eu/info/index_en#next-slide

 

And now we can add custom javascript (under Project Settings > Advanced > Custom Javascript) that gets injected into the pages to trigger actions based on the URL like:

if (window.location.hash == '#language-switcher') {
  // trigger the language switcher.
}

if (window.location.hash == '#next-slide') {
  // trigger the slider to move it one the next one.
}

 

This will make three screenshots of the homepage but with different actions run. So we get all the elements covered.

Make some pages for Visual Regression Testing only in Drupal

When you do visual regression testing, it can be a great idea to have some dedicated pages with all the different elements of your site combined. So instead of running screenshots of many pages on your site, you could do just a few and cover all the UI. These are also sometimes called style guides.

On the other hand, you do not want your site visitors to accidentally open these pages and be surprised by what they are for.
