Visual regression testing on patterns

  1. Good working knowledge of atomic design principles.

Session details

In this session we will go over using BackstopJS for visual regression testing on Pattern Lab patterns on a Drupal 8 theme. We will not go over integration of Drupal and Pattern Lab, it is assumed that the attendee will already have working knowledge of how the integration works. We will go over how to setup regression testing for each pattern and for the entire pattern library. We will talk about the problems you could run into when setting up regression testing for patterns and the benefits of using this approach.

Drupal apprentices

The best people to train new developers are developers

The Drupal Apprenticeship Scheme will be running a London intake in March. If you are interested in hiring an apprentice or know someone who would benefit from the scheme please get in touch via the link below.

  • Created and run by experienced developers
  • Teaches core skills and best practice
  • Extensive support for businesses and teams

We are also really keen to hear from people who might be interested in mentoring, training and helping us to develop and review training materials to make sure they stay absolutely current and relevant.
