No more repetitive manual cross-browser testing

Do you want to get on with other stuff instead?

Automated Responsive Design Testing book cover

Testing your websites across all the popular browsers and devices is tedious, slow and often expensive. There are 100 more useful things that you could be doing.

But testing is important.

Manual testing is getter harder

  • You are committed to high quality web designs that work across all the major browsers
  • You use the latest responsive design techniques to provide a great experience for users of different devices
  • You wish there was a better way to test that your designs work on popular devices and browsers

How often have you manually tested your design only to find that your approach simply doesn't work on one of the major browsers?

Sometimes this means having to change tack completely, or putting browser-specific hacks in place to work around the problem.

Manually testing on a wide range of devices and browsers takes a lot of time, expense and anguish.

Wouldn't it be great to delegate away most of this tedium and overhead so you can focus on those 100 other more important things?


With some upfront time investment, automating your cross-browser layout testing can pay off handsomely over the course of a project.

There are now tools that can test your layouts in a wide range of browsers and devices for you.

Automated testing tools can:

  • be set up to run tests on demand, or automatically when code changes
  • test responsive designs, so that you can set different expectations at different screen dimensions
  • run all these tests in the cloud so you don't need to run your own expensive device laboratory


By automating such a big chunk of work, you may see some of these benefits:

  • Save many, many hours over the course of your project
  • Reduce the amount of time you spend maintaining test browsers and devices
  • Colleagues, clients or managers will think you are a magician
  • You and your team will be more motivated to fix bugs
  • Your design process can change for the better, by embracing testing earlier
  • Take an incremental approach to quality

This visual step-by-step guide will help you to set up an automated testing system, write your own test specs, and start changing how you work for the better.

Robbie Manson

Jim not only guides you step-by-step through getting started with automated testing, but perfectly outlines why it’s so valuable, and how to use it responsibly.

Orde Saunders

Testing is the foundation of maintainable code but with responsive websites the number of permutations can make testing seem impractical.

“In Automated Responsive Design Testing you’ll find pragmatic advice that will allow you to build and grow websites with confidence.

Daniel Furze

Automated Responsive Design Testing is an extremely clear, well-written book both for those with no experience of testing and for veterans on the subject.

“It helped me convince my team of the benefits of integrating testing into our workflow and we've not looked back since.
