Some use cases for visual regression testing

Updates or client break the site

Development

Compare your "before" and "after" screenshots to make sure that your code changes do not mess up your site's design or user interface.

Updates or client break the site

Customers Success Stories

Updates or client break the site

Diffy has a sort of multiplier effect that we can focus on the things that matter, where humans can do a better job of impacting and letting machines worry about this stuff that can be automated.

Capellic Case Study

Not only has Diffy allowed us to do the basics that should be done without having to have a human do it, but also it has given us the freedom to tackle tickets in a shorter time frame, less planning and allocation.

Shedule monitoring

Daily, weekly monitoring on your schedule

Monitoring will take screenshots and compare them with screenshots of previous run (i.e. yesterday) so you just receive an email notificaiton if anything found.

Adjust Page Content to avoid False Positives

Take care of ads, carousels, video embeds, popups so they never trigger false positives in your comparisons.

Better results with our Comparison Algorithm

If you’ve done visual regression testing before, you know that the tiniest vertical shifts due to browser rendering can lead to highlighting way bigger area than actually changed.

Our algorithm detects these shifts and provides much better results than pixel perfect comparison algorithms.

Create tickets for developers right from the tool

You can create ticket in your bug-tracking system (i.e. Jira, Asana, Trello, Basecamp etc.) right from Diffy with our Zapier integration
