Sorting screenshot changes for easier reviews

Occasionally, you have to update Xcode in your project, or perhaps you need to upgrade a low level library, or your snapshot testing library.

Usually these updates result in many minor snapshot changes. Developers tend to skim through these changes, since it might be hard to review 1000s of such changes manually.

But what if there’s an actual change there that needs reviewing? In particular, Xcode upgrades might come with its own regressions.

To make this easier to review, we now have a way of sorting your screenshots by how much the screenshot changed. Screenshots with large changes will be at the top of the report, which makes it easier to find the real regressions.

You can try out this feature from any report using More->Sorted by changes:

Since this feature is new, we would love to hear your feedback. Let us know if metric we’ve chosen to compute the difference doesn’t work well enough for you.
