Image Snapshot Testing with Mocha
I started to fiddle around with jest-image-snapshot in combination with expect-mocha-snapshot, and it turned out to be way easier than expected to make it Mocha compatible. I put it into its own NPM package, called expect-mocha-image-snapshot. Usage is pretty similar to Jest, you only have to pass the testing context via this. Here is a quick code sample:

Image Snapshot Testing with Mocha
Snapshot testing itself is a built-in feature of Jest, and when searching specifically for image snapshots, you'll quickly find jest-image-snapshot, which does great work comparing and updating image snapshots. It also provides convenience features like a base64 diff output, which allows us to view the diff from a CI environment (since the diff image file cannot be saved or viewed).
