A macOs application that shows the failing snapshot tests fromFBSnapshotTestCase because it's a pain to parse the console logs by myself.

I've been using an amazingplugin to check the failing test's snapshots, but unfortunately, with Xcode 8 the plugins are not officially supported anymore, so I've decided to build an app which will work regardless Apple's decisions about Xcode and plugins ecosystem.

There are some benefits using it:

• Real-time feedback about failed snapshot test.
• Real-time feedback about recorded snapshot test.
• Clear output with reference | diff | failed image
• Split and diff mode to see exact differences
• One click to use failed image as a recorded
• Xcode and AppCode support

The idea behind the job is quite tricky, but the overall concept is straightforward:

1. The app listens for the changes in Xcode DerivedData folder;
2. When the app finds new .log file generated by Xcode it starts parsing it;
3. Through the parsing it extracts the generated information by iOS snapshot tests framework and shows in UI

At the moment there is only one option to install the app:Navigate toreleases and download the latestFBSnapshotsViewer-xyz.app.zip release.

We encourage you to turn automatic update on, so you'll be always up to date 🚀

As simple as just run the app and run tests in your app 🎉

For the AppCode support the app needs to know where is a folder with generated test logs:OpenFBSnapshotsViewer ->Right click ->Preferences -> Set derived data folder path as a path like~/Library/Caches/AppCodeXYZ whereXYZ is an AppCode version. Usually you'll have only one such folder under theCaches directory.
