Changelog

2.3.0

• Diff and Failure images are now automatically deleted when re-recording snapshots, rather than just when a test passes.
• Failure HTML file only gets generated when at least one test fails due to snapshot test failures, rather than any failure.
• PixelTest now caches generated images during tests.
• Removed static property for choosing the failure HTML file name, since it’s mostly pointless unless you’re using a principle class to set it. If this is an issue for you, please let me know and I can re-add it, but I'm fairly confident this doesn't affect anyone.
• PixelTest now declares it uses Swift 5, although there was no source changes needed for this it was annoying to have the migration warning in Xcode which will disappear if you update to 2.3.0.

2.2.0

• Added conveniences for calling verify with a UIViewController, UITableViewCell or UICollectionViewCell directly without having to pass in the view or contentView manually.
• Added convenience .dynamicHeight LayoutStyle you can use in your tests which automatically resolves to .dynamicHeight(fixedWidth: 320) since that's the most common: verify(view, layoutStyle: .dynamicHeight)
• Added a way to override the mode globally, either per-Xcode scheme (which re-records every test in every test target), or per-test target (which re-records every test in the target).
  • In the Xcode scheme you add an environment variable called PTRecordAll with a value of YES.
  • In the individual test targets you add a new Boolean entry into its Info.plist called PTRecordAll with a value of YES.
• Added a way to generate placeholder images of any size using UIImage.sized(width: 250, height: 100). Images are generated in code and aren't stored as assets, so PixelTest will be able to support Swift Package Manager still in the future.
• Tests will now automatically fail if you forget to add at least one call to verify in your test function.
• Small improvements to the failure message when a test fails because the images are different.
• Fixed a rogue apostrophe in the generated failure HTML code which caused the layout to break a bit.
• Hides and shows the red split indicator on the generated failure HTML when you hover over the overlaid split images (so that it doesn't obscure the content).
• Added a conventional "checkerboard" background to transparent images in the generate failure HTML.
• Generated failure HTML file now indicates how many failures there are in the tab title.

2.1.0

• Added public extension on String for generating short/medium/long content when populating view models for snapshots. See README for me information.

2.0.0

• Removed requirement for the PIXELTEST_BASE_DIR environment variable.
  • Snapshots are now stored in a directory relative to the test file, but this means a breaking change for existing PixelTest users.
• Removed dependency on xcproj, meaning PixelTest has no dependencies now!
