Inline snapshots and more strategies

What's new

• @rjchatfield has introduced (#199) a brand new way of snapshotting textual information, called "inline snapshot testing," which automatically inlines snapshots directly in your test file. The 1.5.0 release includes a preview of this functionality! You can use the _assertInlineSnapshot helper to try it out. Thanks to @rjchatfield for the PR, and find out more here.

  

• Two new URLRequest snapshot strategies have been included. First, @Sherlouk has included a curl snapshotting strategy (#203), which snapshots your prepared requests in the cURL format. Also we now have a snapshot strategy for capturing a URLRequest with its body pretty printed, when possible (#157). This helps make POST requests more easily inspectable in the reference file.

Swift 5 Support

This release brings SnapshotTesting up to date with Swift 5!

What's changed?

• Swift 5 support!
• The SnapshotTestCase subclass is no longer needed on Linux and has been deprecated as a type alias to XCTestCase. The type alias will be removed in a future version (#200).
• The dump strategy has been optimized (#195).

11" iPad Pro Support, Better Extensibility, Better Messaging

What's new?

• A new view configuration for the 11" iPad Pro's resolution and safe area (#187).
• A few let properties on Snapshotting and Diffing have been relaxed to be vars to make it easier to build strategies from existing ones (#189).
• The UIImage diff message has been generalized to read nicely while in record mode (#188).

1.2.0

What's new?

• Small updates to failure messages #153
• Renamed generics in pullback #154
• Support asserting against multiple strategies at once #150
• Make XCTAttachment's initializers public #159

1.1.0

What's new?

• Updated UIView and UIViewController recursiveDescription strategies to support custom trait collections and configuration (#141)
• Added a new UIViewController hierarchy snapshot strategy (#139)
• Added a new func strategy on functions that take CaseIterable values (#94)
• Added a new description strategy powered by String.init(describing:) (#94)

What's been fixed?

• Improved the assertSnapshot function's generic names (#120)
• Improved the recording failure message (#135, #140)
