 By default, AccessibilitySnapshot uses [SnapshotTesting](https://github.com/pointfreeco/swift-snapshot-testing) to record snapshots and perform comparisons. The framework also includes support for using [iOSSnapshotTestCase](https://github.com/uber/ios-snapshot-test-case) as the snapshotting engine instead. Before setting up accessibility snapshot tests, make sure your project is set up for standard snapshot testing. Accessibility snapshot tests require that the test target has a host application. See the [Extensions](#extensions) section below for a list of other available snapshotting options.
