Summary: This diff adds a custom matcher which will wrap a given component and shallow render it, snapshotting the result with the formatting users will see when they do the same. I also update the ActivityIndicator test to use this new strategy, and add an additional check that the displayName is set. For context see: - https://github.com/facebook/react-native/pull/21950 - https://github.com/rajivshah3/rn-broken-snapshot/blob/broken-example/__tests__/App.spec.js#L3 - https://github.com/facebook/react-native/issues/21937 Reviewed By: TheSavior Differential Revision: D13326689 fbshipit-source-id: 8ed2302a8aad12962fa2498a46d2502ccfb5c737
