Adds native to the list of jest-react-native platforms to fix testing with react-relay. Summary: See https://github.com/facebook/jest/pull/2170. Per cpojer's request, bringing this PR to react-native as well. **Summary** When using jest with React Native and Relay and recommended default settings, jest throws : ``` Cannot find module 'react-dom' from 'relayUnstableBatchedUpdates.js' at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:151:17) at Object.<anonymous> (node_modules/react-relay/lib/relayUnstableBatchedUpdates.js:15:18) at new RelayEnvironment (node_modules/react-relay/lib/RelayEnvironment.js:39:63) ``` Investigating this, I found out that https://github.com/facebook/jest/blob/master/packages/jest-react-native/jest-preset.json didn't have "native" in the list of platforms, hence jest can't pick up `relayUnstableBatchedUpdates.native.js` in react-relay. **Test plan** I copied and paste the content of https://github.com/facebook/jest/blob/master/packages/jest-react-native/jest-preset.json in my `package.json` `jest` section, as well a Closes https://github.com/facebook/react-native/pull/11179 Differential Revision: D4243073 Pulled By: cpojer fbshipit-source-id: bcfeb2235df4d466ba19d0a3fe94fc98835a20ea

Remove remnants of the packager Summary: There were still some references to "packager/" that are no longer used since the `packager` directory has been deleted after moving to Metro. Cleaned up the ones that were doing nothing and updated the references that are still meaningful.

Asset basenames in Jest snapshots Summary: This change only affects tests run with Jest. `require('/images/image1.png')` will be replaced with ``` Object { "testUri": "relative/path/to/images/image1.png", } ``` in the Jest snapshot instead of always being 1 returned by RelativeImageStub. This change makes it possible to test conditional asset loading in components. The problem with this change is that it will probably break a lot of existing snapshots, but that should be easily fixed when a project updates to a new version of React Native by running `jest -u` to update all snapshots. A component can have conditional asset loading based on its props, this logic would be nice to test with Jest snapshots. This problem has been discussed in https://github.com/facebook/jest/issues/2838. * **Who does this affect**: Everyone using `Image` in Jest snapshots * **How to migrate**: Running `jest -u` will update the snapshots, the snapshots should be reviewed that they are correct. * **Why make this breaking change**: It enables testing of conditional asset loading. * **Severity (number of people affected x effort)**: Low.
