This flag allows us to run optimized mode by using the right buck modes for the Fantom CLI, using minified + dev in Metro and building bytecode using Buck as well.
It's disabled by default but in the future we can enable it based on the configuration in the test file (e.g.: if it's a benchmark) or we can run tests in both modes by default to catch problems caused by the differences between environments.

Pull Request resolved: https://github.com/facebook/react-native/pull/47646
changelog: [internal]
In order to control scheduling of tests, test setup must be separated from test running. This is because of how internal scheduling of React Native is restricted until bundle is loaded via BufferedRuntimeExecutor. This is the reason for executing tests by calling global function `$$RunTests$$`. This is not a pretty solution but it is hidden within testing infrastructure and users of our test infra are not exposed to this.
There is a new method exposed to JavaScript: flushMessageQueue. This will flush everything that is inside of message queue. This is the queue where tasks are queued whenever RuntimeScheduler enqueues something by calling `runtimeExecutor_`.

Pull Request resolved: https://github.com/facebook/react-native/pull/42690
Issues triggered by `InspectorProxy*` tests under `packages/dev-middleware` (T169943794) can be root-caused to `dev-middleware` performing Babel registration within a test run, after Jest has hooked its own transformer.
Babel registration is only required when running this code (`dev-middleware`, etc) directly from source - we already have the `BUILD_EXCLUDE_BABEL_REGISTER` mechanism to strip it out from production builds, but we currently don't prevent registration under tests, where Jest's transformer should be allowed to do its work.
This adds the same `babel-plugin-transform-define` mechanism that we use for production builds to the Jest transformer.

As `react-native/babel-preset` is extended to include parts of codegen (written in Flow) via `react-native/babel-plugin-codegen`, we need to register Babel (with a Node JS config) in order to load the `react-native/babel-transformer` that Jest needs to transform RN code when running from source.

Now that `metro-react-native-babel-transformer` may be loaded from source without transformation, we can remove this workaround / potential footgun.
Jest uses Babel imperatively and doesn't rely on registration (require hooks), so registering within the preprocessor potentially conflicts and has caused problems before. This just tidies up some complexity we don't need.

Changelog:
[General][Changed] - The default `metro.config.js` in apps now extends `react-native/metro-config`, and should be updated in existing apps.
~~`react-native/rn-get-polyfills.js` is removed and should be updated to `react-native/js-polyfills` in existing apps (this is part of the new default config).~~
#publish-packages-to-npm
## Context
### React Native Metro config → React Native repo (https://github.com/facebook/react-native/pull/36502)
We (the React Native team) are aiming to relocate the default Metro config for React Native out of `react-native-community/cli-plugin-metro` and **into the React Native repo + app template** as a new `react-native/metro-config` package.
This is the first (and minimum viable) phase we can ship to separate the release process of Metro from RN CLI in order to reduce coupling and iterate faster for our users.
**See full motivation, design, and test plan (which previewed the CLI bump) here: https://github.com/facebook/react-native/pull/36502**
## Changes
NOTE: This PR is pending the inclusion of a bump to `react-native-community/cli`, and will be sequenced after https://github.com/react-native-community/cli/pull/1875 is merged.
- Upgrade `react-native-community/cli` to `11.0.0`, upgrade all `metro` packages to `0.76.0` (version distributed in this CLI release).
- Update the `metro.config.js` file in `packages/react-native/template/`.
- Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0.
- Update the `metro.config.js` files for `packages/react-native/` and `packages/rn-tester/` (these are integration test locations).
- Now merges defaults from `react-native/metro-config`, and can be used with CLI >= 11.0.0.
Changes to `react-native/metro-config` — `0.72.1` (prepared but not depended on yet):
- Export `mergeConfig` util (removing direct `metro-config` dependency in consuming projects).
- Explicitly depend on `metro-react-native-babel-transformer` and `metro-runtime` (transitively included today).

Pull Request resolved: https://github.com/facebook/react-native/pull/36523
`jest/private/preprocessor.js` is only used to run tests on the workspace itself, it's not part of our exported Jest preset and is specifically excluded from publication in the `react-native` package.
Now that we have the monorepo setup, this belongs at the workspace root.
- `metro-react-native-babel-transformer` moved from RN `dependencies` to root `devDependencies` because it's only used by the preprocessor
- `jest/create-cache-key-function` added to `devDependencies` - it's also used by the `assetTransformer` in the public preset.

Summary:

Also includes a subtle update to how this is accomplished. Instead of overriding `exportConditions()`, we assign to the underlying class property — this allows users (once https://github.com/facebook/jest/pull/13989 is merged) to override `customExportConditions` via [`testEnvironmentOptions`](https://jestjs.io/docs/configuration#testenvironmentoptions-object).

Summary:
This change aligns requestAnimationFrame implementation used in Jest environment with web standard, and with the implementation that runs in the application environment.
As per specification https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame#parameters – requestAnimationFrame callback gets a single parameter, which represents the current frame timestamp. The current polyfill maps requestAnimationFrame directly to setTimeout which makes the callback execute without any parameters.
## Changelog
[General] [Fixed] - Jest mocked requestAnimationFrame callbacks now receive a timestamp parameter
Pull Request resolved: https://github.com/facebook/react-native/pull/35919
Test Plan:
1. execute jest test suite to make sure nothing breaks
2. add the below code to one of the tests:
```
jest.useFakeTimers();
requestAnimationFrame((timestamp) => console.log("rAF", timestamp));
jest.runOnlyPendingTimers();
jest.useRealTimers();
```
this code will print `undefined` before and numer `0` representing the mocked frame time after this change.

Summary:
This PR is the follow up to the conversation started here by SimenB: https://github.com/react-native-community/discussions-and-proposals/issues/509
Basically, we want to move RN to use its own custom environment so that we can tweak it going forward - this PR in fact only sets up the groundwork for that; robhogan mentioned that with this in place, Meta engineers can
> iterate on it (with jest-environment-node as a starting point) against our internal product tests
This is also connected to Rob's work to bring Jest 29 into the codebase https://github.com/facebook/react-native/pull/34724 and my "mirror" PR to bring template in main up to the same version (https://github.com/facebook/react-native/pull/34972)
