Samuel Susla 65ffc588fb introduce convenience method Fantom.scrollTo (#50011)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50011

changelog: [internal]

Majority of time, you want to simply scroll. This diff introduces a convenience method Fantom.scrollTo.

Previously, you would have to write:
```
  Fantom.runOnUIThread(() => {
    Fantom.enqueueScrollEvent(element, {
      x: 0,
      y: 60,
    });
  });
  Fantom.runWorkLoop();
```

Now, you can just do:
```
 Fantom.scrollTo(element, {
    x: 0,
    y: 60,
  });
```

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49912

Changelog: [internal]

This migrates all Fantom tests to use package-relative imports from `react-native` instead of relative paths.

Note that a lot of the current deep imports (e.g.: `import ReactNativeElement from 'react-native/src/private/webapis/dom/nodes/ReactNativeElement'`) will not be necessary when we release those APIs as public.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49691

Changelog: [internal]

This adds a new getter for `document` in the `Root` class in Fantom tests to easily access the document instance for the root.

This isn't very useful at the moment, but will be very useful when we introduce `document.getElementById`, so we can access arbitrary nodes very easily.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49251

Changelog: [internal]

Components like `AppContainer` require passing the rootTag as a prop, but we don't have access to it from Fantom unless we render something in the root and access it via the RootTagContext. This exposes the rootTag of the Root as a method so we can use it in initial render too.

Rubén Norte 9a1dadf799 Introduce Fantom.dispatchNativeEvent utility (#49254)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49254

Changelog: [internal]

This is just a convenience method to do:

```
Fantom.dispatchNativeEvent(node, 'click');
```

Instead of:

```
runOnUIThread(() => {
  enqueueNativeEvent(node, 'click');
});

runWorkLoop();
```

Which is too verbose and people rarely need this level of granularity in tests.

Note that, in Fabric, we have methods called `dispatchEvent` that don't match 1:1 with this API. In that case, `dispatchEvent` is more aligned with Fantom's `enqueueNativeEvent`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49253

Changelog: [internal]

Renaming this low level method as `enqueue` is more accurate in this case than `dispatch`, which is misleading because it actually doesn't dispatch it to JS.

We should also rename this in Fabric, but that's a larger and breaking change, so just making the change in Fantom for now. This is a trade-off between convenience/ergonomics of the testing API vs. alignment with the internal nomenclature. In this case we favor the first.

Rubén Norte d2a6ff0c37 Add method to take a save a JS memory heap snapshot (#49125)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49125

Changelog: [internal]

This adds support for taking JS memory heap snapshots from Fantom tests via `Fantom.saveJSMemoryHeapSnapshot`. This can be used in one-off tests to do memory analysis and determine the existence of leaks:

```
// Warm up

Fantom.saveJSMemoryHeapSnapshot('/path/to/my/1.heapsnapshot');

// Do work

Fantom.saveJSMemoryHeapSnapshot('/path/to/my/2.heapsnapshot');

// Clean up

Fantom.saveJSMemoryHeapSnapshot('/path/to/my/3.heapsnapshot');
```

Load these snapshots in Chrome and select "Objects allocated between 1 and 2" in the dropdown to see the potentially leaked objects.

In the future we could introduce additional utilities to analyze the snapshots and do the detection automatically, e.g.:

```
// Warm up

const baseline = Fantom.takeJSMemoryHeapSnapshot();

// Do work

const before = Fantom.takeJSMemoryHeapSnapshot();

// Clean up

const after = Fantom.takeJSMemoryHeapSnapshot();

const leaks = findMemoryLeaks(baseline, before, after);
expect(leaks.sizeKB()).toBeLessThan(THRESHOLD);
```

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49009

Changelog: [internal]

Native APIs so far have returned instance handles from React to reference nodes in the rendered UI tree, but now that we're adding support for the document API, this isn't sufficient to represent all types of nodes. Both for the document and for its `documentElement`, we don't have an instance handle from React that links to the node, but we're going to represent that differently.

This is a refactor so the existing methods use a mostly opaque `NativeNodeReference` type so we can implement it as a union of React instance handles and the future types we're going to introduce to support document.

Moves the internals to access instance handle and shadow node from public instances from `ReadOnlyNode` to `NodeInternals` so it's more obvious when people are reaching into internal APIs/state.

Rubén Norte ff7c550a86 Run benchmarks in test mode when not specifying verification functions in CI (#48451)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48451

Changelog: [internal]

Modifies the execution of benchmarks in CI to run benchmarks in test mode when they don't define a `verify` method.

If a benchmark uses `verify`, the test is meant to make sure that the benchmark doesn't regress in CI. If it doesn't, then running the benchmark on CI doesn't provide much value. In that case, we run a single iteration of each test case just to make sure things don't break over time.

Rubén Norte 3795f0fb66 Add API to run benchmarks in Fantom (#48452)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48452

Changelog: [internal]

Implements a basic API to run benchmarks with Fantom (using `tinybench` under the hood):

```
import {benchmark} from 'react-native/fantom';

benchmark
  .suite('Suite name', {
    // options
  })
  .add(
    'Test name',
    () => {
      // code to benchmark
    },
    {
      beforeAll: () => {},
      beforeEach: () => {},
      afterEach: () => {},
      afterAll: () => {},
    },
  )
  .verify(results => {
    // check results and throw an error if the expectations fail
  });
```

Features:
* Print benchmark results in the console as a table.
* It opts into optimized builds automatically
* Verifies that optimized build is used (unless manually opting out of the check via `disableOptimizedBuildCheck`).
* Supports verification of results (making expectations and making the test fail if the benchmark doesn't meet some expectations).
