Summary:

Adds Fantom -itest.js coverage for maintained, public React Native APIs that were previously untested or thinly tested, driving both the JavaScript logic and the underlying cross-platform C++ through the public react-native package surface.

New test files:

  • Animated/__tests__/SpringAnimation-itest.js, DecayAnimation-itest.js, AnimatedColor-itest.js, AnimatedComposition-itest.js — spring/decay animations (JS and native driver), Animated.Color value semantics, and the composition nodes (add/subtract/multiply/divide/modulo/diffClamp/tracking).
  • Components/View/__tests__/View-nativeCSSParsing-itest.js — string-valued CSS (color functions, transform, gradients) parsed via native CSS parsing.
  • Pressability/__tests__/Pressability-touch-itest.js — press in/out/press, long press, press delay, and responder termination via touch events and the deterministic timer mock.
  • Interaction/__tests__/PanResponder-itest.js — grant/move/release/terminate and gesture state across touch sequences.
  • LayoutAnimation/__tests__/LayoutAnimation-itest.jsconfigureNext/create/presets applying the resulting layout.
  • Network/__tests__/Network-itest.js — synchronous XMLHttpRequest lifecycle and validation.

Extended test files:

  • Components/TextInput/__tests__/TextInput-itest.jsonSelectionChange/onSubmitEditing/onKeyPress/onEndEditing events.
  • Lists/__tests__/FlatList-itest.jsonViewableItemsChanged via viewabilityConfig and viewabilityConfigCallbackPairs.
  • Text/__tests__/Text-itest.jsletterSpacing, lineHeight, and fontVariant styles.

The JS-driver decay test asserts that the animation completes (which exercises onUpdate) rather than asserting per-frame movement, since the requestAnimationFrame-based decay does not expose stable intermediate frame values under the test runner's virtual clock.

This is a test-only change with no runtime or user-facing impact.

Summary:

Adds Fantom `-itest.js` coverage for maintained, public React Native APIs that were previously untested or thinly tested, driving both the JavaScript logic and the underlying cross-platform C++ through the public `react-native` package surface.

New test files:
- `Animated/__tests__/SpringAnimation-itest.js`, `DecayAnimation-itest.js`, `AnimatedColor-itest.js`, `AnimatedComposition-itest.js` — spring/decay animations (JS and native driver), `Animated.Color` value semantics, and the composition nodes (`add`/`subtract`/`multiply`/`divide`/`modulo`/`diffClamp`/tracking).
- `Components/View/__tests__/View-nativeCSSParsing-itest.js` — string-valued CSS (color functions, transform, gradients) parsed via native CSS parsing.
- `Pressability/__tests__/Pressability-touch-itest.js` — press in/out/press, long press, press delay, and responder termination via touch events and the deterministic timer mock.
- `Interaction/__tests__/PanResponder-itest.js` — grant/move/release/terminate and gesture state across touch sequences.
- `LayoutAnimation/__tests__/LayoutAnimation-itest.js` — `configureNext`/`create`/presets applying the resulting layout.
- `Network/__tests__/Network-itest.js` — synchronous `XMLHttpRequest` lifecycle and validation.

Extended test files:
- `Components/TextInput/__tests__/TextInput-itest.js` — `onSelectionChange`/`onSubmitEditing`/`onKeyPress`/`onEndEditing` events.
- `Lists/__tests__/FlatList-itest.js` — `onViewableItemsChanged` via `viewabilityConfig` and `viewabilityConfigCallbackPairs`.
- `Text/__tests__/Text-itest.js` — `letterSpacing`, `lineHeight`, and `fontVariant` styles.

The JS-driver decay test asserts that the animation completes (which exercises `onUpdate`) rather than asserting per-frame movement, since the `requestAnimationFrame`-based decay does not expose stable intermediate frame values under the test runner's virtual clock.

This is a test-only change with no runtime or user-facing impact.
