[Jest] Make a disabled Pressable's testOnly_* handlers no-ops - #4669
In a test environment both v3 Pressable engines (PressableWithTouchable and StatefulPressable) forward the user's callbacks to the button as testOnly_onPress / testOnly_onPressIn / testOnly_onPressOut / testOnly_onLongPress / testOnly_onHoverIn / testOnly_onHoverOut. The press state machine runs natively, so that is how testing-library reaches them (context: #4417, #4416).
They are forwarded regardless of disabled, though. @testing-library/react-native (13.1 and later) looks up a press handler as onPress and falls back to testOnly_onPress (same for the other events). None of its enabled checks (pointerEvents, a non-editable TextInput, a responder declining in onStartShouldSetResponder) applies to the RNGH button, which only sets onStartShouldSetResponderCapture. So nothing marks the button as disabled, and fireEvent.press(), userEvent.press() and userEvent.longPress() on <Pressable disabled onPress={fn}> call fn in tests. On a device the button is rendered with enabled={false} and nothing fires.
That is a test-only false positive: a test asserting that a disabled Pressable can't be pressed fails, and a test can't catch a regression in the disabled state. We ran into it when bumping an app to 3.3.0 with RNTL 14: a test checking that a cancel button can't be pressed while a request is pending (disabled) started failing. Our workaround is mocking the v3 Pressable with React Native's Pressable in our Jest setup.
Repro (RNTL 14):
import{fireEvent,render,screen}from'@testing-library/react-native';import{Text}from'react-native';import{GestureHandlerRootView,Pressable,}from'react-native-gesture-handler';test('a disabled Pressable does not call onPress',async()=>{constonPress=jest.fn();awaitrender(<GestureHandlerRootView><PressabledisabledonPress={onPress}><Text>Cancel</Text></Pressable></GestureHandlerRootView>);awaitfireEvent.press(screen.getByText('Cancel'));expect(onPress).not.toHaveBeenCalled();// fails: called once});
Fix
In a test environment, both engines now swap each callback a disabled Pressable was given for a no-op in its testOnly_* prop, so testing-library stops at the button without running anything. Dropping the prop instead makes testing-library fall back to handlers further up the tree. For PressableWithTouchable those are the ones Touchable gets, so a bare fireEvent(button, 'pressIn') throws reading event.x, and a pressIn followed by press inside hitSlop still fires onPressIn and onPress (see the review thread). The hover callbacks are swapped too. Every platform masks hover on a disabled button (effectiveHover is isHovered && enabled on Android, iOS/macOS and web), and StatefulPressable's hover gesture is enabled: disabled !== true.
Callbacks that weren't given stay unset, as on an enabled button. Testing-library then keeps looking further up the tree for them, as it does on main, so pressing a disabled Pressable that has no onPress still reaches an enabled Pressable or Touchable around it. As on main, a bare fireEvent(button, 'pressIn') on a disabled Pressable without onPressIn still throws.
Nothing changes outside a test environment or for an enabled Pressable, so #4417 stays fixed. The handlers Touchable gets are left alone on purpose: the native button still reports press-out and hover-out when it gets disabled mid-press or mid-hover, and Pressable needs them to reset pressed and call onPressOut / onHoverOut.
LegacyPressable has the same wiring, but jestSetup.js replaces it with React Native's Pressable, which honours disabled, so I left it alone. #3612 fixed the same kind of bug for the legacy buttons' enabled prop.
Test plan
Added a regression test to src/__tests__/mocks.test.tsx that runs on both engines. It calls each testOnly_* handler of a disabled Pressable without an event, the way a bare fireEvent(button, 'pressIn') does, and checks that nothing throws and none of the callbacks fire. It also checks that a disabled Pressable without callbacks leaves the testOnly_* props unset. It fails on main, where the user's callbacks fire, and passes with this change. Like Forward press handlers as testOnly_* in PressableWithTouchable #4416, it checks the props instead of calling fireEvent, because this repo pins @testing-library/react-native@12.9, and that version doesn't look up testOnly_* props.
Ran a throwaway suite (not committed) against @testing-library/react-native 13.3.3 and 14.1.0 on both engines, mapped in through a scratch Jest config. For a disabled Pressable given all six callbacks, it covers bare fireEvent calls with press, pressIn, pressOut, longPress and hoverOut, a pressIn followed by press with an event (with and without hitSlop), hoverIn with an event, fireEvent.press on the button and on a child Text, userEvent.press and userEvent.longPress:
On main, every one of them fires the matching callbacks.
With this change none of them fires anything or throws.
On an enabled Pressable, fireEvent.press and userEvent.press still fire the callbacks.
On PressableWithTouchable, native buttonPressOut / buttonHoverOut events dispatched after it gets disabled mid-press / mid-hover still call onPressOut / onHoverOut and reset pressed.
Ran a second throwaway suite on 12.9, 13.3.3 and 14.1.0 with a disabled Pressable (both engines) inside an enabled Pressable or Touchable. It covers fireEvent.press on the inner button and on its Text, a bare fireEvent(button, 'pressIn'), and userEvent.press:
With callbacks of its own, nothing fires on 13.3.3 and 14.1.0. On main the inner callbacks fire.
Without callbacks, every case behaves as on main, including the enclosing onPress firing where it did before.
On 12.9 every case behaves as on main.
In packages/react-native-gesture-handler:
yarn test: 26 suites, 258 tests pass.
yarn ts-check: clean.
yarn lint:js: 0 errors and no warnings in the touched files. The Prettier check is clean.
In test environments, disabled pressables now expose callable test-only press and hover handlers that safely do nothing when invoked without an event, without triggering their callbacks. This applies to both pressable engines. Enabled pressables retain their configured handlers, unset callbacks remain unset, and production behavior is unchanged.
Both Pressable engines now provide no-op test-only event handlers when disabled in test environments. A parameterized test checks these handlers for both engines and verifies that unset callbacks produce unset handler props.
Both engines route test-only event props through a helper. In test environments, the helper returns a no-op for a supplied handler when disabled. It preserves supplied handlers when enabled and unset handlers when no callback is supplied. Outside test environments, it returns undefined.
Test disabled Pressables packages/react-native-gesture-handler/src/__tests__/mocks.test.tsx
A parameterized test checks that supplied callbacks have callable test-only handlers that do not throw when invoked without an event and are not called. It also checks that handler props are unset when callbacks are removed.

In a test environment both v3 `Pressable` engines forward their callbacks to the button as `testOnly_*` props, which testing-library (>= 13) calls from `fireEvent`/`userEvent`. They were forwarded regardless of `disabled`, so pressing a disabled `Pressable` in a test called `onPress` even though the disabled native button never fires it on a device. Withhold the `testOnly_*` handlers while `disabled`.

Withholding the `testOnly_*` handlers of a disabled `Pressable` let testing-library (13.1+) fall back to handlers further up the tree. For `PressableWithTouchable` those are the ones `Touchable` gets: a bare `fireEvent(button, 'pressIn')` threw reading `event.x`, and a `pressIn` followed by `press` within `hitSlop` still fired `onPressIn` and `onPress`.
Give a disabled button no-op `testOnly_*` handlers instead, so testing-library stops at the button. The handlers `Touchable` gets stay as they are, since the native button still reports press-out and hover-out when it gets disabled mid-interaction.

…o-ops
Giving a disabled button a no-op for every `testOnly_*` prop also made testing-library (13.1+) stop at the button for events the `Pressable` has no callback for. A press on a disabled `Pressable` without `onPress` then no longer reached an enabled `Pressable` or `Touchable` around it, as it does on main and for an enabled button.
Swap only the callbacks that were given. The rest stay unset, so the lookup continues as it does on main.
@coderabbitai Re the nitpick on mocks.test.tsx (L224-268): I checked it and skipped both parts.
fireEvent test with an ancestor callback: skipped. On the pinned RNTL 12.9 it would add no coverage:
12.9's fireEvent never reads testOnly_*, so it can't reach the no-ops this PR adds.
If the disabled Pressable has its own onPress, Touchable's handlePress stops the lookup and does nothing. The test would pass on main too.
If it has no onPress, 12.9 reaches the onPress of an enabled Touchable around it, on main and with this PR alike.
"Neither callback runs" isn't the right expectation for that second case either: reaching the enclosing callback is how it already works on main, and for an enabled button.
Checking this showed that 5256449 changed that on 13.1+. Making every testOnly_* prop a no-op stopped the lookup at the disabled button even for events it has no callback for. ef9a749 swaps only the callbacks the Pressable was given, and leaves the rest unset. The regression test now also checks that (at the prop level, so it runs on 12.9), and that part fails on 5256449.
I verified it locally with a scratch Jest config, not committed: 12.9, 13.3.3 and 14.1.0, both engines, a disabled Pressable inside an enabled Pressable or Touchable.
With callbacks of its own, nothing fires on 13.3.3 and 14.1.0. On main the inner callbacks fire.
Without callbacks, everything behaves as on main, including the enclosing onPress.
On 12.9 everything behaves as on main.
RNTL 13.1+ test config / CI job: not added. It needs a second testing-library (plus test-renderer for 14) in the dev dependencies and a CI job. That is a repo-level call, so I'm leaving it to the maintainers as a follow-up. My local runs on 13.3.3 and 14.1.0 are listed in the PR description.

Keep Touchable's internal handlers out of RNTL's ancestor lookup.
When a disabled PressableWithTouchable has no onPressIn callback, RNTL 13.1+ finds Touchable's internal onPressIn. A bare fireEvent(button, 'pressIn') then invokes it without an event and throws in buttonToInner(event).
Do not make every absent callback a no-op in testOnlyHandler, because that blocks intended lookup of handlers on outer ancestors. Give PressableWithTouchable a private callback path into Touchable so the internal callbacks are not exposed as test-tree on* props. Keep the native onButtonPressIn and onButtonHoverOut wiring unchanged.

@maykonmichel Thanks for the detailed checks. I withdraw both nitpicks.
The current mocks.test.tsx test covers both engines. It checks that supplied callbacks become callable no-ops and that absent callbacks remain undefined. Both implementations match those assertions.
Given your RNTL 12.9 findings, the proposed fireEvent test would not exercise the changed testOnly_* path. My “neither callback runs” expectation was also incorrect when the inner Pressable has no callback for that event.
A committed RNTL 13.1+ configuration can remain a maintainer follow-up. I inspected the source but did not rerun your version matrix.
Would you like me to open a follow-up issue for that test configuration?
