Duplicated testID on RectButton (iOS and Fabric only) #3698

Description

We are using Detox to run e2e test on our application. We noticed that after upgrading to version 2.25.0 (applies for all versions up to 2.28.0 which is current at time of writing) the by.id test matcher (docs) does no longer work for RectButtons on iOS.

While debugging the issue I noticed that the testID is applied in two places in the view hierarchy. The Component View and the actual UIControl:

Here's an excerpt of the view hierarchy of such a failing test. Notice how id="sign-in-button" appears twice:

<RNGestureHandlerButtonComponentView class="RNGestureHandlerButtonComponentView" id="sign-in-button" label="Get started">
    <RNGestureHandlerButton class="RNGestureHandlerButton" id="sign-in-button" label="Get started">
        <RCTViewComponentView class="RCTViewComponentView" />
        <RCTParagraphComponentView class="RCTParagraphComponentView" label="Get started" text="Get started">
            <RCTParagraphTextView class="RCTParagraphTextView" />
        </RCTParagraphComponentView>
    </RNGestureHandlerButton>
</RNGestureHandlerButtonComponentView>

This causes Detox to fail, when looking for the object:

Test Failed: Multiple elements found for "MATCHER(id == "sign-in-button")"

I believe this might have been introduced in PR #3444 (appeared first in version 2.25.0).

Steps to reproduce

I've created a repository with a minimal reproduction scenario: https://github.com/stigi/gesture-handler-testid-bug

  • git clone https://github.com/stigi/gesture-handler-testid-bug.git
  • cd gesture-handler-testid-bug; npm i
  • npm run detox:build:ios
  • npm run detox:test:ios -- --loglevel verbose (in a 2nd terminal)

Depending on your local setup you might have to adjust which simulator Detox chooses to test with here.

A link to a Gist, an Expo Snack or a link to a repository based on this template that reproduces the bug.
