chore(test): add e2e test for test-tabs-system-item-ios scenario by LKuchno · Pull Request #4147 · software-mansion/react-native-screens

LKuchno · 2026-06-10T13:22:05Z

Description

This PR implements the Detox e2e test suite for the test-tabs-system-item-ios scenario, covering the systemItem prop on iOS tab bar items.

The test covers: static system item rendering, runtime systemItem cycling (favorites/history/search), title override cycling (custom/hidden/system), icon override cycling (custom SFSymbols vs. system fallback), and combinations of all three overrides. All test blocks are wrapped in describeIfiOS since this feature is iOS-only. The scenario.md is updated to reflect what is and isn't automated.

⚠️ Notes

The following are explicitly not automated (documented in scenario.md):

Validating icon vs. selectedIcon differences
The search systemItem detached-state / label-hiding behaviour on iOS 26
"Hidden title" is verified indirectly only; manual verification recommended
Steps 20–23 (orientation changes)

Closes https://github.com/software-mansion/react-native-screens-labs/issues/1410

E2E/Tabs: Add test-tabs-system-item-ios.e2e.ts - new Detox test suite

I wonder if we should skip running this e2e completely if iOS < 26 is used but maybe it's not necessary.

Suggested change

it('should update the tab bar item label after tapping custom title', async () => {

it('should update the tab bar item label after switching to custom title', async () => {

nit: I think we should focus here on the result/intention of the action, not the literal action of tapping the button

applies to other places as well
