+# Test Scenario: Dismiss Events
+
+## Details
+
+**Description:** Verify that the `FormSheet` component correctly emits dismiss events. The `onDismiss` event should be fired every time the sheet is dismissed programmatically. The `onNativeDismiss` event should be fired when the user dismisses the sheet via a native gesture (e.g., swiping down or tapping the backdrop).
+
+**OS test creation version:** iOS: 18.6 and 26.4
+
+## E2E test
+
+TBD: Planned, but will be implemented separately.
+
+## Prerequisites
+
+- iOS device or simulator: iPhone
+
+## Steps
+
+### Baseline
+
+1. Launch the app and navigate to the **Dismiss Events** screen.
+
+- [ ] An example with "Open FormSheet" and "Clear Logs" buttons is shown, along with an empty event logs area.
+
+---
+
+### Native Dismissal (Swiping down)
+
+2. Tap the "Open FormSheet" button.
+3. Wait for the sheet presentation animation to finish.
+4. Dismiss the FormSheet by swiping it down to the bottom of the screen.
+
+- [ ] The FormSheet dismisses smoothly and returns the user to the underlying main screen.
+- [ ] The logs list updates to show new `onNativeDismiss` event added.
+
+---
+
+### Programmatic Dismissal (JS)
+
+5. Tap "Clear Logs" to reset the list.
+6. Tap the "Open FormSheet" button.
+7. Wait for the sheet presentation animation to finish.
+8. Tap the "Dismiss from JS" button inside the FormSheet.
+
+- [ ] The FormSheet dismisses smoothly and returns the user to the underlying main screen.
+- [ ] The logs list updates to show new `onDismiss` event added.
