+# Test Scenario: tabBarControllerMode
+
+**E2E:** Not automated - test will be added at least for iPad to check sidebar visibility.
+
+## Prerequisites
+
+- iPhone simulator or device
+- iPad simulator or device (required for `tabSidebar` mode)
+- iOS 18+
+
+## Steps
+
+### iPad
+
+1. Launch the app and navigate to the **Tab Bar Controller Mode** screen.
+
+- [ ] Expected: Tab bar displayed at the top with Tab1 and Tab2. Picker defaults to `automatic`
+
+2. Ensure that tabBarControllerMode = `automatic`
+
+- [ ] Expected: Tab bar displayed according to iPadOS default behavior for current orientation
+
+3. Change app window size to correspond to iPhone view.
+
+- [ ] Expected: Tab bar displayed at the **bottom**
+
+4. Resize app to full screen.
+   Set tabBarControllerMode = `tabBar`
+
+- [ ] Expected: Tab bar displayed without sidebar option - even if iPadOS would default do it
+
+5. Change app window size to correspond to iPhone view.
+
+- [ ] Expected: Tab bar displayed at the **bottom**
+
+6. Resize app to full screen.
+   Set tabBarControllerMode = `tabSidebar`, test on **iPad landscape** orientation
+
+- [ ] Expected: Navigation displayed as a **sidebar** on the leading edge
+
+7. Keep tabBarControllerMode = `tabSidebar`, test on **iPad portrait**
+
+- [ ] Expected: Sidebar adapts or collapses — tab items still accessible
+
+8. Change app window size to correspond to iPhone view.
+
+- [ ] Expected: Tab bar displayed at the **bottom** without sidebar option.
+
+9. Resize app to full screen.
+   Cycle through `automatic` → `tabBar` → `tabSidebar` → `automatic`
+
+- [ ] Expected: UI transitions immediately with each change, no crash or layout freeze
+
+10. Switch tabs (Tab1 ↔ Tab2) while cycling through all modes.
+
+- [ ] Expected: Tab switching works correctly in all three modes.
+
+---
+
+### Simple check on iPhone
+
+11. Launch the app and navigate to the **Tab Bar Controller Mode** screen.
+
+- [ ] Expected: Tab bar displayed at the bottom with Tab1 and Tab2. Picker defaults to `automatic`
+
+12.   Set tabBarControllerMode = `automatic`
+
+- [ ] Expected: Tab bar displayed at the **bottom**
+
+13.  Set tabBarControllerMode = `tabBar`
+
+- [ ] Expected: Tab bar displayed at the **bottom**
+
+14.  Set tabBarControllerMode = `tabSidebar`
+
+- [ ] Expected: Tab bar displayed at the **bottom**
