+# Test Scenario: Simple navigation
+
+## Details
+
+**Description:** Verifies that programmatic tab navigation via the
+`selectTab` method on `useTabsNavigationContext` works correctly.
+Each tab renders its own `routeKey` as a label and exposes three
+buttons - **Select First**, **Select Second**, **Select Third** -
+that call `selectTab` with the corresponding route key. The test
+validates that tapping the tab bar items navigates normally, that
+the programmatic `selectTab` buttons switch to the correct tab
+from any starting tab, that the displayed `routeKey` label always
+matches the active tab, and that both interaction paths are
+consistent across platforms.
+
+**OS test creation version:** iOS: 18.6 and 26.5, Android: API Level 36.
+
+## E2E test
+
+Incomplete: The E2E test covers steps 1-13. Step 14 is omitted because Detox
+automatically waits for the UI layer to become idle. Due to this synchronization
+model, it cannot execute rapid tab switching sequentially before the previous
+transition animation finishes.
+
+## Prerequisites
+
+- iOS device or simulator
+- Android emulator or device
+
+## Steps
+
+### Baseline
+
+1. Launch the app and navigate to **Test simple navigation**.
+
+- [ ] Expected: Three tabs are visible in the tab bar -
+  **First**, **Second**, and **Third**. The **First** tab is
+  active. The content area displays the label `First`.
+
+---
+
+### Native tab-bar navigation
+
+2. Tap the **Second** tab in the tab bar.
+
+- [ ] Expected: The **Second** tab becomes active. The content
+  area displays the label `Second`.
+
+3. Tap the **Third** tab in the tab bar.
+
+- [ ] Expected: The **Third** tab becomes active. The content
+  area displays the label `Third`.
+
+4. Tap the **First** tab in the tab bar.
+
+- [ ] Expected: The **First** tab becomes active. The content
+  area displays the label `First`.
+
+---
+
+### Programmatic navigation via selectTab
+
+5. While on the **First** tab, tap **Select Second**.
+
+- [ ] Expected: The **Second** tab becomes active. The content
+  area displays the label `Second`.
+
+6. While on the **Second** tab, tap **Select Third**.
+
+- [ ] Expected: The **Third** tab becomes active. The content
+  area displays the label `Third`.
+
+7. While on the **Third** tab, tap **Select First**.
+
+- [ ] Expected: The **First** tab becomes active. The content
+  area displays the label `First`.
+
+---
+
+### Skipping tabs
+
+8. While on the **First** tab, tap **Select Third**.
+
+- [ ] Expected: The **Third** tab becomes active directly,
+  skipping **Second**. The content area displays the label
+  `Third`.
+
+9. While on the **Third** tab, tap **First** tab in the tab bar.
+
+- [ ] Expected: The **First** tab becomes active directly,
+  skipping **Second**. The content area displays the label
+  `First`.
+
+---
+
+### Mixed navigation (tab-bar then programmatic)
+
+10. Tap the **Second** tab in the tab bar.
+
+- [ ] Expected: The **Second** tab is active, label shows
+  `Second`.
+
+11. Tap **Select First** in the content area.
+
+- [ ] Expected: The **First** tab becomes active. The content
+  area displays the label `First`. The tab-bar item for
+  **First** is visually selected.
+
+---
+
+### Re-selecting the active tab (edge case)
+
+12. While on the **First** tab, tap the **First** tab bar item
+    again.
+
+- [ ] Expected: The **First** tab remains selected. The content
+  area still displays `First`. No crash or unexpected transition
+  occurs.
+
+13. While on the **First** tab, tap **Select First**.
+
+- [ ] Expected: The **First** tab remains selected. The content
+  area still displays `First`. No crash or unexpected state
+  change occurs.
+
+---
+
+### Rapid programmatic switching (edge case)
+
+14. From the **First** tab, tap **Select Second** and immediately
+    tap **Select Third** before the transition completes.
+
+- [ ] Expected: The final active tab is **Third**. The content
+  area displays the label `Third`. No crash or inconsistent
+  label is shown.
