# Advanced Mobile Prompting

> Specialized commands for mobile (iOS & Android) tests — app lifecycle, device gestures, and toast assertions

## Overview

Mobile tests are authored as **natural-language steps**. In addition to the usual
taps, types, and scrolls, Spur recognizes a set of specialized mobile commands for
controlling the **app lifecycle**, simulating **device gestures**, and asserting on
**toast messages**. You write them as ordinary steps — Spur maps your phrasing to the
right action.

| Command                                                                                          | What it does                                                  | iOS | Android |
| ------------------------------------------------------------------------------------------------ | ------------------------------------------------------------- | :-: | :-----: |
| [Activate App](/authoring-tests/test-side-peek/step-types/mobile/activate-app)                   | Bring the app under test back to the foreground               |  ✅  |    ✅    |
| [Restart App](/authoring-tests/test-side-peek/step-types/mobile/restart-app)                     | Terminate and cold-relaunch the app (or another app)          |  ✅  |    ✅    |
| [Shake Device](/authoring-tests/test-side-peek/step-types/mobile/shake-device)                   | Simulate a physical device shake                              |  ❌  |    ✅    |
| [Flip Device](/authoring-tests/test-side-peek/step-types/mobile/flip)                            | Emulate flipping the device face-up ↔ face-down               |  ❌  |    ✅    |
| [Expect Toast / Expect No Toast](/authoring-tests/test-side-peek/step-types/mobile/expect-toast) | Assert that a transient toast message did (or did not) appear |  ✅  |    ✅    |

<Note>
  These commands apply only to **mobile** tests (iOS and Android). They have no effect
  on web tests.
