Common Mobile Visual Testing

🕵 Mobile Visual & Behavioral Testing

Priority: P1 (HIGH)

> [!IMPORTANT]

> Tier 2 (Methodology): Strategy mobile UI/UX audit.

> Tier 3 (Domain): i18n, A11y (Dynamic Type), Platform (Notch/RTL).

🧪 Testing Mindset

Analyze diff + answer:

• Change? (Affected screen, logic path)
• Break? (Regression, state transition)
• Visual Audit: Truncate, align, z-order, color.
• Behavioral Audit: Tap target, nav, data accuracy.

📋 Scenario Matrix

| Change Type | Scenarios to Run |

| :--- | :--- |

| UI/Styling | Visual Audit + Dark Mode + QoS Check (CPU/Mem) |

| Navigation | User Flow + Deep Link + Z-Order |

| Lists/Grids | Scroll Test + Pagination + Empty State |

| i18n/Locale | RTL + Truncate + Locale Logic |

| Accessibility | Dynamic Type + High Contrast + Permission Reason |

🛠️ Core Tool Mapping

| Scenario | Appium Tool |

| :--- | :--- |

| System Alert | appium_alert (check hierarchy first) |

| Performance | appium_mobile_performance_data (monitor during flow) |

| Visual Check | appium_screenshot (base/diff) |

| Layout Audit | appium_get_source (hierarchy/aria) |

🚫 Anti-Patterns

• Ignore QoS: Apps crash/lag under load. MUST check and report QoS from appium_mobile_performance_data (scroll/video).
• Blind Tap: Check state before interact. Use appium_screenshot.
• Alert Paralysis: Unexpected alert? Use appium_alert → accept/dismiss.
• Happy-Path Bias: Never ignore Empty, Loading, or Error state.
• Deep Link Neglect: Verify "Cold Start" via deep link.
• Single-Device Tunnel Vision: Verify smallest/largest screen size.
