William Wang, a senior engineer, discusses the importance of automated testing in mobile app development and provides insights on how to implement testing strategies effectively. He addresses common challenges in UI automated testing and outlines the MVP pattern and API abstraction for validating mobile app workflows. The document also emphasizes the need for various types of validations, including end-to-end tests and unit tests for business logic and UI interactions.

- 4. Problems 1. 自動化測試很重要，但不知怎麼開始 2. 寫了UI自動化測試腳本，浪費好多撰寫成本 3. UI自動化腳本走不完所有路徑 4. UI自動化測試總是跑很慢 5. RD：Unit Test綠燈了！ QA：所以呢？可以吃嗎？

- 16. API Test in client E2E Validation • 確保輸入符合Server要求、回傳「格式」符合期望 How to validate • 輸入資料打API成功（不管回傳值正不正確） • 解析Server回傳資料「格式」正確 ■ Json參數、格式無誤 ■ 轉換成Model Class無誤

- 18. Model Unit Test E2E Validation • 業務邏輯、狀態測試 How to validate • 輸入各種Input以並驗證期望的Output ■ 模擬Presenter呼叫的狀況 ■ 不呼叫API，模擬API回傳的結果

- 20. Presenter Test E2E Validation • Presenter：Feature的高階抽象，驗證以下行為： ■ 接收View功能性事件 ■ 將功能委派給一個或多個Model ■ 通知View更新畫面 How to validate • 驗證當事件進來時有沒有呼叫正確的Model • 驗證Model Callback時有沒有呼叫正確的View

- 22. View UI Test E2E Validation • 操作UI、並驗證回饋正確 How to validate • 驗證UI事件進來時呼叫到對的Presenter方法 • 模擬Callback驗證更新View是否正確
