We all know that Test is important ...

Problems1. 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？

API Test in clientE2E 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
