    # 馴養了一隻比猴子聰明的 AI 測試猿 - 諶毅軒 {%hackmd MNcuRlXoQDak0uCmtaJKwA %} > https://medium.com/科科測試 > [name=科科測試] ###### tags: `MOPCON 2019` - [TOC] ## Agenda ### What's monkey > 用於檢測 App 穩定度、速度快、開發成本低 - Fuzz testing - For stabilitu - Crash, OOM, ANR - Advantage - Fast - Low-cost - 2016 - 2019 - 291/310 - Daily Crash Free Rate - 96% in 2016 - 99.9% in 2019 - Development - links [how to quick-start](https://github.com/dino-su/android-monkey-quick-start) [Monkey Test](https://github.com/MonkeyTestIt) #### Limitation > KKbox 使用者不會踩到 - Hard to reproduce - Random script - Random location - Random event - Minor issue ### What's APE > 利用物件偵測的方式去進行 > monkey學習後會去測試物件按鈕 #### APE with Object ... #### What We Want - CI (Continuous Intergration) - model 會隨著 CI 進步 - Increment dataset - Speed - 人力資源不夠 - Well integrity lifecycle - Cross-Platform - e.g. ios / android > 最終希望可以達到跨平台 ### TensorFlow object detection API #### Setup - Training - Local or cloud [(Google colab)](https://colab.research.google.com/notebooks/welcome.ipynb#recent=true) - TensorFlow - CPU or GPU > Ubuntu OS with GPU TensorFlw ### Training Inputs - Screenshots - Annotation tool(VoTT) - 主動式學習 - https://github.com/microsoft/VoTT - Transfer your training dataset to Records > Screenshots from firebase, annotation from VoTT ### Training Configs - Pre-trained model Zoo - Sample configs - e.g. - ssd_mobilenet_v2_quantized ### Training Config, saving places ... TensorBoard 會幫你看 training 有沒有異狀 > 優點:可以視覺化來看 training 過程狀況 ### Deploy #### Tensorflow Lite - adventage - cross-platform - fast - Convert checkpoint to TFLite ### Testing #### Tensorflow Lite 透過 Tf Lite 來撈 API 得到結果 Deploy Tensorflow Lite to Android and iOS ### How We Test - Loop in a specific event count - Screenshot - Feed the screenshot to TFLite Object Detection API - labels - actions Demo 功能: - 截圖 - 辨識 - 結果 - 互動 > 人家說 Live Demo 都會遇到問題 > [name=諶毅軒] ## 踩雷分享 ### About Environment TensorFlow-CPU vs TensorFlow-GPU - 3GB 顯卡使用 GPU 來做物件偵測,雖然說是中低階的顯卡,但最後的速度還是比 CPU 結果來的快 3 倍 ### Training Inputs #### VoTT VoTT 真的很方便,可以避免工人智慧。可以透過一個基本的 model 來做標記,人工再來微調 https://github.com/microsoft/VoTT 原先標記方法: 手動標記 - VoTT : 自動標記 => 手動人工*確認*,微調 ### Inference ### Case1:Necessary - 沒有偵測出play button ### Case2:Not-Allowed - 物件偵測錯誤 - model 有點 overfitting,造成把 Play Store 的 icon 看成 kkbox 的 icon 優點: - 很快速檢測出哪階段出現問題 (fast, effective) 缺點: - 需要下很多測試 ### F1 Measure - With a general formula - Detection - Boxes infromation of ground truth - F1 Score(new model) 跟 F1 Criteria(old model) 做比對看 F1 diff,正向分數居多則換成該model - 可以明顯的看出哪個部分訓練不好 - performance mesurement 越早做越好 > Do performance mesurement ASAP. ### About label - 將同一取向不同名稱的 label 壓縮成同一個 label (Android 碎片化的系統 dialog label 問題) > keep minimizing labels > Model is Learnable then we thought > 前期在做標注部分可以少一點 Label 沒關係 中間不知道為什麼所有的 Label 都不見了,一氣之下把所有的 Label 設定成 test_label,結果意外的正確率沒有下降太多 -> model 比我們想像的聰明 ### About color - 以 APP 的使用情境下,顏色不太重要,可以考量使用生態圈來調整顏色 - training 全部轉灰階 - Set model config to read image from grayscale - 甚至 grayscale 效果還比較好(因為元件相同、單純) > 最後結果:就算把顏色抽離還是可以學習 > 最後建議:大膽的把 Training 轉灰階 因為 image resizer 的關係,不同的裝置解析度會有差異,所以導致偵測不到。 - 既有的形狀全部都會被壓縮 > 若有最新消息和結果,會在官網上面和大家分享 ### Vision - ==ML is not that far away from us== - 多國語系測試 - 把每個語系的字串,丟去學習 ### Page Object - 優點: - 穩定度 - UI test 常出現的狀況: - isDisplay or isExist?
