使用React Native進行排毒UI測試非常慢

Question

我們在運行wix / detox UI測試時遇到問題。 他們實在太慢了。

我們嘗試消除了所有可能的方法，禁用了所有后台進程，刪除了幾乎整個UI元素，嘗試禁用自動同步，但無濟於事。 這肯定比排毒文檔中的動畫要慢幾個數量級。

一個只有1個按鈕的簡單應用程序，單擊該按鈕大約需要1.5秒，而嘗試在我們的UI的某些部分上運行測試時，則需要40秒，但是按鈕和文本輸入很少。

結果是我們的整個測試套件運行了30分鍾（並且我們仍然沒有涵蓋我們想要的所有內容）。

典型日志：

Timed: animateWithDuration:delay:options:animations:completion:
Timed: animateWithDuration:delay:options:animations:completion:
Timed: animateWithDuration:delay:options:animations:completion:
Timed: animateWithDuration:delay:options:animations:completion:

（即使沒有動畫）

庫版本

排毒：6.0.0，6.0.4，7.0.0-alpha

反應本機：0.51.0

開玩笑：20.0.4

（我們也嘗試過摩卡咖啡，沒有變化）

就我而言 ，我有一個背景Redux Saga ，它每1秒運行一次（代碼在以yield call(delay, 1000)結束的循環中運行yield call(delay, 1000) 。

1秒間隔太短，無法排毒。 將延遲更改為2000可解決此問題。

計時器的松緊度可能取決於您擁有的背景雜物數量。 以2000毫秒的間隔運行2次sagas可能有效，但以相同的間隔運行100次sagas可能不可行。
