ios - 使用 React Native 进行排毒 UI 测试非常慢

我们在运行 wix/detox UI 测试时遇到问题。它们的速度慢得令人无法忍受。

我们尝试尽可能消除一切，我们禁用了所有后台进程，我们删除了几乎整个 UI 元素，我们尝试禁用自动同步，但没有任何帮助。它肯定比排毒文档中的动画慢一个数量级。

只有 1 个按钮的简单应用，单击该按钮大约需要 1.5 秒，当尝试在我们 UI 的某些部分上运行测试时，需要 40 秒，但按钮和文本输入很少。

结果是我们的整个测试套件运行了 30 分钟(我们仍然没有涵盖我们想要的所有内容)。

典型日志:

Timed: animateWithDuration:delayptions:animations:completion:
Timed: animateWithDuration:delayptions:animations:completion:
Timed: animateWithDuration:delayptions:animations:completion:
Timed: animateWithDuration:delayptions:animations:completion:

(即使没有动画)

库版本

排毒:6.0.0、6.0.4、7.0.0-alpha

react 原生:0.51.0

开玩笑:20.0.4

(我们也试过mocha，没有变化)

Best Answer-推荐答案

就我而言，我有背景 Redux Saga每 1 秒运行一次(代码在以 yield call(delay, 1000) 结尾的循环中运行。

1 秒的时间间隔太紧，Detox 无法释放。将延迟更改为 2000 即可解决问题。

计时器的紧密度可能取决于您拥有的背景 sagas 的数量。以 2000 毫秒的间隔运行 2 个 saga 可能有效，但以相同的间隔运行 100 个 saga 可能不行。
