ios - 使用 React Native 进行 Detox UI 测试非常慢

Question

我们在运行 wix/detox UI 测试时遇到问题。它们慢得令人难以忍受。

我们试图消除所有可能的东西，我们禁用了所有后台进程，我们删除了几乎整个 UI 元素，我们试图禁用自动同步但没有任何帮助。它绝对比排毒文档中的动画慢一个数量级。

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

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

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:

(即使没有动画)

库版本

排毒:6.0.0、6.0.4、7.0.0-alpha

native react :0.51.0

开玩笑:20.0.4

(我们也尝试了mocha，没有变化)

在我的例子中，我有一个背景 Redux Saga每 1 秒运行一次(代码在以 yield call(delay, 1000) 结束的循环中运行。

1 秒的间隔时间太短，无法免费使用 Detox。将延迟更改为 2000 解决了问题。

计时器的严密性可能取决于您拥有的背景故事的数量。以 2000 毫秒的间隔运行 2 个 sagas 可能有效，但以相同的间隔运行 100 个 sagas 可能行不通。
