ios - 使用 React Native 进行排毒 UI 测试非常慢
<p><p>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。</p>
<p>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。</p>
<p>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。</p>
<p>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)。</p>

<p><p><strong>就我而言</strong>,我有背景 <a href="https://github.com/redux-saga/redux-saga" rel="noreferrer noopener nofollow">Redux Saga</a>每 1 秒运行一次(代码在以 <code>yield call(delay, 1000)</code> 结尾的循环中运行。</p>
<p>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。</p>
<p>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。</p></p>
