推荐答案

检查以下链接：

• Implicit Wait - 它通过轮询DOM来指示Web驱动程序等待一段时间。一旦声明了隐式等待，它将在Web驱动程序实例的整个生命周期中可用。默认情况下，该值为0.如果设置较长的默认值，则该行为将定期轮询DOM，具体取决于浏览器/驱动程序的实现。

• Implicit Wait - It instructs the web driver to wait for some time by poll the DOM. Once you declared implicit wait it will be available for the entire life of web driver instance. By default the value will be 0. If you set a longer default, then the behavior will poll the DOM on a periodic basis depending on the browser/driver implementation.

明确等待 + ExpectedConditions - 这是自定义条件。如果我们希望执行等待一段时间直到达到某种条件，它将被使用。

Explicit Wait + ExpectedConditions - It is the custom one. It will be used if we want the execution to wait for some time until some condition achieved.
