隐式等待(implicit)隐式等待是一种设置全局查找页面元素等待时间的方法。在此等待时间内，如果未找到指定元素，则会抛出异常。设置隐式等待只需一次，其语法如下：显示等待(explicit)显式等待是获取页面元素超时设置中使用频率最高的方法。其原理是通过设置最大等待时间和周期时间，按照周期时间检测是否出现等...
这篇文章 明确表达了自己对“Explicit is Better than Implicit”的理解: Being explicit means being concrete and specific instead of abstract and general. It also means not to hide the behavior of a function. Explicit 意味着要具体、特化,不要抽象、通用。同时不要隐藏函数的行为。 对于要具体、特化,文...
Explicit value means the non-zero value in a sparse tensor. If explicitVal is set, then all the non-zero values in the tensor have the same explicit value. The default value Attribute() indicates t...
Waiting is having the automated task execution elapse a certain amount of time before continuing with the next step. You should choose to use Explicit Waits or Implicit Waits. 等待是指在执行自动化的过程中,执行下一步之前所需要消耗的定额的时间。出了简单的sleep(),官方提供两种进阶用法。

C#implicit和explicit 今天在学可空类型的时候,看见两个关键字——implicit和explicit。 public staticimplicitoperator T? (T value); public static explicit operator T(T? value); 这两个关键字是一对用于类型转换的关键字 ... C# 显式 类型转换
