本文介绍了Selenium WebDriver中隐式等待与显式等待的概念及其使用方法。隐式等待会在查找元素时持续轮询DOM直到超时。显式等待则为自定义条件，允许执行暂停直至满足特定条件或达到最大等待时间。

Implicit Wait: If elements are not immediately available, an implicit wait tells Web Driverto poll the DOM for a certain amount of time. The default setting is 0. Onceset, the implicit wait is set for the duration of the Web Driver object.

Explicit Wait: It is the custom one. It will be used if we want the execution to wait forsome time until some condition achieved.

wait = WebDriverWait(self.driver, timeout=timeout, poll_frequency=pollFrequency,
                     ignored_exceptions=[NoSuchElementException,
                                         ElementNotVisibleException,
                                         ElementNotSelectableException])
element = wait.until(EC.element_to_be_clickable((byType, locator)))

timeout is how much time you want to wait before time is out.

poll_frequency is the frequency of every poll.

ignored_exceptions is ignore those exceptions throwed.

EC is Expected Condition. element_to_be_clickable is the expected condition.

byType, locator is where the element is.
