This blog post introduces automated testing, whether or selenium are the four ways to wait Appium, rational use of waiting for the stability of the code, testing efficiency has greatly improved
Implicit wait: is when trying to find an element of, if not immediately able to find the time to wait for a fixed length. The default setting is 0 seconds. Once the wait time provided implicit, its scope is the whole life cycle of the object instance Webdriver
display wait: wait condition is defined, only the trigger condition, before the implementation of subsequent code.
Forced to wait: Specifies the length of waiting time fixed in seconds
Fluent Wait: He is a display with a waiting, he allows us to define the polling interval, ignore any abnormality, timeout, etc.
Second, the example code
