1. Why does the Selenium script need to set the waiting mode? ——That is, what is his application background?
When using Selenium, the corresponding page elements cannot be displayed immediately during the browser loading process and element operations cannot be performed. A certain waiting time needs to be set to wait for the elements to appear. (To put it simply, it means setting a waiting time for the page elements to be loaded before the elements can be operated)
2. What is Selenium’s waiting method? How to write automated waiting scripts?
Selenium has 3 waiting methods.
1. Forced to wait for sleep
Set the approximate waiting sleep time. Regardless of whether the element is found or not, you must wait for the set sleep time to end.
2. Display waiting
A relatively smart waiting method , you can decide whether to terminate waiting by setting whether the waiting condition is met .
If the waiting element is found during the waiting time, the waiting can be terminated early; if the page element has not been found after the waiting time has elapsed, an exception will be thrown.
3. Implicit waiting
Use the implicitly_wait() method to set the waiting time . If an element is found during the waiting time, the waiting can be ended early. If the element is still not found after the waiting time, an exception will be thrown.
