Python + + Unittest click a hyperlink to write Selenium test case

Test function: Click the link to the previous menu and secondary menu links Home Park blog site classification.

Problems encountered:

　　1. Click the cycle when the secondary menu, click on the first two menu under a previous menu page refreshes, and then positioning the second secondary menu under the same sub-menu level,

Will get an error: Can not find the second secondary menu, then the need for a menu to reposition assignment;

　　2. When too many secondary menu at the menu level, without visible area of ​​the page, then it will error: element not interactable, then need to slide the scroll bar.
