1, can not start the browser, error is as follows:

(Driver info:chromedriver=2.10.267521,platform=windows NT 6.3 x86_64)

How to resolve:

Webdriver when initializing, specify the path where the browser is located

When declaring Webdriver, add a sentence and run it again:

Path = "C:\Program Files (x86) \google\chrome\application\chromedriver.exe"

Self.driver = Webdriver. Chrome (Executable_path=path)

2. The element cannot be found according to the position:

(1) Possible situation one: because the window of the current browser is switched (the new Jump window).

Workaround: Before positioning, switch the window first

Handles = driver.window_handles # all Windows
print ' * ' *20,handles
For handle in handles:
If Handle!=driver.current_window_handle:
print ' Switch to ', handle
Driver.switch_to_window (handle)
Print Driver.current_window_handle # Printing window Handle--name
Break

(2) Possible situation two: Because the currently positioned IFrame has changed.

Workaround: Before positioning, switch the frame

Driver.switch_to_frame ("Rightframe")

(3) Possible three: run too fast, the page is not fully loaded.

Workaround: Hibernate for 1 seconds (or more seconds) before locating

Time.sleep (1)
