Python for UI automation (Selenium )

利用Python 來實現UI 自動化的功能.
適合需要反覆設定的測試.
例如設定WiFi Channel 的場合或是讓待測物反覆重開機.

2. Script example

1.      (Selenium module) Basic - get UI with JS

#優點: like browser and can record web via selenium IDE

#缺點: Slow and complex

from selenium import webdriver

import time

url="http://192.168.0.1//cgi-bin/luci/"

driver = webdriver.Firefox()

driver.get(url)

driver.find_element_by_xpath(u"//input[@type='button' and @value='reboot']").click()

time.sleep(2)

driver.quit()

2.      (Selenium module) Reboot device via UI 10000 times

# -*- coding: utf-8 -*-
# Function1: Login to UI
# Function2: Reboot device
# Function3: Print result output to file
