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
