多线程执行测试用例

这里以百度搜索为例，通过不同的浏览器来启动不同的线程。

 #!/usr/bin/env python

 # _*_ coding:utf-8 _*_

 __author__ = 'YinJia'

 from threading import Thread

 from selenium import webdriver

 from time import ctime,sleep

 #测试用例

 def test_baidu(browser,search):

     print('start: {0}'.format(ctime()))

     print('browser: {0}'.format(browser))

     if browser == "ie":

         driver =  webdriver.Ie()

     elif browser == "chrome":

         driver = webdriver.Chrome()

     elif browser == "ff":

         driver = webdriver.Firefox()

     else:

         print("browser参数有误，只能为 ie、ff、chrome")

     driver.get("http://www.baidu.com")

     driver.find_element_by_id("kw").send_keys(search)

     driver.find_element_by_id("su").click()

     sleep(2)

     driver.quit()

 if __name__=="__main__":

     lists = {'chrome':'C++','ie':'JAVA','ff':'python'}

     threads = []

     files = range(len(lists))

     #创建线程

     for browser,search in lists.items():

         t = Thread(target=test_baidu,args=(browser,search))

         threads.append(t)

     #启动线程

     for t in files:

         threads[t].start()

     for t in files:

         threads[t].join()

     print('end: {0}'.format(ctime()))

 运行结果：

 start: Mon Aug 20 00:09:50 2018

 browser: chrome

 start: Mon Aug 20 00:09:50 2018

 browser: ie

 start: Mon Aug 20 00:09:50 2018

 browser: ff

 end: Mon Aug 20 00:10:09 2018

可见同时运行三个不同的浏览器环境执行测试用例。

多线程分布式执行测试用例

Selenium Grid本身不提供并发执行用例，只是提供多系统、多浏览器执行环境，鉴于并发执行需要用到多线程技术结合Grid来实现分布式并发执行测试用例。

在一台主机上启动一个hub主节点和一个node分支节点，另一台主机启动一个node分支节点如下所示：

启动本机hub主机：java -jar selenium-server-standalone-2.53.0.jar -role hub [默认4444端口]
启动本机node分支节点：java -jar selenium-server-standalone-2.53.0.jar -role node -port 5555
在远程主机启动node分支节点：java -jar selenium-server-standalone-2.53.0.jar -role node -port 6666 -hub http://192.168.31.210:4444/grid/register

     dc = {'browserName':browser}

     driver = webdriver.Remote(command_executor=host,

                               desired_capabilities=dc)

     driver.get("http://www.baidu.com")

     driver.find_element_by_id("kw").send_keys(browser)

     driver.find_element_by_id("su").click()

     sleep(2)

     driver.quit()

 if __name__=="__main__":

     #启动参数（指定运行主机与浏览器）

     lists = {'http://127.0.0.1:4444/wd/hub':'chrome',

              'http://192.168.31.230:6666/wd/hub': 'internet explorer',

              'http://1127.0.0.1:5555/wd/hub': 'firefox'}

     threads = []

     files = range(len(lists))

     #创建线程

     for browser,search in lists.items():

         t = Thread(target=test_baidu,args=(browser,search))

         threads.append(t)

     #启动线程

     for t in files:

         threads[t].start()

     for t in files:
