Selenium_多线程执行测试用例

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。

10 def test_baidu(browser,search):
11     print('start: {0}'.format(ctime()))
12     print('browser: {0}'.format(browser))
13     if browser == "ie":
14         driver =  webdriver.Ie()
15     elif browser == "chrome":
16         driver = webdriver.Chrome()
17     elif browser == "ff":
18         driver = webdriver.Firefox()
19     else:
20         print("browser参数有误，只能为 ie、ff、chrome")
21 
22     driver.get("http://www.baidu.com")
23     driver.find_element_by_id("kw").send_keys(search)
24     driver.find_element_by_id("su").click()
25     sleep(2)
26     driver.quit()
27 
28 if __name__=="__main__":
29     lists = {'chrome':'C++','ie':'JAVA','ff':'python'}
30     threads = []
31     files = range(len(lists))
32 
33     #创建线程
34     for browser,search in lists.items():
35         t = Thread(target=test_baidu,args=(browser,search))
36         threads.append(t)
37     #启动线程
38     for t in files:
39         threads[t].start()
40     for t in files:
41         threads[t].join()
42     print('end: {0}'.format(ctime()))
43 
44 运行结果：
45 start: Mon Aug 20 00:09:50 2018
46 browser: chrome
47 start: Mon Aug 20 00:09:50 2018
48 browser: ie
49 start: Mon Aug 20 00:09:50 2018
50 browser: ff
51 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
