Selenium_多線程執行測試用例

多線程執行測試用例

這裏以百度搜索爲例，經過不一樣的瀏覽器來啓動不一樣的線程。

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參數有誤，只能爲 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     #建立線程
34     for browser,search in lists.items():
35         t = Thread(target=test_baidu,args=(browser,search))
36         threads.append(t)
37     #啓動線程
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 運行結果：
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

 可見同時運行三個不一樣的瀏覽器環境執行測試用例。

多線程分佈式執行測試用例

Selenium Grid自己不提供併發執行用例，只是提供多系統、多瀏覽器執行環境，鑑於併發執行須要用到多線程技術結合Grid來實現分佈式併發執行測試用例。

在一臺主機上啓動一個hub主節點和一個node分支節點，另外一臺主機啓動一個node分支節點以下所示：

• 啓動本機hub主機：java -jar selenium-server-standalone-2.53.0.jar -role hub [默認4444端口]
• 啓動本機node分支節點：java -jar selenium-server-standalone-2.53.0.jar -role node -port 5555        
• 在遠程主機啓動node分支節點：java -jar selenium-server-standalone-2.53.0.jar -role node -port 6666 -hub http://192.168.31.210:4444/grid/register
