多線程執行測試用例

這裏以百度搜索為例，通過不同的瀏覽器來啟動不同的線程。

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，只能為 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     #創建線程
34     for browser,search in lists.items():
35         t = Thread(target=test_baidu,args=(browser,search))
36         threads.append(t)
37     #啟動線程
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同的瀏覽器環境執行測試用例。

多線程分布式執行測試用例

Selenium Grid本身不提供並發執行用例，只是提供多系統、多瀏覽器執行環境，鑒於並發執行需要用到多線程技術結合Grid來實現分布式並發執行測試用例。

在一臺主機上啟動一個hub主節點和一個node分支節點，另一臺主機啟動一個node分支節點如下所示：

• 啟動本機hub主機：java -jar selenium-server-standalone-2.53.0.jar -role hub [默認4444端口]
• 啟動本機node分支節點：java -jar selenium-server-standalone-2.53.0.jar -role node -port 5555
• 在遠程主機啟動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
