selenium grid
一、Selenium Grid解决什么问题
可以分布式运行自动化测试用例,提高执行效率和解决兼容性测试的要求。二、运行机制selenium Grid使用Hub和Node模式,一台计算机作为Hub(管理中心)管理其他多个Node(节点)计算机。Hub负责将测试用例分发给多台Node计算机执行,并收集多台Node计算机执行结果的报告,汇总后提交一份总的测试报告。
有两种角色hub 和 node
Hub:在分布式测试模式中,只能有一台作为Hub的计算机。Hub负责管理测试脚本, 并负责发送脚本给其他Node节点。所有的Node节点计算机会在Hub计算机中先进行注册,注册成功后再和Hub计算机通信,Node节点计算机会告之Hub自己的相关信息。例如,Node节点的浏览器相关信息、最多并发数等。Hub计算机可以给自己分配执行测试用例的任务。Hub计算机分发的测试用例任务会在各个Node节点计算机执行。
Node:在分布式测试模式中,可以有一个或者多个Node节点。Node节点会打开本地的浏览器完成测试任务并返回测试结果给Hub。Node节点的操作系统和浏览器版本无需和Hub保持一致。在Node节点上可以同时打开多个浏览器并行执行测试任务
- Hub端(计算机A)的配置
打开http://selenium-release.storage.googleapis.com/index.html?path=2.51/地址,下载selenium-server-standalone- 2.53.1.jar,
java -jar selenium-server-standalone- 2.53.1.jar -role hub
或者
java -jar selenium-server-standalone- 2.53.1.jar -role hub -hubConfig hub.json
role参数:hub表示作为管理中心
port参数:hub服务器的端口号
hubConfig:hub各种配置的json文件路径。
运行后,会出现
2019-05-06 10:28:44.370:INFO::main: Logging initialized @670ms

10:28:44.450 INFO - Selenium Grid hub is up and running
其中,10:28:44.450为本机的ip地址,在浏览器中打开网址:
http://10.32.59.169:4444/grid/console/
可以看到Grid Console vxxx.xx.x以及下面的超链接 view config,但此时并没有任何节点信息,至此,hub端的配置已经完成。
- Node端的配置
在计算机B中运行
java -jar selenium-server-standalone- 2.53.1.jar -role webdriver -nodeConfig node.json
role参数:webdriver表示Node节点的名字
nodeConfig :node各种配置的json文件路径
运行后,有如下cosole信息:

这是后再次访问
http://10.32.59.169:4444/grid/console/
可以看到页面下多了两个tab,Browsers已经Configuration。可以看到刚才我们配置的节点信息。
编写分布式脚本
import unittest
from selenium import webdriver
from selenium.webdriver import DesiredCapabilities
from selenium.webdriver.common.keys import Keys
class PythonOrgSearch(unittest.TestCase):
def setUp(self):
# 使用本地webdrvier
# self.driver = webdriver.Firefox()
# 远程服务器的webdriver
self.driver = webdriver.Remote(
command_executor='http://10.32.59.169:4444/wd/hub', desired_capabilities=DesiredCapabilities.CHROME)
# 使用selenium grid执行测试
def test_search_in_python_org(self):
driver = self.driver
driver.get("http://www.python.org")
self.assertIn("Python", driver.title)
elem = driver.find_element_by_id("id-search-field")
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
def test_get_cookis(self):
driver = self.driver
driver.get("http://www.python.org")
driver.add_cookie({'name': 'forTest', 'value': 'dddd'})
print(driver.get_cookies())
def tearDown(self):
# self.driver.close()
self.driver.quit()
if __name__ == "__main__":
unittest.main()
