环境准备
java安装,以及环境配置
python 3.4环境
selenium安装
pip install selenium
Chromedriver 要和本地的chrome浏览器匹配,点击下载
下载selenium-server-standalone点击下载
准备2台pc,如果是虚拟机,选择桥接,2台pc互相能ping通,本次测试为本机
开始部署
启动hub
java -jar selenium-server-standalone-v3.0.1.jar -role hub -port 4455

启动node
java -jar selenium-server-standalone-v3.0.1.jar -role node -port 5555 -hub http://192.168.0.102:4444/grid/registejava -jar selenium-server-standalone-v3.0.1.jar -role node -port 6666 -hub http://192.168.0.102:4444/grid/registe

其他node启动方式
java -Dwebdriver.ie.driver=D:\IEDriverServer.exe -jar selenium-server-standalone-2.37.0.jar -role node -hub [http://127.0.0.1:4444/grid/register](http://127.0.0.1:4444/grid/register) -maxSession 20 -browser "browserName=internet explorer,version=9,platform=WINDOWS,maxInstances=20" -port 5555
node是只运行IE,并且并发数是20,最多有20个IE浏览器在运行
查看grid信息
浏览器打开:http://hub_ip:4444/grid/console
可以查看hub信息,和已经连上的node信息

运行
封装的unittest, BaseRunner .py
import unittestfrom selenium import webdriverimport os PATH = lambda p: os.path.abspath( os.path.join(os.path.dirname(__file__), p) )def get_driver(device): chromedriver = PATH("../exe/chromedriver.exe") os.environ["webdriver.chrome.driver"] = chromedriver chrome_capabilities = { "browserName": "chrome", # 浏览器名称 "version": "", # 操作系统版本 "platform": "ANY", # 平台,这里可以是windows、linux、andriod等等 "javascriptEnabled": True, # 是否启用js "webdriver.chrome.driver": chromedriver } driver = webdriver.Remote(command_executor=device, desired_capabilities=chrome_capabilities) driver.maximize_window() # 将浏览器最大化 driver.get("https://www.baidu.com/") return driverclass ParametrizedTestCase(unittest.TestCase): def __init__(self, methodName='runTest', param=None): super(ParametrizedTestCase, self).__init__(methodName) global devicess devicess = param @classmethod def setUpClass(cls): pass cls.driver = get_driver(devicess) # cls.logTest = myLog().getLog("chrome") # 每个设备实例化一个日志记录器 def setUp(self): pass @classmethod def tearDownClass(cls): cls.driver.close() cls.driver.quit() pass def tearDown(self): pass @staticmethod def parametrize(testcase_klass, param=None): testloader = unittest.TestLoader() testnames = testloader.getTestCaseNames(testcase_klass) suite = unittest.TestSuite() for name in testnames: suite.addTest(testcase_klass(name, param=param)) return suite
编写测试用例
from Base.BaseRunner import ParametrizedTestCaseimport osimport time PATH = lambda p: os.path.abspath( os.path.join(os.path.dirname(__file__), p) )class HomeTest(ParametrizedTestCase): def testSearch(self): time.sleep(1) self.driver.find_element_by_id("kw").send_keys("selenium") time.sleep(2) self.driver.find_element_by_id("su").click() time.sleep(2) @classmethod def setUpClass(cls): super(HomeTest, cls).setUpClass() @classmethod def tearDownClass(cls): super(HomeTest, cls).tearDownClass()
运行
import unittestfrom multiprocessing.pool import Poolfrom Base.BaseRunner import ParametrizedTestCasefrom TestCase import HomeTestdef runner_pool(): devices_Pool = ['http://192.168.0.102:5555/wd/hub', 'http://192.168.0.102:6666/wd/hub'] pool = Pool(len(devices_Pool)) pool.map(run, devices_Pool) pool.close() pool.join()def run(device): suite = unittest.TestSuite() suite.addTest(ParametrizedTestCase.parametrize(HomeTest.HomeTest, param=device)) unittest.TextTestRunner(verbosity=2).run(suite)if __name__ == '__main__': runner_pool()
