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/registe
java -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 unittest
from selenium import webdriver
import 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 driver

global devicess

@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 ParametrizedTestCase
import os
import 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
