selenium+python自动化91-多线程启动多个不同浏览器
一、前言
如果想用多个浏览器跑同一套测试代码，driver=webdriver.Firefox()这里的driver就不能写死了，可以把浏览器名称参数化。
后续如果想实现多线程同时启动浏览器执行用例，用前面讲的tomorrow模块，设置下线程数套用下就可以了
二、启动浏览器
1.为了实现多个浏览器的灵活切换，可以把启动浏览器写一个函数，参数用浏览器名称就行了
```
def startBrowser(name):
"""
打开浏览器函数，name参数："firefox"、"chrome"、"ie"、"phantomjs"
"""
try:
if name == "firefox" or name == "Firefox" or name == "ff":
print("start browser name :Firefox")
driver = webdriver.Firefox()
return driver
elif name == "chrome" or name == "Chrome":
print("start browser name :Chrome")
driver = webdriver.Chrome()
return driver
elif name == "ie" or name == "Ie":
print("start browser name :Ie")
driver = webdriver.Ie()
return driver
elif name == "phantomjs" or name == "Phantomjs":
print("start browser name :phantomjs")
driver = webdriver.PhantomJS()
return driver
else:
print("Not found this browser,You can use 'firefox', 'chrome', 'ie' or 'phantomjs'")
except Exception as msg:
print("启动浏览器出现异常：%s" % str(msg))
```
三、 多线程启动不同浏览器
1.代码参考：
```
# coding:utf-8
from selenium import webdriver
import time
from tomorrow import threads
def startBrowser(name):
"""
打开浏览器函数，"firefox"、"chrome"、"ie"、"phantomjs"
"""
try:
if name == "firefox" or name == "Firefox" or name == "ff":
print("start browser name :Firefox")
driver = webdriver.Firefox()
return driver
elif name == "chrome" or name == "Chrome":
print("start browser name :Chrome")
driver = webdriver.Chrome()
return driver
elif name == "ie" or name == "Ie":
print("start browser name :Ie")
driver = webdriver.Ie()
return driver
elif name == "phantomjs" or name == "Phantomjs":
print("start browser name :phantomjs")
driver = webdriver.PhantomJS()
return driver
else:
print("Not found this browser,You can use 'firefox', 'chrome', 'ie' or 'phantomjs'")
except Exception as msg:
print("启动浏览器出现异常：%s" % str(msg))
@threads(5)
def run_case(name):
driver = startBrowser(name)
driver.get("https://www.cnblogs.com/yoyoketang/")
time.sleep(3)
print(driver.title)
driver.quit()
if __name__ == "__main__":
names = ["chrome", "ff", "ie"]
for i in names:
run_case(i)
```
2.运行结果：
