【原】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：
