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

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，"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))

多线程启动不同浏览器

1.代码参考：

# coding:utf-8from selenium import webdriverimport timefrom tomorrow import threadsdef 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：
