python - selenium python 绑定(bind)是否需要 firefox

Question

您好，我刚刚下载并安装了 selenium，但是，我不知道如何让它工作，我正在使用以下示例作为测试....

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()         #this is where I hit the error
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.send_keys("selenium")
elem.send_keys(Keys.RETURN)
assert "Google" in driver.title
driver.close()

我的电脑上没有安装 firefox，这就是它给我错误的原因吗？ 这是我尝试运行它时得到的错误输出

下一行启动 Firefox 浏览器，所以是的，它需要安装 Firefox。

driver = webdriver.Firefox()  

如果您没有安装 Firefox，您可以使用其他浏览器:

webdriver.Opera
webdriver.Ie
webdriver.Chrome
...
