嘿！selenium自动下载driver版本，得知道一下

Posted 2022-08-08 IT界的测试混子

闲来无事研究下selenium。发现了个东西，必须奔走相告。
那就是：selenium可以自动下载driver版本，浏览器升级也不怕啦。
当然，在这之前也有人出过这种教程，自己写脚本去下载driver。
我们来看看官网怎么说

使用Drivers的方式

https://www.selenium.dev/documentation/webdriver/getting_started/install_drivers/

• Driver Management Software 看着眼生。这就是Driver最新的使用方式。直接用Driver Management 来管理，随着浏览器的升级而升级。

来coding一下吧

• 先安装库

pip install webdriver-manager
pip install selenium

• 例子：

import time
from selenium import webdriver
from selenium.webdriver.edge.service import Service
from webdriver_manager.microsoft import  IEDriverManager

service = Service(executable_path=IEDriverManager().install())
driver = webdriver.Ie(service=service)
driver.get("https://www.baidu.com")
driver.maximize_window()
time.sleep(5)
driver.quit()

• 自动下载driver啦~~ 真棒。大家可以试下把浏览器升级再跑一遍。
  

• 另外webdriver-manager 支持selenium3.0、selenium4.0
  具体可以看github上的说明
  https://github.com/SergeyPirogov/webdriver_manager

• 也可以看下官方给的例子
  https://github.com/SeleniumHQ/seleniumhq.github.io/blob/trunk/examples/python/tests/getting_started/test_install_drivers.py

import pytest
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from selenium.webdriver.edge.service import Service as EdgeService
from selenium.webdriver.firefox.service import Service as FirefoxService
from selenium.webdriver.ie.service import Service as IEService
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.firefox import GeckoDriverManager
from webdriver_manager.microsoft import EdgeChromiumDriverManager
from webdriver_manager.microsoft import IEDriverManager

def test_driver_manager_chrome():
    service = ChromeService(executable_path=ChromeDriverManager().install())
    driver = webdriver.Chrome(service=service)
    driver.quit()

def test_edge_session():
    service = EdgeService(executable_path=EdgeChromiumDriverManager().install())
    driver = webdriver.Edge(service=service)
    driver.quit()


def test_firefox_session():
    service = FirefoxService(executable_path=GeckoDriverManager().install())
    driver = webdriver.Firefox(service=service)
    driver.quit()


@pytest.mark.skip(reason="only runs on Windows")
def test_ie_session():
    service = IEService(executable_path=IEDriverManager().install())
    driver = webdriver.Ie(service=service)
    driver.quit()
