python+selenium+Chrome Web自动化测试进阶学习1

python+selenium+Chrome Web自动化测试进阶学习1

环境安装（mac）

1.python3.7 (网上教程一堆)+pycharm（写python的工具） 2.selenium3.141.0 pip install selenium=3.141.0 安装完成后查看一下selenium是否安装成功 pip show selenium 3.ChromeDriver 先查看一下Chrome的版本 点击浏览器右上角三个点->设置->关于Chrome 然后去这个网址下寻找对应的chromedriver下载 放到/usr/local/bin 终端输入vim ~/.bash_profile添加环境变量 export PATH=$PATH:ChromeDriver 别忘记使文件生效 source ~/.bash_profile 打开pycharm 写点代码试试呢

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://www.baidu.com")

报错就这样写试试呢

from selenium import webdriver
#路径是你放Chromedriver的地方
driver = webdriver.Chrome(/Users/user/PycharmProjects/AutoTest/chromedriver)
driver.get("https://www.baidu.com")

然后运行 就可以自动打开百度页面

写个验证 看看打开的是不是百度的页面 跳转的是否成功

from selenium import webdriver
from  selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome(/Users/user/PycharmProjects/AutoTest/chromedriver)
driver.get("https://www.baidu.com")
title=EC.title_is(u百度一下，你就知道)
#返回类型为Boolean值
print(title(driver))
#关闭浏览器
driver.quit()

运行结果：

from selenium import webdriver
from  selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome(/Users/user/PycharmProjects/AutoTest/chromedriver)
driver.get("https://www.baidu.com")
title=EC.title_is(u百度一下，你就知道)
print(title(driver))
#其中expected_conditions模块，提供了text_to_be_present_in_element提供了text_to_be_present_in_element_value判断元素的value值

locator = (class name, mnav)
text = u"新闻"
result = EC.text_to_be_present_in_element(locator, text)(driver)
print(result)

# 下面是失败的案例
text1 = u"新闻告诉"
result1 = EC.text_to_be_present_in_element(locator, text1)(driver)
print(result1)

locator2 = ("id", "su")
text2 = u"百度一下"
result2 = EC.text_to_be_present_in_element_value(locator2, text2)(driver)
print(result2)

driver.quit()
