Python Selenium 自动化实现截屏操作

Posted 2020-12-21 多测师_郑sir

一、今天小编就为大家分享一篇对 Python 获取屏幕截图的 3 种方法详解

1、采用 selenium 中的两种截图方法

• 方法一： save_screenshot()
• 方法二： get_screenshot_as_file()
  • 用法一样，都是截取浏览器当前窗口里的内容

from PIL import ImageGrab
import time

def screenshot_image1(webdriver, image_path):
    nowTime = time.strftime("%Y-%m-%d_%H-%M-%S")
    imageName = image_path + "/" + "bug_image{}.png".format(nowTime)
    webdriver.save_screenshot(imageName)

def screenshot_image2(webdriver, image_path):
    nowTime = time.strftime("%Y-%m-%d_%H-%M-%S")
    imageName = image_path + "/" + "bug_image{}.png".format(nowTime)
    webdriver.get_screenshot_as_file(imageName)

2、方法三：Windows 环境下截图需要用到 PIL 库，使用 pip 安装 PIL 库

• pip install pillow
• 函数参数介绍如下，默认为全屏截图

"""
第一个参数 开始截图的x坐标
第二个参数 开始截图的y坐标
第三个参数 结束截图的x坐标
第四个参数 结束截图的y坐标
"""
bbox = (0, 0, 1920, 1080)
im = ImageGrab.grab(bbox)   # grab() 默认截全屏

• 用例输出如下

import time
import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By
from screenshot.ScreenShotFunc import *

class Test_Baidu_Search(unittest.TestCase):

    def setUp(self) -> None:
        self.driver = webdriver.Chrome()
        self.driver.get("https://www.baidu.com")
        self.driver.maximize_window()
        self.driver.implicitly_wait(10)

    def tearDown(self) -> None:
        time.sleep(2)
        self.driver.quit()

    def test01(self):
        self.driver.find_element(By.ID, "kw").send_keys("Python")
        time.sleep(2)
        self.driver.find_element(By.ID, "su").click()
        # time.sleep(3)
        title = self.driver.title
        # 调用第一种方法实现截图
        """
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:work_docCodeFiledcs_class6screenshot_image"
            screenshot_image1(self.driver, image_path)
            raise AssertionError(E)
        """
        # 调用第二种方法实现截图
        """
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:work_docCodeFiledcs_class6screenshot_image"
            screenshot_image2(self.driver, image_path)
            raise AssertionError(E)
        """
        # 调用第三种方法实现截图
        try:
            self.assertIn("Python", title)
        except Exception as E:
            image_path = "D:work_docCodeFiledcs_class6screenshot_image"
            screen_shot(image_path)
            raise AssertionError(E)

if __name__ == ‘__main__‘:
    unittest.main()
