Playwright元素截图并保存至allure的实现示例

from io import BytesIO

import allure
from PIL import Image, ImageDraw
from playwright.sync_api import sync_playwright

def highlight_screenshot(page, element, tips='高亮截图'):
    # 滚动页面将元素移动到视野中
    element.scroll_into_view_if_needed()

    # 获取元素的位置信息
    box = element.bounding_box()
    x, y, width, height = box['x'], box['y'], box['width'], box['height']

    # 获取页面截图，并读取为PIL.Image对象
    png = page.screenshot(type='png')
    img = Image.open(BytesIO(png))

    # 利用元素的位置信息在页面截图中标记出元素
    draw = ImageDraw.Draw(img)
    draw.rectangle((x, y, x + width, y + height), outline='red', width=3)

    # 将标记后的截图保存至allure报告中
    with BytesIO() as output:
        img.save(output, format='png')
        allure.attach(output.getvalue(), tips, allure.attachment_type.PNG)

def test_screenshot():
    with sync_playwright() as pw:
        # 打开百度进行搜索
        browser = pw.chromium.launch()
        page = browser.new_page()
        page.goto('https://www.baidu.com')  # 跳转至百度页面
        page.fill('#kw', 'playwright 选择器')  # 搜索框中输入内容
        page.click('#su')  # 点击搜索按钮

        # 等待搜索结果加载
        page.wait_for_load_state('networkidle')

        # 判断当前页面显示10条搜索结果
        results = page.query_selector_all('h3')
        assert len(results) == 10

        # 将当前页面的搜索结果分别进行截图
        for i, result in enumerate(results):
            highlight_screenshot(page, result, f'搜索结果{i}')
