pytest失败截图加载到html报告内

conftest.py 里添加截图的逻辑

# coding:utf-8
import os
from selenium import webdriver
import pytest
from common.settings import PROXY_SERVER

driver = None


@pytest.mark.hookwrapper
def pytest_runtest_makereport(item):
    """
    当测试失败的时候，自动截图，展示到html报告中
    :param item:
    """
    pytest_html = item.config.pluginmanager.getplugin('html')
    outcome = yield
    report = outcome.get_result()
    extra = getattr(report, 'extra', [])

    if report.when == 'call' or report.when == "setup":
        xfail = hasattr(report, 'wasxfail')
        if (report.skipped and xfail) or (report.failed and not xfail):
            file_name = report.nodeid.replace("::", "_") + ".png"
            screen_img = _capture_screenshot()
            if file_name:
                html = '<div><img src="data:image/png;base64,%s" alt="screenshot"  ' \
                       'onclick="window.open(this.src)" align="right"/></div>' % screen_img
                extra.append(pytest_html.extras.html(html))
        report.extra = extra


def _capture_screenshot():
    '''
    截图保存为base64，展示到html中
    :return:
    '''
    return driver.get_screenshot_as_base64()


@pytest.fixture(scope='session', autouse=True)
def browser():
    global driver
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--proxy-server={}'.format(PROXY_SERVER))
    if os.getenv("DOCKER") == "True":
        chrome_options.add_argument("--headless")
        chrome_options.add_argument("--disable-gpu")
        chrome_options.add_argument("--no-sandbox")
        chrome_options.add_argument("--ignore-certificate-errors")
    driver = webdriver.Chrome(options=chrome_options)
    driver.implicitly_wait(30)
    yield driver
    driver.quit()

　　case 级别调用时

from page_object.application.app_create import AppCreatePage


class TestCreateApp():

    def 测试创建应用(self, browser):
        create_page = AppCreatePage(browser)
        create_page.open_create_app()
        create_page.create_app()

　　这里吧driver当做一个参数传给类，方便于page object模式开发写UI自动化
