一、 pytest-html报告没有日志

• 解决办法 执行命名的时候加上--capture=sys
• 或者直接在pytest.ini 配置
  image.png
  addopts=-vsq --reruns 1 --reruns-delay 2 --html=output/report/html/report.html --self-contained-html --alluredir=output/report/allure_report --capture=sys

二、增加pytest-html报告的描述信息，失败发送邮件。

import pytest
import allure
import base64
import os
import sys
from datetime import datetime
import time
from testdatas import Comm_Datas as CD
from tools.send_mail import send_report
from py.xml import html
from common.constants import ENV_WEB_TXT_FILE, IMG_REPORT as img_dir, IMG_SCREEN_DIR


file_name = IMG_SCREEN_DIR + "{}{}_{}.png".format(os.sep, datetime.strftime(datetime.now(), "%Y%m%d%H%M%S"), "失败截图")

# 定义一个driver全局变量

    cells.insert(1, html.th('用例名称'))
    cells.insert(2, html.th('Test_nodeid'))
    cells.pop(2)

    cells.insert(1, html.td(report.description))
    cells.insert(2, html.td(report.nodeid))
    cells.pop(2)


def pytest_html_results_table_html(report, data):

        del data[:]
        data.append(html.div('通过的用例未捕获日志输出.', class_='empty log'))

• allure 单独截图也可以如下途径达到目的

allure失败用例截图 一
@pytest.hookimpl(tryfirst=True, hookwrapper=True)
def pytest_runtest_makereport(item, call):

    outcome = yield
    rep = outcome.get_result()
    if rep.when == "call" and rep.failed:
        # 判断用例是失败状态则进行截图
       driver.get_screenshot_as_file(file_name)
        with open(file_name, mode='rb') as f:
            file = f.read()
        allure.attach(file, f"失败截图{datetime.strftime(datetime.now(), "%Y%m%d%H%M%S"}", allure.attachment_type.PNG)
