前言

做web自动化的小伙伴应该都希望在html报告中展示失败后的截图，提升报告的档次，pytest-html也可以生成带截图的报告。

conftest.py

1.失败截图可以写到conftest.py文件里，这样用例运行时，只要检测到用例实例，就调用截图的方法，并且把截图存到html报告上

# conftest.py文件

# coding:utf-8

from selenium import webdriver

import pytest

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" style="width:600px;height:300px;" ' \

                       '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

    if driver is None:

        driver = webdriver.Chrome()

    return driver

2.用例部分如下：

# test_01.py文件

from selenium import webdriver

import time

def test_yoyo_01(browser):

    browser.get("https://www.cnblogs.com/lixy-88428977/")

    time.sleep(2)

    t = browser.title

    assert t == "含笑半步颠√"

# test_02.py文件

from selenium import webdriver

import time

def test_yoyo_01(browser):

    browser.get("https://www.cnblogs.com/lixy-88428977/")

    time.sleep(2)

    t = browser.title

    assert "含笑半步颠√" in t
