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-8from selenium import webdriverimport pytestdriver = None@pytest.mark.hookwrapperdef 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 = extradef _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 driver2.用例部分如下：
# test_01.py文件
from selenium import webdriverimport timedef 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 webdriverimport timedef 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报告展示
1.cmd打开，cd到用例的目录，执行指令
$ pytest --html=report.html --self-contained-html / python3 -m pytest --html=report.html --self-contained-html
2.生成报告如下
失败重试
用例失败再重测1次,命令行加个参数就行了
$ py.test --rerun 1 --html=report.html --self-contained-html
