pytest文档8-html报告报错截图+失败重跑
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 ** 作者:上海-悠悠 QQ交流群:646645429** :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(): ''' ** 作者:上海-悠悠 QQ交流群:646645429** 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.Firefox() return driver
2.用例部分如下:
# test_01.py文件 from selenium import webdriver import time #** 作者:上海-悠悠 QQ交流群:646645429** def test_yoyo_01(browser:webdriver.Firefox): browser.get("https://www.cnblogs.com/yoyoketang/") time.sleep(2) t = browser.title assert t == "上海-悠悠" # test_02.py文件 from selenium import webdriver import time # ** 作者:上海-悠悠 QQ交流群:646645429** def test_yoyo_01(browser:webdriver.Firefox): browser.get("https://www.cnblogs.com/yoyoketang/") time.sleep(2) t = browser.title assert "上海-悠悠" 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
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
