pytest插件:pytest-html (执行用例失败后,自动截图到报告 + 失败用例重跑)
1、先pip安装插件: pytest-html、pytest-rerunfailures
2、用例执行失败自动截图到报告内 ,这个其实可以写到conftest.py文件。
当运行用例时遇到错误就会自己调用截图方法,并把截图存到html报告内
#固定脚本,可根据需要更改
from selenium import webdriver import pytest import os driver = None @pytest.mark.hookwrapper def pytest_runtest_makereport(item): """ Extends the PyTest Plugin to take and embed screenshot in html report, whenever test fails. :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): dirpng=r'./report/png/' if os.path.exists(dirpng) and os.path.isdir(dirpng): pass else: os.mkdir(dirpng) file_name = dirpng + report.nodeid.replace("::", "_")+".png" file_name1=r'./png/'+ report.nodeid.replace("::", "_")+".png" _capture_screenshot(file_name) if file_name: html = '<div><img src="%s" alt="screenshot" style="width:304px;height:228px;" ' \ 'onclick="window.open(this.src)" align="right"/></div>' % file_name1 extra.append(pytest_html.extras.html(html)) report.extra = extra def _capture_screenshot(name): driver.get_screenshot_as_file(name) @pytest.fixture(scope='session', autouse=True) def browser(): global driver if driver is None: driver = webdriver.Chrome() return driver
3、失败重跑操作(以下2种方法)
pytest --reruns 重试次数
pytest --reruns 重试次数 --reruns-delay 次数之间的延时设置(单位:秒)
例:
cmd: pytest --html=./report/test_report.html -v --reruns 2 --reruns-delay 3
(表示失败用例重跑2次,且重跑延迟间隔时间3s,输入报告test_report.html到用例所属目录的同级文件夹report文件夹下)
