pytest-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 :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.Firefox() 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/yoyoketang/") time.sleep(2) t = browser.title assert t == "上海-悠悠" # test_02.py文件 from selenium import webdriver import time def test_yoyo_01(browser): 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

失败重跑需要依赖pytest-rerunfailures插件，使用pip安装就行

$ pip install pytest-rerunfailures

用例失败再重跑1次,命令行加个参数--reruns就行了

$ py.test --reruns 1 --html=report.html --self-contained-html

关于reruns参数的2个用法

re-run failing tests to eliminate flaky failures:
  --reruns=RERUNS       number of times to re-run failed tests. defaults to 0.
  --reruns-delay=RERUNS_DELAY
                        add time (seconds) delay between reruns.
