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.py1.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:588402570** :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 = '' % 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:588402570** 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(request): global driver if driver is None: driver = webdriver.Firefox() def end(): driver.quit() request.addfinalizer(end) 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:588402570** 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 # ** 作者:上海-悠悠 QQ交流群:588402570** 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.
