pytest 失败截图

 官方文档表示,html的内容支持HTML,json,jpg,url等多种形式。还举例说明。注意下面标记的地方,是报告内容变更需要我们替换的

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    pytest_html = item.config.pluginmanager.getplugin(‘html‘)
    outcome = yield
    report = outcome.get_result()
    extra = getattr(report, ‘extra‘, [])
    if report.when == ‘call‘:
        # always add url to report
        # screen = _capture_screenshot()
        filename = os.path.join(rootpath, ‘screen.png‘)  #获取截图文件位置
        extra.append(pytest_html.extras.png(filename))   #传入文件地址
        xfail = hasattr(report, ‘wasxfail‘)
        if (report.skipped and xfail) or (report.failed and not xfail):
            # only add additional html on failure
            extra.append(pytest_html.extras.html(‘<div>Additional HTML</div>‘))
        report.extra = extra


def _capture_screenshot():
    return driver.get_screenshot_as_file(‘screen.png‘)  # 截图并保存

运行  pytest --html=report.html,发现代码报错,

再看官方文档,发现给出了说明

pytest 失败截图

命令行更改运行方式: pytest --html=report.html --self-contained-html

发现运行成功,但是有warning

 报告截图是有的

 官方文档表明存入png格式为:extra.png(image),可能是因为我直接传的文件地址导致的问题

于是修改截图存入的数据,改为base64

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    pytest_html = item.config.pluginmanager.getplugin(‘html‘)
    outcome = yield
    report = outcome.get_result()
    extra = getattr(report, ‘extra‘, [])
    if report.when == ‘call‘:
        # always add url to report
        screen = _capture_screenshot() # 修改后的代码
        # filename = os.path.join(rootpath, ‘screen.png‘)
        extra.append(pytest_html.extras.png(screen)) # 修改后的代码
        xfail = hasattr(report, ‘wasxfail‘)
        if (report.skipped and xfail) or (report.failed and not xfail):
            # only add additional html on failure
            extra.append(pytest_html.extras.html(‘<div>Additional HTML</div>‘))
        report.extra = extra  


def _capture_screenshot():
    return driver.get_screenshot_as_base64() # 修改后的代码

运行  pytest --html=report.html --self-contained-html

pytest 失败截图

 有warning了,截图也成功

现在我们将截图的代码调整到失败判断中,只有失败的用例才需要截图

pytest 失败截图

 执行命令 pytest --html=report.html --self-contained-html

pytest 失败截图

只有失败的用例才会截图啦

最后源码为

from selenium import webdriver
import pytest

driver = None

@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    pytest_html = item.config.pluginmanager.getplugin(‘html‘)
    outcome = yield
    report = outcome.get_result()
    extra = getattr(report, ‘extra‘, [])
    if report.when == ‘call‘:
        xfail = hasattr(report, ‘wasxfail‘)
        if (report.skipped and xfail) or (report.failed and not xfail):
            screen = _capture_screenshot()
            extra.append(pytest_html.extras.png(screen))
            # only add additional html on failure
            extra.append(pytest_html.extras.html(‘<div>Additional HTML</div>‘))
        report.extra = extra


def _capture_screenshot():
    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
