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: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 = '<div><img src="data:image/png;base64,%s" alt="screenshot" style="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: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.
