pytest文档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

代码语言:javascript复制
# 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:646645429**
    :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():
    '''
    ** 作者:上海-悠悠 QQ交流群:646645429**
    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:

代码语言:javascript复制
# test_01.py文件

from selenium import webdriver
import time

#** 作者:上海-悠悠 QQ交流群:646645429**

def test_yoyo_01(browser:webdriver.Firefox):

    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:646645429**

def test_yoyo_01(browser:webdriver.Firefox):

    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

用例失败再重测1次,命令行加个参数就行了

$ py.test —rerun 1 —html=report.html —self-contained-html
