pytest添加运行失败截图
在conftest.py中,定义截图的方法,失败时自动截图,并将截图保存到html页面中
from common.base_driver import BaseDriver
import pytest
driver = None
#失败自动截图,展示到html报告中
@pytest.mark.hookwrapper
def pytest_runtest_makereport(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
#截图保存为base_64,展示在html中
def _capture_screenshot():
return driver.get_screenshot_as_base64()
#定义公共的fixture
@pytest.fixture
def common_driver():
global driver
driver = BaseDriver().base_driver()
yield driver
driver.close_app()
driver.quit()
#定义含有toast弹框的fixture
@pytest.fixture
def common_toast_driver():
global driver
driver = BaseDriver().base_driver(automationName="UIAutomator2")
yield driver
driver.close_app()
driver.quit()
注意的是fixture修饰的方法中,不要忘了global driver
运行之后显示测试报告的图片是宽度和高度过大,导致图片比较难看,因此我们需要优化下
自定义css
在html_reports目录下定义一个assets目录,在目录下将pytest-html插件源码中的style.css拷贝到assets下
使用F12查看报告的图片的位置,是在class="extra"下的img目录中
修改style.css,为了让这个样式优先级最高,加入!import
.extra div div img {
300px!important;
height: 500px!important;
}
修改main.py,使用--css, style.css路径
和--self-contained-html
(这个表示将我们定义的css样式合并到html页面中)
import pytest
import time
from common.conf_dir import html_reports_dir
cur_time = time.strftime("%Y-%m-%d_%H-%M-%S")
pytest.main([
#"--reruns=1",
#"--reruns-delay=10",
"-m", "fail",
"--junitxml", f"{html_reports_dir}/autotest_report_{cur_time}.xml",
"--html", f"{html_reports_dir}/autotest_report_{cur_time}.html",
"--css", f"{html_reports_dir}/assets/style.css",
"--self-contained-html"]
)
最终效果
这次报告看起来美观多了~
