MrT*_*ime 4 python pytest python-3.x pytest-html
我在 Python 的 pytest 中动态设置报告名称和文件夹时遇到问题。例如:我已经在 2020-03-06 21:50 运行了所有 pytest 的测试,所以我想将我的报告存储在20200306name 的文件夹中report_2150.html。我希望它在测试完成后立即自动化并触发。
我在 VS Code 中工作,我的目标是与没有自动化经验的同事分享我的工作,所以我的目标是将其用作“单击测试开始”。

在当前情况下,报告是tmp_report.html在报告文件夹中创建的,但我不知道如何cleanup_report()在所有测试完成后强制运行tmp_report.html并且在文件夹中存在和完成。为了检查是否完整,我假设我必须验证所有 html 标签是否都有关闭(或至少<html>一个)。
有人可以帮我吗?如果您需要一些进一步的代码部分,我会尽快提供它们。
先感谢您!
您可以在pytest_configure钩子的自定义实现中自定义插件选项。将此示例代码放在conftest.py项目根目录中的文件中:
from datetime import datetime
from pathlib import Path
import pytest
@pytest.hookimpl(tryfirst=True)
def pytest_configure(config):
# set custom options only if none are provided from command line
if not config.option.htmlpath:
now = datetime.now()
# create report target dir
reports_dir = Path('reports', now.strftime('%Y%m%d'))
reports_dir.mkdir(parents=True, exist_ok=True)
# custom report file
report = reports_dir / f"report_{now.strftime('%H%M')}.html"
# adjust plugin options
config.option.htmlpath = report
config.option.self_contained_html = True

如果您想完全忽略从命令行传递的内容,请删除该if not config.option.htmlpath:条件。
如果你想坚持你当前的 impl,请注意在 Fixtures teardown 中,pytest-html还没有写报告。将代码从钩子cleanup_report的自定义实现中移动pytest_sessionfinish以确保pytest-html已经编写了默认报告文件:
@pytest.hookimpl(trylast=True)
def pytest_sessionfinish(session, exitstatus):
shutil.move(...)
