I have a problem with setting report name and folder with it dynamically in Python\'s pytest. For example: I\'ve run all pytest\'s tests @ 2020-03-06 21:50 so I\'d like to have

You can customize the plugin options in a custom impl of the pytest_configure hook. Put this example code in a conftest.py file in your project root dir:

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

If you want to completely ignore what's passed from command line, remove the if not config.option.htmlpath: condition.

If you want to stick with your current impl, notice that on fixtures teardown, pytest-html hasn't written the report yet. Move the code from cleanup_report to a custom impl of the pytest_sessionfinish hook to ensure pytest-html has already written the default report file:

@pytest.hookimpl(trylast=True)
def pytest_sessionfinish(session, exitstatus):
    shutil.move(...)
