allure-python: allure.environment is missing in allure.py

My implementation of the fixture for adding information to the Environment widget:

from os import path
from typing import Any, Callable, Optional

from _pytest.fixtures import SubRequest
from pytest import fixture

ALLURE_ENVIRONMENT_PROPERTIES_FILE = 'environment.properties'
ALLUREDIR_OPTION = '--alluredir'


@fixture(scope='session', autouse=True)
def add_allure_environment_property(request: SubRequest) -> Optional[Callable]:

    environment_properties = dict()

    def maker(key: str, value: Any):
        environment_properties.update({key: value})

    yield maker

    alluredir = request.config.getoption(ALLUREDIR_OPTION)

    if not alluredir or not path.isdir(alluredir) or not environment_properties:
        return

    allure_env_path = path.join(alluredir, ALLURE_ENVIRONMENT_PROPERTIES_FILE)

    with open(allure_env_path, 'w') as _f:
        data = '\n'.join([f'{variable}={value}' for variable, value in environment_properties.items()])
        _f.write(data)

Example of usage:

@fixture(autouse=True)
def cenpprop(add_allure_environment_property: Callable) -> None:
    add_allure_environment_property('foo', 3)
    add_allure_environment_property('bar', 'baz')

As workaround it’s possible to create environment.xml and put it to alluredir after all tests executions finished. For pytest I have written next code:

# conftest.py
@pytest.fixture(scope="session")
def allure_env(tmpdir_factory):
    """Provide access to environment file."""
    env = tmpdir_factory.mktemp("allure").join("environment.xml")
    environment = lxml.etree.Element("environment")
    with open(env, "a") as env_xml:
        env_xml.write(lxml.etree.tounicode(environment, pretty_print=True))

    return str(env)


@pytest.fixture(scope="session", autouse=True)
def write_allure_env(request, allure_env):
    """Copy environment to alluredir."""
    yield

    alluredir = request.config.getoption("--alluredir")
    if os.path.isdir(alluredir):
        copyfile(allure_env, os.path.join(alluredir, "environment.xml"))

# common.py
import lxml

def set_env(allure_env: str, name: str, val: str) -> None:
    """Add entry to environment.xml."""
    parser = lxml.etree.XMLParser(remove_blank_text=True)
    tree = lxml.etree.parse(allure_env, parser)
    env = tree.getroot()

    exist = tree.xpath(
        f"/environment/parameter[key[text()='{name}'] "
        f"and value[text()='{val}']]"
    )

    if not exist:
        parameter = lxml.etree.SubElement(env, "parameter")
        name_node = lxml.etree.SubElement(parameter, "key")
        name_node.text = name
        value_node = lxml.etree.SubElement(parameter, "value")
        value_node.text = val

        with open(allure_env, "w") as env_xml:
            env_xml.write(lxml.etree.tounicode(env, pretty_print=True))

# test_something.py
import common

def test_example(request, allure_env):
    """Example test function."""
    env = request.config.getoption("--env")
    if env == "test":
        common.set_env(allure_env, "Environment", "Test")
    else:
        common.set_env(allure_env, "Environment", "Production")

Hope this will be helplul)

I made a ticket also with this not working. +1
