allure-pytest-ext 2.14.2

Extensions for allure-pytest: propagate step failures and aggregate step failures

allure-pytest-ext

Extensions for allure-pytest focused on test ergonomics and clear reporting.

This plugin adds two capabilities on top of Allure's standard API:

• with allure.step(title, propagate=True, ...): make steps fail even if exceptions inside are caught by user code; optionally re-raise on the parent after the step finishes.
• with allure.aggregate_step(title): run all child steps and aggregate failures into a single error raised at the end.

Links

• Live Allure demo report (GitHub Pages): pytest-allure-propagate report
• The demo report is generated automatically on tag creation (release workflow), and can also be built manually via the "Allure Pages" workflow.
• Official Allure docs: https://allurereport.org
• Allure pytest page on PyPI: https://pypi.org/project/allure-pytest/

Installation

Official (uv)

uv add allure-pytest-ext

Alternative (pip)

pip install allure-pytest-ext

Compatibility

• Python: 3.8 – 3.13
• Allure pytest adapter: designed for allure-pytest versions 2.13.3–2.14.2. At runtime, the plugin emits a warning if the installed allure-pytest version is outside this range.

Quick start

1. Write tests using the plugin’s features where they add value in your flow.

import pytest
import allure


def test_propagate_caught_error() -> None:
    # Your code catches the error locally, but you still want the step to fail
    # and the error to surface at the test level.
    with allure.step('parnet-step')
        try:
            with allure.step("child-step", propagate=True):
                raise ValueError("missing required field: id")
        except Exception:
            ...
            # Not only the child-step will apper red,
            # also the parnet-step will apper yellow, but It won't raise an expecptiom


def test_aggregate_sibling_failures() -> None:
    # Run independent checks and see all failures together rather than failing fast.
    with allure.aggregate_step("check downstream services"):
        with allure.step("service A health"):
            raise RuntimeError("timeout")
        with allure.step("service B schema"):
            ... # this step will run
        # now the step `check downstream services` will rise the expection

2. Run tests and generate Allure results folder.

uv run pytest --alluredir=.allure-results --ignore=tests/test_mock.py
# or
pytest --alluredir=.allure-results --ignore=tests/test_mock.py

3. Serve the report locally.

allure serve .allure-results

4. Optional: log step start/end in test logs

Enable source logger messages for step START/END via any of the following:

pytest --alluredir=.allure-results --ignore=tests/test_mock.py --allure-log-steps

# pytest.ini
allure_log_steps = true

ALLURE_EXT_LOG_STEPS=1 pytest --alluredir=.allure-results --ignore=tests/test_mock.py

API additions

• allure.step(title: str, propagate: bool = False, raise_on_parent: bool = False)

  • propagate=True: if any exception occurs inside the step and is caught by test code, the step is still marked failed.
  • raise_on_parent=True: when used together with propagate=True, re-raise the first observed exception after the step exits (affects the parent scope).

• allure.aggregate_step(title: str)

  • Executes all nested steps even if some fail. At the end, raises an aggregated error comprising all child failures.
  • The aggregated error type is allure_pytest_ext.plugin.AggregateError.

Configuration

• Source logger step events (START/END) can be enabled via any of:

  • CLI: --allure-log-steps
  • pytest.ini: allure_log_steps = true
  • Env: ALLURE_EXT_LOG_STEPS=1 (or ALLURE_LOG_STEPS=1)

• Debug tracing (prints when exceptions are seen inside steps):

  • Env: ALLURE_EXT_DEBUG_TRACE=1
