Requirements

You will need the following prerequisites in order to use axe-selenium-python:

  • selenium >= 3.0.0

  • Python 2.7 or 3.6

  • The appropriate driver for the browser you intend to use, downloaded and added to your path, e.g. geckodriver for Firefox:

    • geckodriver <https://github.com/mozilla/geckodriver/releases>_ downloaded and added to your PATH <https://stackoverflow.com/questions/40208051/selenium-using-python-geckodriver-executable-needs-to-be-in-path#answer-40208762>_

Installation

To install axe-selenium-python:

$ pip install axe-selenium-python

Usage

.. code-block:: python

from selenium import webdriver from axe_selenium_python import Axe

def test_google(): driver = webdriver.Firefox() driver.get("http://www.google.com") axe = Axe(driver) # Inject axe-core javascript into page. axe.inject() # Run axe accessibility checks. results = axe.run() # Write results to file axe.write_results(results, 'a11y.json') driver.close() # Assert no violations are found assert len(results["violations"]) == 0, axe.report(results["violations"])

The method axe.run() accepts two parameters: context and options.

CHANGELOG ^^^^^^^^^^^^^^

version 2.1.5


Breaking changes:

  • The Axe class method execute has been renamed to run to mirror the method in the axe-core API.

version 2.1.0


  • Created package.json file to maintain axe-core dependency
  • Replaced unit tests with more meaningful integration tests
    • included a sample html file for integration tests

version 2.0.0


  • All functionalities that are not part of axe-core have been moved into a separate package, pytest-axe. This includes:

    • run_axe helper method
    • get_rules Axe class method
    • run Axe class method
    • impact_included Axe class method
    • analyze Axe class method.

The purpose of this change is to separate implementations that are specific to the Mozilla Firefox Test Engineering team, and leave the base axe-selenium-python package for a more broad use case. This package was modeled off of Deque's Java package, axe-selenium-java, and will now more closely mirror it.

All functionalities can still be utilized when using axe-selenium-python in conjunction with pytest-axe.

version 1.2.3


  • Added the analyze method to the Axe class. This method runs accessibility checks, and writes the JSON results to file based on the page URL and the timestamp.
  • Writing results to file can be enabled by setting the environment variable ACCESSIBILITY_REPORTING=true. The files will be written to results/ directory, which must be created if it does not already exist.
  • Accessibility checks can be disabled by setting the environment variable ACCESSIBILITY_DISABLED=true.

version 1.2.1


  • Updated axe to axe-core@2.6.1
  • Modified impact_included class method to reflect changes to the aXe API:
  • There are now only 3 impact levels: 'critical', 'serious', and 'minor'

version 1.0.0


  • Updated usage examples in README
  • Added docstrings to methods lacking documentation
  • Removed unused files

version 0.0.3


  • Added run method to Axe class to simplify the usage in existing test suites
  • run method includes the ability to set what impact level to test for: 'minor', 'moderate', 'severe', 'critical'

version 0.0.28


  • Added selenium instance as a class attribute
  • Changed file paths to OS independent structure
  • Fixed file read operations to use with keyword

version 0.0.21


  • Fixed include of aXe API file and references to it
  • Updated README
