axe-selenium-python

axe-selenium-python integrates aXe and selenium to enable automated web accessibility testing.

This version of axe-selenium-python is using [email protected].

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 downloaded and added to your PATH

Installation

To install axe-selenium-python:

$ pip install axe-selenium-python

Usage

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 3.0.1

• Upgraded to axe-core 3.5.5

version 3.0.0

• Upgraded to axe-core 3.5.3

version 2.1.5

Breaks backwards compatibility:

• 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 [email protected]
• 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
