Project description

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

This version of axe-selenium-python is using axe-core@3.1.1.

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.

For more information on context and options, view the aXe documentation here.

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
