axe testing codes as dataframes and exceptions

in accessibility testing there are two modes:

1. one mode where you are testing a baseline
2. one mode where you have errors in the baseline, and trying to address to errors.

as we work through the tidy data representation of the axe codes we'll understand more of the landscape that axe covers in their automated tests. we'll have a birds eye of what is tested. these tests then need to make sense in automated testing scenarios beyond a 👍/👎. it is important that downstreams user can reason with continuous test results, and promptly resolve automated inaccessibles. improvements to the testing resolution should help developers resolve issues.

    import pandas, requests, markdown_it, io, networkx, matplotlib, numpy
    from toolz.curried import *; f = compose = compose_left

the axe codes

axe has tests for a varied accessibility conditions. the list of categories/tags are available @ https://raw.githubusercontent.com/dequelabs/axe-core/master/doc/rule-descriptions.md

    page = requests.get("https://raw.githubusercontent.com/dequelabs/axe-core/master/doc/rule-descriptions.md")
    MD = markdown_it.MarkdownIt("gfm-like")

load the rules into a dataframe

it is possible to extra tables as dataframes after we convert the markdown to html.

this next unit of work separates urls from their content.

    rules, *_ = pandas.read_html(io.StringIO(MD.render(page.text)), extract_links="body")
    rules = rules.join(
        rules[["ACT Rules", "Rule ID"]]
        .stack().apply(f(type([]), pandas.Series))
        .rename(columns=dict(enumerate("value url".split())))
        .unstack().pipe(
            lambda df: df[df.map(bool).any(axis=1)]
        )["url"].map(juxt(identity)), rsuffix="_url"
    )
    rules = rules.map(lambda x: x[0])
    rules.columns = pipe(rules.columns, map(f(str.lower, str.split, "_".join)))
    rules.issue_type =  rules.issue_type.str.replace("needs\s", "needs_", regex=True)
    rules = rules.set_index(rules.rule_id.str.replace("([.-])", "_", regex=True).pipe(pandas.Index, name="id"))

topology of the axe tag network

we find a high level understanding of the relationship between the tags when we look at different layouts of the network.s

    adjacency = tags.values.T @ tags.values
    adjacency = adjacency - adjacency * numpy.identity(adjacency.shape[0])
    G = pandas.DataFrame(adjacency, tags.columns, tags.columns).pipe(networkx.from_pandas_adjacency)

    networkx.draw_networkx(G, networkx.nx_agraph.graphviz_layout(G), alpha=.5)
    matplotlib.pyplot.gcf().set_size_inches(24, 24)
