contrast-compass-axe-html-reporter

Creates an accessible HTML report from axe-core library AxeResults object listing violations, passes, incomplete and incompatible results. For color violations it will launch contrast compass with the context of issue to fix which can download new CSS or CSS changes to make.

Allows specifying report creation options: reportFileName, outputDir, outputDirPath, projectKey and customSummary.

This was forked from axe-html-reporter.

Notes:

• customSummary allows having html parameters
• outputDirPath allows specifying absolute path

Please check sample report output.

createHtmlReport returns HTML content that can be additionally used for specific integrations.

If only HTML content needed, user can pass doNotCreateReportFile: true to stop report file creation.

Suggestion on how to use this library if you don't need a report file but need only HTML it produces:

const reportHTML = createHtmlReport({
    results: rawAxeResults,
    options: {
        projectKey: 'I need only raw HTML',
        doNotCreateReportFile: true,
    },
});
console.log('reportHTML will have full content of HTML file.');
// suggestion on how to create file by yourself
if (!fs.existsSync('build/reports/saveReportHere.html')) {
    fs.mkdirSync('build/reports', {
        recursive: true,
    });
}
fs.writeFileSync('build/reports/saveReportHere.html', reportHTML);

Install

npm i -D contrast-compass-axe-html-reporter

Usage

Example usage in TestCafe

To run TestCafe tests with axe-core, install testcafe, axe-core and @testcafe-community/axe:

npm i -D contrast-compass-axe-html-reporter testcafe axe-core @testcafe-community/axe

For TestCafe example add the following clientScript in your .testcaferc.json config:

{
    "clientScripts": [{ "module": "axe-core/axe.min.js" }]
}

In the example bellow fileName is not passed. If fileName is not passed, HTML report will be created with default name accessibilityReport.html in artifacts directory.

See full TestCafe test example is bellow:

import { runAxe } from '@testcafe-community/axe';
import { createHtmlReport } from 'contrast-compass-axe-html-reporter';

fixture('TestCafe tests with Axe').page('http://example.com');

test('Automated accessibility testing', async (t) => {
    const axeContext = { exclude: [['select']] };
    const axeOptions = {
        rules: {
            'object-alt': { enabled: true },
            'role-img-alt': { enabled: true },
            'input-image-alt': { enabled: true },
            'image-alt': { enabled: true },
        },
    };
    const { error, results } = await runAxe(axeContext, axeOptions);
    await t.expect(error).notOk(`axe check failed with an error: ${error.message}`);
    // creates html report with the default file name `accessibilityReport.html`
    createHtmlReport({
        results,
        options: {
            projectKey: 'EXAMPLE',
        },
    });
});
