What is axe-html-reporter?

The axe-html-reporter npm package is used to generate HTML reports from accessibility test results produced by the axe-core library. It helps in visualizing the accessibility issues found during testing in a user-friendly HTML format.

What are axe-html-reporter's main functionalities?

Generate HTML Report

This feature allows you to generate an HTML report from the results of an accessibility test run using axe-core. The `createHtmlReport` function takes the results object and options for the output directory and report file name, and generates an HTML file.

const { createHtmlReport } = require('axe-html-reporter');
const fs = require('fs');

const results = { /* axe-core results object */ };

createHtmlReport({
  results,
  options: {
    outputDir: 'reports',
    reportFileName: 'accessibility-report.html'
  }
}).then(() => {
  console.log('Report generated successfully');
}).catch(err => {
  console.error('Error generating report:', err);
});

Other packages similar to axe-html-reporter

pa11y-reporter-html

The pa11y-reporter-html package is used to generate HTML reports from Pa11y accessibility test results. It is similar to axe-html-reporter in that it provides a way to visualize accessibility issues in an HTML format. However, it is specifically designed to work with Pa11y, another popular accessibility testing tool.

html-reporter

The html-reporter package is a generic tool for generating HTML reports from various types of test results, not limited to accessibility testing. It provides a flexible way to create custom HTML reports, but may require more configuration compared to axe-html-reporter, which is specifically tailored for axe-core results.

README

axe-html-reporter

Creates an HTML report from Axe-core® library AxeResults object listing violations, passes, incomplete and incompatible results.

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

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 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 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 'axe-html-reporter';

fixture('TestCafe tests with Axe-core®').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',
        },
    });
});
