Java-a11y

Accessibility Automation for Web Apps with Java and Selenium Webdriver.

Note If you are using version 2.1.4 and below, refer readme

This project uses HTML CodeSniffer and Deque Axe

HTML CodeSniffer : checks HTML source code and detects any Accessibility violations. Comes with standards that cover the three (A, AA & AAA) conformance levels of the W3C’s Web Content Accessibility Guidelines (WCAG) 2.1 and the U.S. Section 508 legislation.

Deque Axe : World’s leading digital accessibility toolkit. Powerful and accurate accessibility toolkit can get you to 80% issue coverage, or more, during development.

Features

1. Simple & Easy to use
2. No need of prior knowledge on Accessibility
3. Works with Java Selenium Webdriver
4. Rich Reporting
5. Open source

Getting Started

Using HTML CodeSniffer

Create object of HtmlCsRunner as below. driver will be your WebDriver instance.

HtmlCsRunner htmlCsRunner = new HtmlCsRunner(driver);;

Once after you navigated to any page/popup with Selenium Webdriver execute Accessibility on that particular page/popup

htmlCsRunner.execute();

The above execute will also generate JSON Report on accessibility issues at page/popup level

Once after all the tests executed, you can call the below method to generate consolidated HTML Report on accessibility issues

htmlCsRunner.generateHtmlReport();

Below is junit example with reporting.

import freemarker.template.TemplateException;
import io.github.bonigarcia.wdm.ChromeDriverManager;
import io.github.sridharbandi.HtmlCsRunner;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import java.io.IOException;
import java.net.URISyntaxException;
import java.time.Duration;

/**
 * A sample test to demonstrate
 */
public class Example {

    private WebDriver driver;
    private static HtmlCsRunner htmlCsRunner;

    @BeforeEach
    public void beforeTest() {
        ChromeDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        driver.manage().timeouts().pageLoadTimeout(Duration.ofSeconds(60));
        driver.manage().window().fullscreen();
        htmlCsRunner = new HtmlCsRunner(driver);

    }

    @AfterEach
    public void tearDown() throws IOException {
        htmlCsRunner.execute();
        driver.quit();
    }

    @AfterAll
    public static void generateReport() throws IOException {
        htmlCsRunner.generateHtmlReport();
    }

    @Test
    public void googleTest() {
        driver.get("https://www.google.com/");
    }

    @Test
    public void stockTest() {
        driver.get("https://www.istockphoto.com/");
    }
}

By default, it will check against WCAG2AA standards. However, you can configure it to standard you want to test with

htmlCsRunner.setStandard(HTMLCS.WCAG2A);

HTML Reports will be generated under ./target/java-a11y/htmlcs folder.

Page Report

Using Deque Axe

Create object of AxeRunner as below. driver will be your WebDriver instance.

AxeRunner axeRunner = new AxeRunner(driver);

Once after you navigated to any page/popup with Selenium Webdriver execute Accessibility on that particular page/popup

axeRunner.execute();

The above execute will also generate JSON Report on accessibility issues at page/popup level

Once after all the tests executed, you can call the below method to generate consolidated HTML Report on accessibility issues

axeRunner.generateHtmlReport();

Below is junit example with reporting.

import freemarker.template.TemplateException;
import io.github.bonigarcia.wdm.ChromeDriverManager;
import io.github.sridharbandi.AxeRunner;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import java.io.IOException;
import java.net.URISyntaxException;
import java.time.Duration;

/**
 * A sample test to demonstrate
 */
public class Example {

    private WebDriver driver;
    private static AxeRunner axeRunner;

    @BeforeEach
    public void beforeTest() {
        ChromeDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        driver.manage().timeouts().pageLoadTimeout(Duration.ofSeconds(60));
        driver.manage().window().fullscreen();
        axeRunner = new AxeRunner(driver);

    }

    @AfterEach
    public void tearDown() throws IOException {
        axeRunner.execute();
        driver.quit();
    }

    @AfterAll
    public static void generateReport() throws IOException {
        axeRunner.generateHtmlReport();
    }

    @Test
    public void googleTest() {
        driver.get("https://www.google.com/");
    }

    @Test
    public void stockTest() {
        driver.get("https://www.istockphoto.com/");
    }

}

By default, it will check against WCAG2AA and section508 tags. However, you can configure it to tag you want to test with

axeRunner.setTags(AxeTag.WCAG21AA);

Or multiple tags using varargs syntax

axeRunner.setTags(AxeTag.WCAG21A, AxeTag.BEST_PRACTICE);

Each Tag has set of Rules and you can enable/disable particular rule as needed

axeRunner.disableRules("link-name", "aria-allowed-role")
         .enableRules("autocomplete-valid", "region")

HTML Reports will be generated under ./target/java-a11y/axe folder.
