Execute Your Automation Tests with Accessibility Tool

This document walks you through the process of evaluating the accessibility of your website through the execution of automated tests using LambdaTest's Accessibility Tool.

It is supported for Chrome version 88 and later only.

Prerequisites

• Your LambdaTest Username and Access key
• Setup your local machine as per your testing framework.

Step-by-Step Guide to Trigger Your Test

Step 1: Setup Your Test Suite

You can use your own project to configure and test it. For demo purposes, we are using the sample repository.

sample repo

Download or Clone the code sample from the LambdaTest GitHub repository to run your tests.

View on GitHub

If you are using your own project, make sure you update the Hub endpoint in your tests file.

By setting up the Hub endpoint, you establish the communication channel between your tests and the browser nodes, enabling effective test distribution and execution.

Configure the desired capabilities based on your test requirements. For example:

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("browserName", "chrome");
capabilities.setCapability("version", "70.0");
capabilities.setCapability("platform", "win10"); # If this cap isn't specified, it will just get the any available one
capabilities.setCapability("build", "LambdaTestSampleApp");
capabilities.setCapability("name", "LambdaTestJavaSample");

You can generate capabilities for your test requirements with the help of our inbuilt 🔗 Capabilities Generator Tool.

Step 2: Establish User Authentication

Now, you need to export your environment variables LT_USERNAME and LT_ACCESS_KEY that are available in the LambdaTest Profile page.

Run the below mentioned commands in your terminal to setup the CLI and the environment variables.

Linux / MacOS

export LT_USERNAME="undefined"
export LT_ACCESS_KEY="undefined"

Windows

set LT_USERNAME="undefined"
set LT_ACCESS_KEY="undefined"

Step 3: Configure the Necessary Capabilities

To enable the accessibility testing within your automated test suite, set the accessibility: true in your configuration file. You can also define other settings capabilities as described below.

capabilities: [{
  accessibility : true,                 // Enable accessibility testing
  accessibility.wcagVersion: 'wcag21a', // Specify WCAG version (e.g., WCAG 2.1 Level A)
  accessibility.bestPractice: false,    // Exclude best practice issues from results
  accessibility.needsReview: true       // Include issues that need review
}]

Step 4: Execute and Monitor your Test

Now execute your tests and visit the Automation Dashboard. Click on the Accessibility tab and check the report generated.
