How to Achieve Automated Accessibility Testing
Testing accessibility is important for web and mobile applications. Here, we break down why automated accessibility testing is important. And we share how to automate accessibility testing with the right tools.
What Is Automated Accessibility Testing?
Accessibility testing is a type of testing done to ensure that your apps are usable by as many people as possible. Automated accessibility testing helps expedite your release cycle and identify issues early.
Accessibility testing is about making your app’s content and services usable by people with disabilities from various types (vision, hearing, etc.). It’s also about ensuring that accessibility information can be discerned and the user interface operated. Automation helps you do this faster and with fewer defects.
In many cases, accessibility testing is done too late in the software development cycle due to lack of automation process, or lower priority.
Accessibility is as important as any other functional, performance, API, or any other testing that is being created and executed. To make accessibility testing more efficient and sustainable, you need to shift it left. Automation is critical to this.
Can Accessibility Testing Be Automated?
Accessibility testing can — and should — be automated.
Most accessibility tests today are done manually — or not at all. Accessibility testing is not part of the lifecycle, and it usually isn’t automated. But it should be.
Accessibility needs to be embedded right from the beginning of development. Like other types of testing, by shifting left, you can identify accessibility defects when they’re less expensive to fix. Once an accessibility defect is in production, the cost to fix it can be 100x higher than when it’s addressed in design.
Why Automated Accessibility Testing Is Important
Automated accessibility testing is important to ensure user satisfaction, comply with market software standards like WCAG, and avoid business loss. This is especially important, as the World Bank estimates that 15% of people have a disability.
Accessibility testing ensures that everyone can use your web or mobile app. There’s also legislation around accessibility for people with disabilities. Automated accessibility testing helps you comply with this legislation.
This helps you reduce the risk of accessibility defects — and potential lawsuits.
How to Automate Accessibility Testing
Here’s how to automate accessibility testing.
1. Make Accessibility a Focus Earlier — During Design
Accessibility needs to be a focus throughout your Agile process, starting with design.
Design plays an instrumental role in your testing. It provides the meaning for what you will be testing. And much of accessibility is in the meaning.
Your designers think about the components of their user interface. For example, they think about what a button with a little pencil inside of it does. That is, it pops up the Edit dialog box. The designers communicate what that button is going to do to the rest of the development team. It can then be used by developers to implement the functionality correctly. And you can write automated tests to ensure that the button attribute is what it should be.
This is an important step to automating accessibility testing.
2. Leverage Accessibility Testing Tools
It’s also important to leverage accessibility testing tools.
Accessibility testing can seem insurmountable. That’s because a lot of organizations approach accessibility testing from a manual perspective. With the right tools, you can approach it from an automated perspective.
First, you’ll want to consider generic accessibility testing libraries. They’re available for different platforms, such as HTML, Android, and iOS. They give you a set of acceptance tests for accessibility. We typically find that up 50% of accessibility issues can be found by leveraging these libraries.
Another accessibility testing tool you can leverage is interactive intelligent guided testing. This capability is embedded in a browser extension. For example, it allows developers to test for buttons and links. This ensures that the accessible names associated with buttons and links are accurate.
This is the type of information communicated from designers to developers and testers. You can use this information to write an automated test.
3. Create Automated Regression Tests For Accessibility
Regression tests are great candidates for automated accessibility testing. You can use the methodology above to create automated regression tests for accessibility. This can help you keep the costs of testing down. And, at the same time, you can eliminate most of your manual testing out of the development process.
