1. What is Accessibility Testing?
In software testing, accessibility testing is frequently done to ensure that the programme is usable by people with disabilities and that the developer will modify it so that it is accessible to all users, including those who are physically challenged and ordinary users (colour blindness, learning disabilities, and so on).
This section will cover accessibility testing, including what it entails, why it is done, what it is used for, and the tools used in it.
2. Need for Accessibility Testing
It’s crucial to provide product advances to those with specific needs. They call for the incorporation of specialised technology in goods. These technologies include voice recognition software, screen readers, screen magnifiers, and specialised keyboards for working and communicating.
However, several cutting-edge goods, programmes, and websites are neither user-friendly nor open to everyone. The accessibility test is designed for average users and individuals with various impairments. The goal of an accessibility test is to ensure that an application can be used by those with various disabilities, including visual, auditory, physical, cognitive, linguistic, learning, and neurological impairments.
3. Goal of Accessibility Testing:
The following are the goals of accessibility testing:
- To promote markets for individuals with disabilities.
- Should adhere to accessibility laws.
- To prevent possible lawsuits.
4. How may your resource be made more accessible
You should go through this checklist to ensure that your website is welcoming, uncomplicated, and open to all users:
4.1 Selectivity
By dividing the primary and supporting elements, it is vital to make it as easy as possible for the reader to understand the text. By expanding the text size to 200%, for instance, you may make the article more straightforward to read.
Additionally, it is worthwhile to provide the user with the option to silence the sound on the current page if there are banners with voices acting on the page.
4.2 Media Content
People with hearing difficulties will grasp the topic far more easily if it is presented in sign language.
4.3 Adaptability
When content is presented in various ways, its significance shouldn’t be lost. It should be kept in mind that occasionally altering the order or layout of the content might affect the meaning of the information. As a result, it’s crucial to decide in advance what sequence the information blocks must be presented in.
4.4 Readability
Decoding acronyms and employing a technology that lets you hear a word’s pronunciation when it is crucial to comprehending its meaning are two examples of how to do this.
5. How are accessibility tests conducted?
There are two approaches to conducting accessibility testing, and they are as follows:
- Manual v/s Automated.
5.1 Manual Method
Let’s look at various cases where we manually test the application’s accessibility:
- We may utilise the huge font size and check the availability by changing the font size.
- We may draw attention to the website’s content using a high contrast setting. When we switch to the high contrast option in our browsers, the website’s content is automatically highlighted and changed to white or yellow while the backdrop remains black.
iii. While zooming out, we may assess how readable the image is.
5.2 Automation Method
In general, different testing techniques employ the automation process. Several technologies for doing accessibility testing are included in the automated testing process.
Text alternatives are available for every non-text item. Through alternate channels like voice, people with disabilities can access information that is not in the text.
6. Tools are used for Accessibility Testing
We have discussed below tools used for the accessibility testing.
6.1 Web Accessibility Checker
This tool is well-known for offering the simplest ways to carry out accessibility checks on the ASP.NET web applications. This tool meets several international accessibility standards and is easily customisable.
6.2 Wave
It is a web accessibility tool that WEBAIM has made available. It is an open-source programme that automatically evaluates the website’s accessibility at various stages. It is a collection of evaluation tools that make sure authors make their work easier to access for people with physical disabilities.
6.3 AChecker
This open-source programme is intended for assessing online accessibility. By uploading an HTML file or inputting a URL, one may quickly assess the accessibility of a website using this tool. Additionally, this tool offers several accessibility standards from which to pick, including the Stanca Act, BITV 1.0, WCAG 2.0, Section 508, and HTML Validator.
6.4 TAW
The programme enables you to examine a website per W3C web accessibility guidelines and displays any accessibility issues. The accessibility of our website is determined using an online tool. Additional classifications for the web accessibility test issue include Priority 1, Priority 2, and Priority 3. The WCAG 1.0 subsets will also be available through this tool.
6.5 Tenon
Because of its adaptability, precision, and high-quality outcomes, this tool is well regarded as an online accessibility tool. The tool integrates with the current toolkit and makes use of APIs. The programme efficiently generates evaluation reports in HTML, CSV, XML, and JSON.
6.6 Web Accessibility Toolbar
Web page designers may take advantage of valuable capabilities in WAT, an extension of Internet Explorer or Opera. The GreyScale function, which aids in locating areas of low contrast in the design, is one of the most excellent features.
7. How TestDel can assist you with accessibility testing?
We test usability, efficiency, maintainability & portability. To test the readiness of a system as per non-functional parameters which are never addressed by functional testing.
- Scalability
TestDel scales, resources and devices to meet client expectations. Our test lab has over 250 mobile, tablets, desktop systems.
- On Demand
Hire us for the days that you like. From limited single tester contributions to comprehensive ongoing QA programmes.
8. Conclusion
Ultimately, we can state that accessibility testing refers to evaluating software or applications so any user can use them. Because the test engineer’s goal while testing an application is to determine whether or not all the strategies are satisfied, the test engineer might undertake accessibility testing from each user’s perspective. All users should have no trouble using that program.
Every company places a high priority on accessibility because many disabled and/or elderly individuals rely on their digital products. TestDel has successfully evaluated a lot of websites for WCAG compliance over the past few years.
In general, TestDel has assisted a large number of clients during the past six years. We recognise that when it comes to websites and apps, reputations of trust and dependability are crucial in any industry.
