    1. Web Content Accessibility Guidelines (WCAG) best practices

    In order to enhance the productivity of an application, testers strive hard and always learn the latest concepts. In various testing methods, accessibility testing has huge significance because it deals with the usability of an application.

    Previously, when testers obtain the task of accessibility testing, they get worried. But now, with the evolution of technology, accessibility testing is their preferred choice.

    Also, being an experienced accessibility testing company we will share some best accessibility testing tools. Further, with a team of experts, we are actively offering premium Web accessibility testing services in India & USA.

    W3C (World Wide Web Consortium) has made WCAG (Web Content Accessibility Guidelines). Here we will also learn about WCAG best practices that further improve your skill and quality of the applications.

    Additionally, the guidelines should be on priority in your website accessibility testing checklist. Further, being a quality tester, one should always be focused on the usability of an application because the application has no value if it is not in use.

    As per the analysis, approximately 67% of the applications are discarded because users don’t find them convenient. It happens because of poor accessibility testing, and you should not make this happen with your product.

    Hence always track the performance, appeal, and usability of your application by implementing the best web and mobile app accessibility testing tools.

    Web Content Accessibility Guidelines (WCAG) best practices

    If you are strengthening your accessibility testing skill, you must have knowledge about WCAG best practices. The concept illustrates how to make your web application accessible to audiences having disabilities.

    As we know, the businessmen made an application for the public. And if it justifies its role by offering accessibility to the diverse range of audiences having issues of sight, cognitive disability, hearing, and motion then you can consider your application successful.

    The ultimate aim of  web content accessibility guidelines (WCAG) is to offer equal access to people either with or without disabilities. Elements that need your attention for accessibility testing are:

    • Perceivable
    • Operability
    • Robust
    • Understandable

    Do you know 508 Compliance Testing?

    Federal agencies, private organizations, and institutions that receive federal funds through Assistive Technology Act, are bound to follow this law set standard.

    508 Compliance Testing aims to develop applications (any form of electronics, software mobile) that must be accessible to all individuals including the disabled.

    Further, the policy covers hardware, software applications, websites, printers, multimedia, mobile applications, systems, and networks. Whoever comes in this domain, must follow the policy.

    Organizations fail to deliver the required expectation, they come at the risk of prosecution under federal law and further, they lose potential customers having disabilities.

    Follow the shared approach to increase the usability of your web or mobile application.

    Always make sure, the product should make sense, independent of the way it is perceived.

    Making a product for a normal user base is fine, but you should always keep in mind the people having disabilities. For those who have no or low eye-sight, implement the text to speech feature so that they can also understand your business idea. Similarly, cover the other cases as well.

    Ensure that the content is easy to read and understand

    Another aspect that comes under web accessibility best practices, content should be properly visible, clear, and relatable. Sometimes the old-age group cannot read the text because of poor visibility or alignment. The font size should be well optimized, and during testing, the testers must keep this point in mind.

    Your product should have effortless navigation.

    Navigation is something, that gives direction to your audiences, and if it does not execute properly, they will get lost. And it is not at all acceptable. Hence by using the best accessibility testing tools, you can ensure smooth navigation in an application.

    Users should have enough time to interact.

    Suppose you have developed your website using some time-sensitive elements that fade in or fade out at certain intervals. Likewise, if you have implemented a banner that slides, you need to make sure the content of these elements should be visible to users for the required period of time. If it runs too fast, users get confused, and they leave the platform immediately.
