In the software development lifecycle, the testing is playing an important role, which helps to improve the quality, reliability & performance of the system also check that software is not doing what they not supposed to do. There are basically two types of testing in Software Development, Manual and Automation.
Now let’s talk about Automation testing and their importance. Automated accessibility testing is a process where we use a series of scripts to test for the presence or lack of certain conditions in code. These conditions are dictated by the Web Content Accessibility Guidelines, a standard by the W3C that outlines how to make digital experiences accessible.
Accessibility testing which is a subset of usability testing wherein the users under consideration are people with all abilities and disabilities. Since 15 percent of the world population has some kind of disability and among them three percent of those people who have significant disabilities. QA performs the same tests they would for usability testing, but taking into consideration the tools and the software people with disabilities would use.
Now, think about how much time we spend daily using your smartphone or laptop. If your answer is a lot of time, it’s just because we spend an average of seven hours per day using technology. Accessibility testing is how we can make sure that computers and smart devices can be used by everyone, regardless of age and ability. We don’t want anything to miss out on the digital era. It should be a priority for everyone to ensure that every new digital component of our lives can easily be accessible by everyone.
Automatic testing can provide an initial assessment much faster, and give a good idea of the accessibility of the site on a basis of larger scale. Also, as long as all pages of the site are connected, the tester does not have to worry about missing pages. While it is a good idea to double check the finding of the automated testing results, when certain problems reoccur several times, once the validity of the problem is established, the testers can file each occurrence much faster. There are certain issues which automated accessibility testing cannot detect. This depends on the standards and guidelines we are testing for. For example, when we are testing for a specific syntax, like valid HTML, color contrast, or the existence of programmatic table headers, automatic testing tools can provide us with 100 percent accurate results. When we are trying to determine some information is indicated by the use of color only, an automated tool cannot determine it with a good certainty.
There are some advantages of Automated accessibility testing:-
- It is much faster as compared to manual testing.
- Accuracy depends on error and testing standards.
- Guaranteed to check of all link
- Content can be missed, when automated users input is used.
Automated Accessibility testing should always be complemented with manual testing. While automated Accessibility testing is one of the safest methods of testing, we can save a significant amount of time with an automated testing tool, we need to double check the results and rule out other issues. Also, while a testing tool can check for the most standards, it is only a human who can tell if the site is easy to use and navigate for a person who is using any assistive technology.
