  2. Conducted a thorough audit of a mobile app to ensure WCAG 2.1 compliance resulting in a 10% increase in accessibility score

2. Can you describe a recent project where you tested accessibility and determined what changes needed to be made?

During my previous employment at XYZ Corp, I worked on a project to improve accessibility for a major e-commerce website. My first step was to conduct an accessibility audit to identify areas that needed improvement. The audit revealed that certain images lacked alt attributes, which prevented screen reader users from understanding the content. Additionally, there were several links that were not clearly labeled, which caused confusion for visually impaired users.

Based on these findings, I worked closely with the development team to implement changes. We added alt attributes to all images throughout the website, giving users with visual impairments a better understanding of the content. We also re-labeled all unclear links to make them more explicit and intuitive.

After implementing these changes, we ran several tests to ensure that the website was now more accessible across all devices and browsers. Our efforts resulted in a significant improvement in the accessibility score, going from 45% to 90%. We also received positive feedback from users, including a 20% increase in user retention rate among disabled users.

3. How do you ensure accessibility testing occurs throughout the entire software development cycle?

At my previous company, I worked with the development team to implement an accessibility checklist that would be incorporated into the software development life cycle (SDLC). This checklist included items such as ensuring sufficient color contrast and labeling all form elements, among other criteria that would ensure compliance with accessibility standards.

  1. During the requirements gathering phase, I would consult with the product owner to confirm that accessibility requirements were being included in the user story.
  2. Once development began, I conducted manual testing to verify that the product was following the checklist.
  3. In addition, we incorporated automated accessibility testing using tools such as axe-core and WCAG Contrast Checker into our continuous integration and delivery (CI/CD) pipelines to catch any accessibility errors early in the development process.
  4. During the testing phase, I would conduct manual and automated testing, as well as work with our QA team to incorporate accessibility testing into their testing plan.
  5. Finally, before releasing the product, I would conduct one final comprehensive accessibility audit to ensure that there were no outstanding issues.

Through this process, we were able to reduce the number of accessibility issues that made it into production by 70%. This not only ensured compliance with accessibility standards but also improved the overall user experience for all users, regardless of ability.

4. What techniques do you use to identify accessibility issues with dynamic content?

One technique I use to identify accessibility issues with dynamic content is to conduct automated testing using tools such as aXe or WAVE. These tools can quickly scan a webpage and detect accessibility issues, including those related to dynamic content. Another technique I use is manual testing with keyboard-only navigation. I navigate through the page using only the keyboard, making sure all dynamic content is accessible and easy to use with different keyboard shortcuts. I also check for proper focus management and make sure that users are able to easily interact with the dynamic content. In addition to automated and manual testing, I ensure the website meets the Web Content Accessibility Guidelines (WCAG) by conducting thorough accessibility audits. These audits examine the site's accessibility issues, including those related to dynamic content, and provide actionable insights to resolve any issues found. One example of success in applying these techniques was during an accessibility audit for a financial services website. Using automated testing, manual testing, and WCAG guidelines, we found and fixed several accessibility issues related to dynamic content. As a result of our efforts, the website's accessibility score increased by 20% and received positive feedback from users with disabilities. By combining automated testing, manual testing, and WCAG guidelines, I can effectively identify and resolve accessibility issues related to dynamic content. The result is a more accessible website that provides a better experience for all users, regardless of their abilities.

5. How do you prioritize accessibility issues with other bugs and issues?

As a QA tester with experience in accessibility testing, I understand the importance of equal access to digital content. Therefore, I prioritize accessibility issues equally with other major bugs and issues.

  1. First, I analyze the severity and impact of the bug on the user experience. If the bug is creating a barrier for users with disabilities, it immediately becomes a top priority.
  2. Secondly, I look at the number of users affected by the issue. If the bug is affecting a large number of users, it requires immediate attention.
  3. Thirdly, I consider the cost and time required to fix the bug. However, I would never compromise on accessibility in order to save time or money. I firmly believe that equal access is a human right and should be ingrained in every aspect of product development.

To give an example, in my previous job, we conducted accessibility testing on a website and identified a bug that prevented screen readers from reading the text on a particular page. We immediately flagged it as a high-priority bug, as it impacted a significant number of users with visual impairments. Our development team fixed the bug within the same week, resulting in a 30% increase in user engagement and positive feedback from users with disabilities.

In conclusion, ensuring equal access is of utmost importance when it comes to product development. I believe that every bug or issue should be addressed with an equal amount of diligence, regardless of its nature. Prioritizing one aspect over the other can have a negative impact on user experience.
