Accessibility in web environments means that tools and technologies are developed and modeled for people with disabilities to be able to use them. It is also necessary to ensure that the target audience can understand, navigate, interact, and perceive the proposed environment. Accessibility on the web includes several groups of disabilities such as: auditory, visual, neurological, cognitive, etc. Over time, numerous surveys show ways to conduct accessibility tests. However, its authors do not attempt to evaluate accessibility with an emphasis on deaf users. Therefore, there is a lack of resources that provide acceptable accessibility tests for deaf people. Therefore, this dissertation aims to identify accessibility requirements for deaf people and address automation approaches for accessibility testing. For this, a study was carried out on guidelines and accessibility standards for deaf people. In the development of this study, a prototype of a web application called the interpreter center was developed. This application interacts with deaf users through videos in Sign Language developed in partnership with the Language department of the Federal University of Goias. The results of this work are related to the definition of accessibility requirements based on the accessibility guidelines identified through the literature review. The accessibility requirements were used to elaborate 2 research questions to carry out the accessibility tests. Static software analysis was the main approach to perform the accessibility test. The 2 approaches to accessibility testing in this work are: i) Metadata testing; ii) Test by descriptive statistical analysis. The contributions of this dissertation involve assessing accessibility for deaf users in web environments. To automate the evaluation through tooling support, a tool called Web Accessibility Evaluation Testing was developed to address accessibility on web pages. This assessment is based on accessibility requirements where, through tooling support, warnings display the success or failure of accessibility on a web page. We conclude that the approaches presented for assessing accessibility are effective for testing accessibility for deaf people in web environments.
