Accessibility Testing can be defined as a type
of Software Testing performed to ensure that the application or websites being
tested is usable by people with disabilities like hearing, color blindness,
old age and other specially-abled people. It is a subset of Usability Testing.
Before evaluating any Accessibility Testing tool we should be aware of what are the features needed to be incorporate in a website in order to make it accessible to everyone.
Accessibility features are designed to help people with disabilities so that they can use technology more easily.
For example, a text-to-speech feature may read text out loud for people with limited vision, while a speech-recognition feature allows users with limited mobility to control the computer with their voice.

What Are Accessibility Features?
Before evaluating any Accessibility Testing tool we should be aware of what are the features needed to be incorporate in a website in order to make it accessible to everyone.
Accessibility features are designed to help people with disabilities so that they can use technology more easily.
For example, a text-to-speech feature may read text out loud for people with limited vision, while a speech-recognition feature allows users with limited mobility to control the computer with their voice.
Common Accessibility Features
1. Features for blind or low-vision
computer users: Features such as text-to-speech allow users to hear
what's on the screen instead of reading it. Other features, like high-contrast
themes and enlarged cursors, make it easier for users with limited vision to
see the screen.
2. Features for deaf or low-hearing
computer users: Closed-captioning helps to convey audio information to
deaf users in visual form. Mono audio systems transmit right and left audio
signals through both earbuds and headphones so users with limited hearing in
one ear will not miss part of what they are listening to.
3. Features
for limited-mobility computer users: Keyboard shortcuts are convenient
for many people, but they are especially helpful to those with difficulty
physically manipulating a mouse. For users who have difficulty pressing several
keys at once, sticky keys allow them to press keys one at a time to activate a
shortcut.In order to understand the accessibility more, Let’s take an example of windows Operating system which provides the wide verity of options to make it accessible to every user across the globe.
