It is a method that significantly bolsters the accessibility of digital platforms by automating the detection and correction of visual inconsistencies.

This approach ensures compliance with legal standards and promotes an inclusive digital environment, making technology accessible and usable for diverse users.

Standards like the Web Content Accessibility Guidelines (WCAG), which work to improve the usability of digital content for people with a range of disabilities, including those affecting speech, vision, cerebral function, neurological system, and physical mobility, serve as a guide for this commitment.

To foster an inclusive environment, digital accessibility is vital. In addition to mitigating potential legal consequences, the primary objective is to guarantee equitable access to information and services for all individuals. This is critical as the internet gets increasingly ingrained in all facets of life, including work, education, healthcare, and social interaction.

What is Visual Testing?

The automated identification and evaluation of visual elements on a website or application to make sure they adhere to predetermined standards is known as visual testing. This means looking at the font sizes, button sizes, color contrast, and overall layout. This aims to identify visual elements that may pose obstacles to accessibility.

Key Components of Visual Testing

Here are all the major key components of visual testing –

  • Color Contrast Analysis: Text and background colors contrast well enough for people who are color blind to read them.
  • Font and Text Size Adjustability: Regarding font and text size, ensuring that individuals with vision impairments can adjust and read the content is crucial.
  • Visibility of Interactive Elements: Clear and user-friendly form elements, buttons, and links are guaranteed by interactive element visibility.
  • Testing Responsive Design: Verify the content is readable and accessible across various screens and devices by testing your responsive design.
