Why Accessibility testing in Testing Fundamentals? - Purpose & Use Cases

The Big Idea

What if your website is invisible to some users without proper testing?

The Scenario

Imagine you build a website with buttons, links, and forms. You only check if it looks good and works with a mouse.

The Problem

People who use keyboards, screen readers, or have color blindness might find your site hard or impossible to use. You miss these problems if you don't test for accessibility.

The Solution

Accessibility testing helps you find and fix issues so everyone, including people with disabilities, can use your website easily and comfortably.

Before vs After

✗ Before

Click here (no keyboard focus, no labels)

<button>Submit</button>

✓ After

<button aria-label="Submit form">Submit</button>

What It Enables

It enables your website to be usable by all people, improving reach, user satisfaction, and legal compliance.

Real Life Example

A blind user relies on a screen reader to navigate your site. Accessibility testing ensures your buttons and links have clear labels and keyboard focus so they can use your site smoothly.

Key Takeaways

Manual testing misses many accessibility problems.

Accessibility testing finds issues for users with disabilities.

Fixing these issues makes your site better for everyone.
