A fast, feature-rich app means nothing if a portion of your audience can’t use it.

Accessibility testing ensures that your mobile or web application is usable by people with visual, hearing, motor, or cognitive disabilities — and it’s not just a legal requirement. It’s good design. It’s inclusive product thinking. And in many industries, it’s now expected.

At Robust Softech, we test applications against real accessibility standards to ensure they serve all users, not just the average ones.

Why Accessibility Testing Matters

An app that excludes people with disabilities not only limits its audience but also exposes your business to:

• Legal risk (non-compliance with ADA, Section 508, or WCAG)

• Negative brand perception

• Poor SEO and UX scores

• Missed market segments — over 15% of the global population lives with some form of disability

Accessibility testing helps prevent these problems and ensures your app feels polished and usable — even when used in non-standard ways.

What We Test in Accessibility QA

Accessibility testing goes beyond automated audits. Here’s what we cover:

Screen Reader Support

We test with NVDA, VoiceOver, and TalkBack to ensure:

• All UI elements are properly labeled

• Navigation order is logical and consistent

• Complex widgets like modals, tabs, or sliders are announced correctly

• No hidden content is read unintentionally

Keyboard Navigation

Not all users rely on a mouse or touchscreen.

• Can users tab through elements in the correct order?

• Are buttons, forms, and dropdowns fully operable via keyboard only?

• Is focus visible and not lost between steps?

Color Contrast and Visual Clarity

We validate UI elements meet WCAG minimum contrast ratios (4.5:1 for body text, 3:1 for large text), ensuring content is readable in all lighting conditions.

We also test:

• No color-only instructions (e.g., “click the red button”)

• UI clarity with grayscale or low-contrast displays

• Proper use of color-safe palettes for common types of color blindness

ARIA and Semantic Tags

For dynamic components (like dropdowns, carousels, modals), we confirm:

• Proper use of ARIA roles, states, and labels

• Live regions behave correctly when content updates

• Buttons and links use semantic HTML — not just styled divs

Form Accessibility

We verify that forms:

• Have clear, associated labels

• Show accessible validation errors

• Provide hints and instructions via assistive tech

• Allow keyboard input for all elements

Mobile-Specific Accessibility

On mobile platforms, we also test:

• VoiceOver and TalkBack output during interactions

• Zoom and font scaling compatibility

• Gesture alternatives for users who can’t swipe or pinch

• OS accessibility settings like reduce motion or screen inversion

Accessibility Testing Tools We Use

While manual testing is essential, we also use tools to speed up coverage:

• axe DevTools – In-browser accessibility checks

• Wave – Web accessibility scanner

• Lighthouse – Performance + accessibility audit

• NVDA / VoiceOver / TalkBack – Screen reader testing

• Color Oracle / Stark – Simulate color blindness and contrast

• HTML_CodeSniffer – Validate against WCAG 2.1

We use these tools as a baseline — then apply real-world testing to validate usability.

Legal and Compliance Standards

We test against globally recognized accessibility guidelines, including:

• WCAG 2.1 AA – Industry standard for digital accessibility

• ADA (Americans with Disabilities Act) – U.S. law for public-facing platforms

• Section 508 – U.S. federal agency compliance

• EN 301 549 – EU accessibility regulations

Our reports include actionable insights for developers, designers, and compliance teams.

Client Experience:

UK-Based eLearning Platform Reaches More Users

A growing eLearning platform in Galway, UK partnered with Robust Softech after receiving feedback that some users couldn’t navigate lessons with screen readers. They also noticed mobile drop-offs from users with accessibility settings enabled.

The app served a wide demographic — including older learners and visually impaired students — but hadn’t been tested beyond basic QA.

What we delivered:

• Manual screen reader testing on VoiceOver, TalkBack, and NVDA

• Keyboard-only navigation test across all lessons and quizzes

• Identified missing aria-labels, unlabeled form elements, and poor focus indicators

• Conducted contrast testing for text, buttons, and background

• Provided a prioritized report with fixes categorized by severity

Results:

• Accessibility score improved from 58% to 97% using Lighthouse

• Student satisfaction surveys reflected higher ease-of-use for screen reader users

• Mobile accessibility-related drop-offs reduced by 40% in 6 weeks

• Platform was successfully submitted for government-funded accessibility grants in UK

By fixing hidden barriers, the platform reached more learners and improved outcomes for all users — not just those flagged in accessibility reports.

Client Success Story

How Robust Softech Builds for Accessibility from Day One

We embed accessibility into the QA lifecycle with:

• Full audits aligned with WCAG 2.1

• Manual testing by trained QA specialists

• Real-user simulations (screen readers, keyboard-only, zoomed UI)

• Design feedback to fix issues before they reach production

• Compliance-ready reports for internal and legal use

We believe accessibility is not a fix — it’s a responsibility. And we help your team get it right without slowing down your product roadmap.
