Web Accessibility testing

Explore the concept of accessibility as the design of usable products for people with disabilities. See how keyboard, ramp, screen readers, and step by step forms improve universal digital usability.

Explore why accessibility matters for inclusivity, legal compliance, and business value, and learn to apply user experience basics, empathy, and manual and automated testing for Web Content Accessibility Guidelines (WCAG).

Explore how visual, hearing, motor, and cognitive disabilities affect web accessibility, and learn to test with screen readers, captions, keyboard navigation, color contrast, and simple layouts.

Explore wcag 2.0 and 2.1, levels a, aa, and aaa, and the four principles: perceivable, operable, understandable, robust.

Learn how assistive technologies like screen readers (JAWS, NVDA, Narrator, VoiceOver, TalkBack) and refreshable Braille enable keyboard-only access, and why keyboard functionality and HTML structure matter in accessibility testing.

Explore the HTML structure and distinguish semantic from non-semantic elements, understanding landmarks for screen readers, roles and states, and how headers, nav, main, sections, and interactive elements support accessible navigation.

Explore how HTML landmarks create a semantic layout with header, main, sidebar, and footer, and learn to test screen reader navigation using Nvda shortcuts.

Learn how semantic html elements support accessibility by testing heading order, inspecting code to ensure a single h1 and correct h1 to h6 sequence for screen readers.

Explore semantic html elements and nvda screen reader behavior for headings, lists, and landmarks, contrasting with non-semantic markup to improve accessibility testing.

Explore semantic static HTML elements and how proper ul and ol list structures boost accessibility for screen readers.

Learn the HTML table structure with table, tr, th, and td, featuring four columns, and how screen readers interpret it, including image alt text and headings, lists, and tables.

Understand how screen readers announce well-structured HTML tables, including rows, columns, headers, and data linked to headers, and how images with alt text are described.

Explore HTML interactive elements such as links, buttons, and form controls, and learn how keyboard navigation, focus indicators, and screen readers like NVDA convey their status for accessible testing.

Use axe devtools to automate accessibility testing on a website, scan pages for issues, and review severity levels from critical to minor, with guided fixes and reporting.

Explore how Wave validates accessibility, reveals color contrast issues, heading order problems, and attributes, and learn to interpret reports for automated and manual testing.

Introduce manual testing for web accessibility, focusing on keyboard operability via tab navigation and activation with enter or spacebar. Ensure screen reader compatibility and focus indicators.

Learn how accessibility testing begins in design, focusing on responsiveness and readability, plus color contrast, target size, meaningful content, and complexity to ensure readable, usable web experiences.

Improve web accessibility by checking readability, reading order, and typography, and apply WCAG 2.1 1.4.12 spacing and color contrast tests with a color contrast analyzer.

Ensure target size of 44 by 44 pixels for icons and buttons to be easily clickable on small screens and dexterity issues, use meaningful content and provide pause for motion.

As an accessibility tester, log image issues by documenting alternative text for each image, verify 15 images, and ensure alt text conveys meaning or remains empty for decorative images.

Initiate web accessibility testing by running automation tools on a defined scope, identify critical issues, and document labeled fixes with descriptive notes and screenshots.

Test keyboard accessibility by tabbing through focusable elements, verify focus indicators and color contrast, and check focus management when modals appear to ensure all operations are reachable.

Use automation tools to identify accessibility issues, then conduct manual keyboard testing to verify focus indicators and focusable elements in the navigation bar, documenting findings with screenshots and issue reports.

Test a real website with the Nvda screen reader to verify content and form elements, capture issues with screenshots, and report actual versus expected results.

Test common accessibility issues in web pages, including correct tab order, proper heading order, meaningful link text, informative alt text, and properly labeled forms announced by screen readers.

Explore aria attributes for accessible rich internet applications, defining semantic roles, name, value, and state for non-semantic elements and custom widgets, and learn when to use role and descriptive labeling.

Explore aria-label and other aria attributes using the Mozilla developer site, see how invisible labels provide screen reader access, override visible text, and inform users about links opening in tabs.

Learn how aria-labelledby and aria-describedby associate labels and descriptions with input fields, enabling screen readers to announce both the label and description for accessible forms.

Explore how aria attributes convey state for custom widgets, using aria-expanded and aria-checked with roles like combo box, to support screen readers and keyboard navigation.

Discover how role attributes and ARIA roles change non-semantic elements into accessible links, buttons, and headings, using tab index and screen reader behavior to illustrate focus and presentation.

Mastering focus management for web accessibility by testing focus trapping in modal dialogs, ensuring keyboard users tab through elements and screen readers announce the correct focus changes and alerts.

Create a final accessibility report documenting WCAG conformance levels, severity, actual vs expected results, and QA status, including name, URLs, date, author, and testing method.
