Find accessibility issues in layers: lint source code as you edit, inspect the rendered page in a browser, run checks in your usual build and review process, then manually test the affected task. Each layer sees different problems; automated results can guide repairs but cannot prove a site is accessible.
Build accessibility checks into the coding loop
Do not wait until a full-site audit to look for defects. Check work at the level where it is easiest to understand and fix: source while editing, rendered components and pages during development, and the complete user experience during review.
- Lint source as you edit. For React and JSX, eslint-plugin-jsx-a11y statically evaluates JSX patterns and can flag some issues early.
- Inspect the rendered interface. Use a browser evaluation tool on the page or component in its actual rendered state. Source patterns and rendered output are different things, so a clean lint result is not a substitute for this check.
- Run checks in the normal build and review path. Include automated accessibility checks alongside the tests and reviews your project already runs, so findings surface before release rather than in a separate, easy-to-skip process.
- Manually evaluate behavior and context. Try the interaction as a person would: navigate it, operate controls, and judge whether the information and task make sense. Where appropriate, test with assistive technology.
- Repair and recheck. Treat tool results as candidates to investigate. Make a targeted change, then inspect the rendered experience and repeat the relevant manual check.
Choose checks by where they run and what they inspect
W3C/WAI’s evaluation tools directory distinguishes tools by factors such as scope and evaluation method. A component, one page, and a whole site are not the same target; tools may automate checks, support manual evaluation, or simulate experiences. Confirm current supported files and product terms before adopting a specific tool.
| Workflow point | Example | What it contributes | Limit to account for |
|---|---|---|---|
| Source editing | eslint-plugin-jsx-a11y | Static evaluation of JSX patterns. | Its maintainers say it does not evaluate the final rendered HTML; it cannot test the whole experience by itself. |
| IDE or CI/CD | axe DevTools Linter | W3C/WAI lists it for supported-file checks in IDE and CI/CD workflows. | Check the current directory entry for language and framework support, and confirm applicable product terms. |
| Browser | axe DevTools Extension | W3C/WAI lists it as an in-browser accessibility evaluation tool. | A browser scan is one evaluation method, not a guarantee of accessibility. |
| Broader evaluation | W3C/WAI tool-selection guidance and W3C ACT guidance | Help match scope and choose automated, semi-automated, or manual evaluation. | The right combination depends on the project and the testing goal. |
W3C/WAI’s directory lists axe DevTools Linter support for file types including React JavaScript/JSX/TSX, Vue, Angular component HTML, HTML, and Markdown. That support can change, so verify the current directory entry before relying on a particular file type.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
What automation can—and cannot—tell you
Automated checks are useful while coding because they can surface many errors early. They cannot guarantee accessibility, and a passing scan is not a conformance verdict. Static analysis sees code patterns; browser tools see a rendered page; neither alone establishes that the interaction works well for the people who need it.
The eslint-plugin-jsx-a11y maintainers put the source-checking limitation plainly: “Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology.” Use findings to decide what to inspect and repair, not as a substitute for evaluation.

Make manual evaluation part of each change
For a changed component or flow, follow the task a user is meant to complete. Check that controls and instructions are understandable in context, and operate the interface using relevant input methods and assistive technology. The exact manual checks depend on the feature; a form, navigation menu, and dynamic dialog raise different questions.
W3C recognizes automated, semi-automated, and manual testing as distinct approaches. Select methods that cover the target you care about, rather than treating one tool’s coverage as the whole site’s accessibility status.

No. It captures screenshots; use accessibility evaluation tools and manual testing to assess accessibility.
