Starting an Accessibility Scan with Web Scanner

Purpose of Accessibility Scan

Accessibility scans ensure that websites are inclusive and usable for users with disabilities by identifying WCAG violations such as missing alt text, insufficient contrast, inaccessible form elements, and more.

These scans help:

• Meet legal compliance (ADA, WCAG 2.0/2.1)
• Improve usability for all users
• Reduce the burden of manual audits

Step 2 (If Accessibility Scan is Selected)

Once you select Accessibility in Step 1 of the scan wizard, the following configuration UI is displayed:

Default Selections:

• WCAG Version: WCAG 2.1 AA
• Review Issues “ON“: Enables manual verification for accuracy.
• Best Practices Issues “ON“: Ensures user experience enhancement issues are accounted for.

Advanced Options (Accessibility Scan)

Local Testing Setup

• Activates LambdaTest Tunnel to scan localhost or staging environments.

Login Configurations

• Reuse or create new login setups.
• Supports:
  • Basic Authentication (username/password)
  • Form-based login (via CSS selectors)

More options:

• Review Issues (Needs Review): Enable this to include issues that require human verification (e.g., aria-label usage). These may not be violations but need manual inspection.
• Best Practices Issues: Enable this to detect suggestions that improve UX but do not violate accessibility rules. Examples include adding landmark roles or enhancing keyboard support.
