How Do You Test SaaS Accessibility? A Step-by-Step Workflow

Effective SaaS accessibility testing combines a clear project scope with both automated and manual audits, covering all user flows, platforms, and interactive elements.

Stepwise Accessibility Testing Process

1. Scope Your Testing
   • Map out all digital interfaces: web, mobile, dashboards, and especially Single Page Applications (SPA).
   • Identify priority user flows (login, registration, transactions, reports).
2. Run Automated Accessibility Checks
   • Use leading audit tools to quickly detect code-level issues (see tool comparison below).
   • Focus on critical paths and high-traffic pages.
3. Conduct Manual & User-Based Testing
   • Test with screen readers (JAWS, NVDA, VoiceOver).
   • Verify full keyboard navigation.
   • Check color contrast and dynamic content accessibility.
   • Include real users with disabilities where possible.
4. Special Considerations
   • Test SPA-specific elements: dynamic loading, ARIA roles, focus management.
   • Address unique issues for mobile SaaS (touch targets, zoom, voice input).
5. Collate Findings & Prioritize Remediation
   • Grade issues by severity and user impact.
   • Prepare actionable remediation handover for dev/UX teams.
6. Retest and Integrate Into CI/CD
   • Confirm fixes through regression testing.
   • Embed automated checks in your release process for continuous compliance.

Remember: “Accessible by design”—building accessibility early—always outperforms last-minute audits.

   • Critical: Blocks user (e.g., no keyboard access to main flows)
   • Major: Impairs interaction but has workarounds
   • Minor: Minor annoyances, non-core impact
2. Common SaaS Accessibility Errors
   • Modal dialogs that trap keyboard focus
   • Dynamic content updates not announced to screen readers
   • Inaccessible authentication (e.g., inaccessible 2FA flows)
   • Insufficient contrast or missing labels in dashboards
3. Best Practices for Fixes
   • Follow WCAG 2.2 criteria directly in code changes.
   • Retest after each release; automate regression checks.
   • Pair development fixes with design system updates.
4. Training and Culture
   • Educate devs and designers on accessibility patterns.
   • Build “shift-left” accessibility into pull requests, code reviews, and QA specs.
5. CI/CD Integration
   • Include automated accessibility testing at every build.
   • Track fixes and documentation in version control.

   • Get the template from ITI
2. Identify Applicable Standards
   • Confirm which WCAG/EN 301 549 criteria your SaaS addresses.
3. Complete Each Section
   • State “Supports,” “Partially Supports,” or “Does Not Support” for each criteria; include notes on gaps/remediation plans.
4. Review with Legal and QA Teams
   • Ensure claims are accurate and risks validated.
5. Version and Share
   • Update with each release or new audit. Provide to procurement/RFP contacts as required.

Procurement & RFP Accessibility Checklist

• Has a current, accurate VPAT/ACR been provided?
• Are gaps or exceptions clearly documented?
• Is evidence of remediation or audit history available?
• Is the document signed or attested by an authorized representative?

Best practice: Use version control and conduct periodic legal reviews to keep documentation current.
