Accessibility Testing Workflow

A well-defined workflow is essential for systematically and efficiently testing accessibility, documenting problems in a way that is understandable, and continuously implementing improvements. This chapter shows typical phases and roles in a well-thought-out test workflow.

Preparation and goal definition

  • Define relevant standards (e.g. WCAG 2.2 AA)
  • Define the scope of the test (e.g. homepage, central functions)
  • Clarify roles and responsibilities (e.g. QA, UX, development)

Preliminary analysis (optional)

  • First review using automated tools (e.g. WAVE, Axe)
  • Recognition of obvious barriers
  • Comparison with existing knowledge or previous versions

Detailed test execution

  • Manual tests (see chapter 3.2.1)
  • Screenreader test (see chapter 3.2.2)
  • Combination with automated tests for completeness

Documentation and evaluation

  • Document all found barriers including WCAG reference (see chapter 3.3)
  • Assessment of relevance for user groups (critical, notice, etc.)
  • Recommendation for fixing or passing on to responsible teams

Communication and improvement

  • Transfer of results to development / design
  • Discussion of unclear points with experts
  • Definition of deadlines and priorities

Re-test / regression testing

  • Check if fixed barriers have actually been resolved
  • Validation by repeating central test steps
  • Comparison with previous version or reference status

Conclusion and reporting

  • Summary of results (e.g. in gooda11y or as PDF report)
  • Optional: evaluation for training or governance
  • Derivation of lessons learned for future projects

Recommendations for a smooth process:

  • Integrate tests early into the project (“Shift Left”)
  • Regular team discussion about process and results
  • Use tool-supported documentation and progress control
  • Plan testing with real user groups, where possible

A well-defined workflow lays the foundation for efficient accessibility testing that not only meets legal requirements, but also improves user experience and the quality of digital offers.
