5.4 Human Testing

The most thorough approach to ensure mobile application accessibility is to test a mobile application by persons with various disabilities. It is recommended to have the human testing before your mobile application is released. As this testing method requires more time and resources, it is better to first undertake the Visual Review and Manual Testing with Screen Reader to rectify as many accessibility issues as possible, and then adopt human testing at a later project stage to uncover more subtle issues.

Some non-government organisations (NGOs) supporting persons with disabilities can help by providing free or affordable human testing services. Mobile application owners and developers may contact these organisations for assistance.
