Web accessibility testing for Singapore government e-services

The paper proposes a customized automated accessibility testing tool built on existing open source tools that makes upholding web accessibility standards less daunting and overwhelming for developers working on Singapore government e-services. We incorporate findings from contextual inquiry (N = 8) on government e-service use by persons with disabilities (PWDs) in Singapore to help software development teams identify and prioritise accessibility test findings within the agile development cycle. Our tool incorporates a customised accessibility audit tool with rule set prioritised from the contextual inquiry, and built as part of a software package that can be rapidly deployed on continuous integration / continuous delivery (CI/CD) platforms to scale up the adoption and accessibility testing. The goal of our tool is to deliver a usable output for developers and product managers that is streamlined, targeted, and integrated into existing workflows.
