Detecting keyboard accessibility issues in web applications

A system for detecting and/or localizing a keyboard accessibility failure (KAF) comprising:

• a control system comprising one or more processors and at least one non-transitory memory;
• and
• a keyboard;
• wherein the control system is configured to execute the machine executable code stored in the non-transitory memory to cause the control system to:
• read a document object model of a web page;
• generate a keyboard navigation flow model from the document object model of the web page based on interactions of a user with the web page, wherein the keyboard navigation flow model includes states representing user interfaces displayed by the web page, nodes representing keyboard inputs in the states, and edges representing transitions that occur in the web page between the nodes;
• detect one or more KAFs based on an analysis of the keyboard navigation flow model;
• and
• produce a report of the detected one or more KAFs on the web page.

A non-transitory machine readable medium having stored thereon instructions for performing a method comprising machine executable code which when executed by at least one machine, causes the machine to:

• read a document object model of a web page;
• generate a keyboard navigation flow model from the document object model of the web page based on interactions of a user with the web page, wherein the model includes states representing user interfaces displayed by the web page, nodes representing keyboard inputs in the states, and edges representing transitions that occur in the web page between the nodes;
• detect one or more keyboard accessibility failures (KAF)s based on an analysis of the keyboard navigation flow model;
• and
• produce a report of the detected one or more KAFs on the web page.
