Shift Left

    What is Shift Left Accessibility Testing?

    As modern software development practices continue to shift and change, one thing seems clear: the most cost-effective way to ensure the quality of your software is to catch defects as early as possible.

    When it comes to functional testing, the message has been heard loud and clear, but what about web and mobile accessibility testing?

    Traditional Accessibility

    Back in the day, accessibility testing had to happen at the end of the entire development cycle, if not after the delivery date.

    This was partly out of necessity: many accessibility initiatives are the result of end-users encountering live, inaccessible sites or applications and taking legal action to gain equal access to web-based content and services; and partly because the tools to embed accessibility throughout the development process didn’t exist.
