Yet, acknowledging accessibility as both a social responsibility and a driver for product quality and innovation, resulting in business value, seems to be no priority for most organizations. The reason for this is simple: a lack of awareness and practice. 

We have integrated automated tests as a crucial part in our development flow, profiting from faster feedback cycles and enabling continuous integration. Nevertheless accessibility is often tested - if at all - on a manual or end-to-end test level, leading to longer feedback times, higher test fragility and increased implementation costs. 

In this talk we are going to explore how established testing patterns, such as the testing pyramid, can be applied in the context of accessibility and can help us to overcome these challenges, as well as improve the product quality.
