Working in the Shadow (DOM) - How to test Web Components by David Burns #SeConf 2022

As Web Components gain more traction in the web to help websites become more performant it has created a bit of a blind spot on how to test these new features.

In this talk, David will walk you through what Web Components are and how they are benefiting the web as we move forward. He will then walk you through how we can go about testing these and how, while well-meaning, other frameworks are making things a little harder to test. He will also go through some of the performance aspects of the Web Components and how this translates to your tests.
