James and attended a day-long workshop at React Finland on Design Systems with React presented by Andrey Okonetchnikov and Artem Sapegin (the creator of React Styleguidist). With that knowledge, today he will expand on his past talks by adding Cypress.io (a cool new e2e testing toolchain) to the mix. The goal is to advocate creating small behavior based tests at the component level (as opposed to or in addition to the application level) as a way to build developer confidence in a design system or component library built with React.
