Braydon Coyer Yes! Specifically, Next.JS with Jest/React Testing Library. I've set up all our Webpack configurations and the couple of unit tests I've fired off have been successful. (Your article will be helpful moving forward with more of those!)
However, as a small team, we want to largely focus on Integration testing for best bang for buck. I'm wondering about things like folder methodology and approaches similar to what you've described here to break things down.
There's a lot of content on unit testing but less so on Integration and E2E.
In the future, if we do E2E, I'll integrate Cypress.
