Integration Testing
Most UI tests should center around integration testing. Cypress is really good at end to end and integration testing so it makes a great tool for this.
Here's the canonical tweet:
Integration testing largely tests at the HTTP level. So you would test GET /
instead of a component like import Index from '.'
Testing in the browser also allows you to avoid mocking out unsupported browser features in a node environment. I have often found this to be the most annoying part of jest tests
Integration tests with Cypress allow me to test workflows in UI's without messing around with low level details.
Often I really just want to mock data from HTTP requests and see how the interface responds to those cases.
