Cypress E2E Testing Patterns

Quick Guide: Cypress runs inside the browser alongside the application. Commands are enqueued rather than executed, so nothing they produce can be read out of a const — use .then() or an alias. Select with data-cy attributes, wait on cy.intercept() aliases rather than on milliseconds, and cache authentication with cy.session(). Cypress 15 is current stable; cy.origin() has been required for any cross-origin navigation since 14, and Cypress.env() is deprecated in favour of cy.env() and Cypress.expose().
