// MISSION BRIEF
Your Mission
Cypress runs two kinds of war: component testing (mount one component, iterate fast) and e2e (drive the deployed app like a user). Teams that blur the line get slow component tests and shallow e2e suites.
Six questions on what each mode is for. Speed bonus active.
// FIRST CONTACT
Battle teaser
What does cy.mount actually do in a component test?
- ADeploys the app to a temporary server first
- BRenders the component to an HTML string and diffs it
- CVisits the production URL and scrolls to the component
- DRenders a single component in the browser via your project's dev server (Vite/webpack), no running application or backend required
Answers, scoring, hints, and the full battle stay sealed.
