cy.mount() is the correct command to load Vue components for testing in Cypress.

What is the main reason to use simple selectors in mounted component tests?

A To make tests faster

B To hide elements from users

C To make tests easier to maintain

D To increase test complexity

Simple selectors help keep tests easy to read and maintain, reducing breakage when components change.

After mounting a Vue component, how do you simulate a button click in Cypress?
