medium📝 Predict Output Q4 of 15
Cypress - Authentication and Sessions
Analyze this Cypress code:
beforeEach(() => {
  cy.session('userSession', () => {
    cy.visit('/login')
    cy.get('#username').type('user')
    cy.get('#password').type('pass')
    cy.get('button[type=submit]').click()
  })
})

What impact does this have on the test suite's execution speed?
AIt causes tests to fail due to missing session id parameter.
BIt slows down tests because login runs before every test without caching.
CIt speeds up tests by caching the login session, avoiding repeated logins.
DIt has no effect since <code>cy.session()</code> is deprecated.
Step-by-Step Solution
Solution:
  1. Step 1: Understand cy.session() behavior

    This command caches the session identified by 'userSession'.
  2. Step 2: Effect on test speed

    Login steps run once per session, then reused, reducing redundant login time.
  3. Final Answer:

    It speeds up tests by caching the login session, avoiding repeated logins. -> Option C
  4. Quick Check:

    Session caching reduces login overhead [OK]
Quick Trick: Session caching runs login once, speeds tests [OK]
Common Mistakes:
  • Assuming login runs before every test despite caching
  • Confusing session id usage
  • Believing cy.session() is deprecated
