Cypress - Authentication and Sessions

You wrote this code to preserve cookies but the second test fails because the cookie is missing:

beforeEach(() => {
  Cypress.Cookies.preserveOnce('auth_token')
})

it('Login test', () => {
  cy.setCookie('auth_token', 'xyz789')
})

it('Dashboard test', () => {
  cy.getCookie('auth_token').should('exist')
})

What is the likely cause of the failure?

AThe cookie is set after the beforeEach hook runs, so it is not preserved

BThe cookie name is misspelled in preserveOnce

CCypress cannot preserve cookies between tests

DThe assertion syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Understand when preserveOnce runs
The beforeEach hook runs before each test, so it preserves cookies existing before the test starts.
Step 2: Analyze cookie setting timing
The cookie is set inside the first test, after beforeEach runs, so it is not preserved for the next test.
Final Answer:
The cookie is set after the beforeEach hook runs, so it is not preserved -> Option A
Quick Check:
PreserveOnce must run after cookie set [OK]

Quick Trick: Set cookies before preserveOnce runs to keep them [OK]

Common Mistakes:

Thinking preserveOnce preserves cookies set during the test
Assuming Cypress can't preserve cookies
Blaming assertion syntax instead of timing
