What is the output of this Cypress test using cy.session()?

Consider the following Cypress test code that uses cy.session() to cache a login session. What will be the value of loginCount after running both tests?

Cypress

let loginCount = 0;

Cypress.Commands.add('login', () => {
  loginCount++;
  cy.visit('/login');
  cy.get('#username').type('user');
  cy.get('#password').type('pass');
  cy.get('button[type=submit]').click();
});

describe('Session caching test', () => {
  beforeEach(() => {
    cy.session('user-session', () => {
      cy.login();
    });
  });

  it('Test 1', () => {
    cy.visit('/dashboard');
  });

  it('Test 2', () => {
    cy.visit('/profile');
  });
});

AloginCount is 3 because cy.login() runs once per test plus once in beforeEach

BloginCount is 2 because cy.login() runs before each test

CloginCount is 0 because cy.login() is never called

DloginCount is 1 because cy.session caches the login for both tests

Which assertion correctly verifies that a session is cached with cy.session()?

You want to verify that the session caching works by checking that the login function is called only once. Which assertion below correctly tests this behavior?

Cypress

let loginCalls = 0;

Cypress.Commands.add('login', () => {
  loginCalls++;
  // login steps
});

describe('Session caching', () => {
  beforeEach(() => {
    cy.session('session-key', () => {
      cy.login();
    });
  });

  it('Test A', () => {
    cy.visit('/pageA');
  });

  it('Test B', () => {
    cy.visit('/pageB');
  });

  after(() => {
    // Assertion here
  });
});

Aexpect(loginCalls).to.equal(2);

Bexpect(loginCalls).to.equal(1);

Cexpect(loginCalls).to.be.lessThan(1);

Dexpect(loginCalls).to.be.greaterThan(1);

Why does this cy.session() test fail to cache the session?

Look at the code below. The session caching does not work as expected and the login function runs before every test. What is the most likely cause?

Cypress

let loginCount = 0;

Cypress.Commands.add('login', () => {
  loginCount++;
  cy.visit('/login');
  cy.get('#user').type('user');
  cy.get('#pass').type('pass');
  cy.get('button').click();
});

describe('Session caching failure', () => {
  beforeEach(() => {
    cy.session(() => {
      cy.login();
    });
  });

  it('Test 1', () => {
    cy.visit('/home');
  });

  it('Test 2', () => {
    cy.visit('/settings');
  });
});

Acy.session() must be called inside each test, not beforeEach

BThe login function has a syntax error causing it to rerun

CThe session key is missing in cy.session(), so it cannot cache sessions

Dcy.visit() inside login causes session caching to fail

How does cy.session() improve test performance in Cypress?

Which statement best explains how cy.session() improves test speed and reliability?

AIt caches browser cookies and local storage to avoid repeated login steps across tests

BIt runs all tests in parallel to reduce total execution time

CIt disables network requests during tests to speed up execution

DIt automatically retries failed tests to improve reliability

What happens if the session validation callback in cy.session() fails?

In cy.session(), you can provide a validation callback to check if the cached session is still valid. What is the behavior if this validation callback returns false or throws an error?

AThe cached session is discarded and the setup callback runs again to create a new session

BThe test fails immediately with a session validation error

CThe cached session is used anyway without re-running setup

DThe test retries the validation callback indefinitely until it passes
