cy.session() for session caching in Cypress - Test Execution Trace

Test Overview

This test logs into a web application using cy.session() to cache the login session. It verifies that the user is successfully logged in by checking the presence of a logout button.

Test Code - Cypress

Cypress

describe('Login with session caching', () => {
  beforeEach(() => {
    cy.session('user-session', () => {
      cy.visit('/login')
      cy.get('#username').type('testuser')
      cy.get('#password').type('password123')
      cy.get('#login-button').click()
      cy.get('#logout-button').should('be.visible')
    })
  })

  it('should keep user logged in using cached session', () => {
    cy.visit('/dashboard')
    cy.get('#logout-button').should('be.visible')
  })
})

Execution Trace - 10 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test runner is ready to execute the test suite	-	PASS
2	cy.session() is called with key 'user-session' to cache login	No cached session exists yet	-	PASS
3	Browser opens and navigates to '/login'	Login page is displayed with username, password fields and login button	-	PASS
4	Finds username input field and types 'testuser'	Username field contains 'testuser'	-	PASS
5	Finds password input field and types 'password123'	Password field contains 'password123'	-	PASS
6	Finds and clicks the login button	Login form is submitted	-	PASS
7	Checks that logout button is visible to confirm login success	Dashboard page or logged-in state with logout button visible	Assert logout button is visible	PASS
8	Session 'user-session' is cached for reuse	Session data stored internally by Cypress	-	PASS
9	Test visits '/dashboard' page using cached session	Dashboard page loads without needing to login again	-	PASS
10	Checks that logout button is visible on dashboard	User is confirmed logged in on dashboard	Assert logout button is visible	PASS

Failure Scenario

Failing Condition: Login fails or logout button is not found after login attempt

Execution Trace Quiz - 3 Questions

What does cy.session() do in this test?

A Clears cookies before each test

B Reloads the page after login

C Caches the login session to reuse it in later tests

D Clicks the logout button automatically

Key Result

Using cy.session() improves test speed and reliability by caching login state, avoiding repeated login steps in each test.
