Using fixtures in tests in Cypress - Test Execution Trace

Test Overview

This test loads user data from a fixture file and verifies the user's name appears on the page after login.

Test Code - Cypress

Cypress

describe('User Login with Fixture Data', () => {
  beforeEach(() => {
    cy.fixture('user').as('userData');
  });

  it('logs in and shows the user name', function() {
    cy.visit('/login');
    cy.get('#username').type(this.userData.username);
    cy.get('#password').type(this.userData.password);
    cy.get('#login-button').click();
    cy.get('#welcome-message').should('contain.text', `Welcome, ${this.userData.name}`);
  });
});

Step	Action	System State	Assertion	Result
1	Load fixture file 'user.json' and alias it as 'userData'	Fixture data is available for test use	-	PASS
2	Open the login page at '/login'	Login page is displayed in the browser	-	PASS
3	Find username input and type username from fixture	Username field contains the fixture username	-	PASS
4	Find password input and type password from fixture	Password field contains the fixture password	-	PASS
5	Click the login button	Login form submitted, page navigates or updates	-	PASS
6	Check that welcome message contains the user's name from fixture	Welcome message visible with correct user name	Verify welcome message text includes fixture user name	PASS

Failure Scenario

Failing Condition: Fixture file 'user.json' is missing or malformed, or selectors do not match page elements
