JSON fixture files in Cypress - Test Execution Trace

Test Overview

This test uses a JSON fixture file to load user data and verifies that the user name is displayed correctly on the page.

Test Code - Cypress

Cypress

describe('User Profile Test with JSON Fixture', () => {
  beforeEach(() => {
    cy.visit('/user-profile')
  })

  it('displays user name from fixture', () => {
    cy.fixture('user').then((user) => {
      cy.get('#user-name').should('contain.text', user.name)
    })
  })
})

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test runner initialized, no browser opened yet	-	PASS
2	Browser opens and navigates to '/user-profile'	User profile page is loaded in the browser	-	PASS
3	Loads JSON fixture file 'user.json'	Fixture data with user details is available	-	PASS
4	Finds element with id 'user-name'	User name element is present on the page	-	PASS
5	Checks that element '#user-name' contains text from fixture user.name	User name text is visible on the page	Assert element text equals fixture user.name	PASS

Failure Scenario

Failing Condition: The element with id 'user-name' is missing or the fixture file 'user.json' is not found or malformed

Using JSON fixture files in Cypress helps separate test data from test code, making tests cleaner and easier to maintain.
