Code coverage plugin in Cypress - Test Execution Trace

Test Overview

This test uses Cypress with a code coverage plugin to check if the homepage loads and the main heading is visible. It verifies that the heading text matches the expected value and that code coverage data is collected during the test.

Test Code - Cypress

Cypress

/// <reference types="cypress" />

describe('Homepage Code Coverage Test', () => {
  beforeEach(() => {
    cy.visit('https://example.cypress.io')
  })

  it('checks main heading and collects coverage', () => {
    cy.get('h1').should('be.visible').and('contain', 'Kitchen Sink')
  })
})
