Frontend Testing with Cypress: Ensuring a Flawless User Experience

Our secret to delivering top-notch user experiences lies in thorough frontend testing. We rely on Cypress, a powerful JavaScript testing tool, to take our frontend projects to the next level.

Importance of Frontend Testing using Cypress

In an ever-evolving digital world, flawless user interfaces are key to keeping users engaged. We use Cypress for its straightforward setup, real-time feedback, focus on usability, and consistent results. It also supports popular frameworks like React, Angular, and Vue, making it our go-to testing tool.

Setting Up Cypress Tests

Install Cypress as a dependency:

npm install cypress --save-dev

Add Cypress commands to your package.json file:

{
  "scripts": {
    "test": "npx cypress open",
  }
}

Run Cypress for the first time:

npm run test

A Simple Cypress Test Example

Create a new file within the cypress/e2e directory and name it my_first_test.cy.js.
Add the following code to the file:

/// <reference types="cypress" />
 
describe('example to-do app', () => {
  beforeEach(() => {
    cy.visit('https://example.cypress.io/todo')
  })
 
  it('displays two todo items by default', () => {
    cy.get('.todo-list li').should('have.length', 2)
 
    cy.get('.todo-list li').first().should('have.text', 'Pay electric bill')
    cy.get('.todo-list li').last().should('have.text', 'Walk the dog')
  })
})

Start your development server, then run Cypress:

npm run test

Select the new test file from the Cypress Test Runner, and watch the magic happen.
