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 itmy_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.
