Functional tests

Tests are in the folder cypress/integration

• login-spec.js shows successful and unsuccessful login via user interface
• feeds-spec.js shows how to login using XHR request bypassing the login form UI
• new-post-spec.js adds a new post
  • before each test, all existing posts are deleted using cy.task('deleteAllArticles') command. This task is defined in cypress/plugins/index.js file.
  • before each test, we log the user in via custom command cy.login() defined in cypress/support/index.js file
  • we also import the post content using import directives, the post itself is in file cypress/fixtures/post.js

The test writing and organization are covered in slides at https://slides.com/bahmutov/flawless-tests

Test setup

• installed Cypress with npm i -D cypress
• scaffolded Cypress folder with npx @bahmutov/cly init
• set the base url in cypress.json file

{
  "baseUrl": "http://localhost:4100"
}

• manually made a test user account: [e-mail] password1234 and set the user profile picture to https://robohash.org/6FJ.png?set=set3&size=150x150

• looked at the login action. The user logs in via XHR call to POST http://localhost:3000/api/users/login which returns JWT and sets it in local storage under jwt key. The payload to login is {user: {email: "[e-mail]", password: "password1234"}}. Implemented the same functionality using cy.request by grabbing the user account object from cypress.json environment object

describe('Conduit', () => {
  beforeEach(() => {
    cy.request('POST', 'http://localhost:3000/api/users/login', {
      user: Cypress.env('user'),
    })
      .its('body.user.token')
      .should('exist')
      .then((token) => {
        localStorage.setItem('jwt', token)
      })

    cy.visit('/')
  })

  it('shows feeds', () => {
    cy.contains('a.nav-link', 'Your Feed').should('have.class', 'active')
    cy.contains('a.nav-link', 'Global Feed').should('not.have.class', 'active')
  })
})

And we are in business!

Tip: find different ways to quickly login in Logging in recipes.
