`Is there a way to maintain my AWS Amplify login credentials while executing Cypress tests?`

At the moment, I am using a beforeEach() function to log Cypress in before each test. However, this setup is causing some delays. Is there a way for me to keep the user logged in between tests?

My main objective is to navigate through all the pages as the logged-in user and identify any console warnings or errors.

Sample Code:

describe('Candidate Pages', () => {
  beforeEach(() => cy.loginByCognito(Cypress.env("candidate_username"), Cypress.env("candidate_password")));
  candidateRoutes.forEach((page) => {
    it(`No Console Errors for ${page}`, () => checkConsole(page, "error"));
    it(`No console.warn for ${page}`, () => checkConsole(page, "warn"));
  });
});

Answer №1

If you happen to come across the same page where you discovered cy.loginByCognito(), you will find an example of using sessions.

Additionally, we can optimize our login command by utilizing cy.session() to store the logged-in user so that reauthentication is not necessary for every test.

If you haven't reached that part yet, it's highly recommended to include it in your study.

// cypress/support/auth-provider-commands/cognito.ts
// Amazon Cognito
Cypress.Commands.add('loginByCognito', (username, password) => {
  cy.session(
    `cognito-${username}`,
    () => {
      return loginToCognito(username, password)
    },
    {
      validate() {
        cy.visit('/')
        // revalidate our session to ensure we are logged in
        cy.contains('Get Started').should('be.visible')
      },
    }
  )
})

Answer №2

When dealing with a login that sets a token, you can use cy.session()

After creating a session for a specific id, it will be stored in the cache throughout the spec file.

const login = (name) => {
  cy.session(name, () => {
    cy.visit('/login')
    cy.get('[data-test=name]').type(name)
    cy.get('[data-test=password]').type('s3cr3t')
    cy.get('#submit').click()
    cy.url().should('contain', '/home')
  })
  cy.visit('/home')
}

beforeEach(() => {
  login('user')
})

Additionally,

If you want to maintain a session across multiple specs, you can use the option cacheAcrossSpecs=true.

In such a scenario, remember to transfer the code to /support/e2e.js.
