Not able to remain signed in throughout a single test

[galiavasylieva]

I am using cypress-social-logins plugin to signin to the web application via Google.

I have:

1. custom command googlesignin in support/commands.js that has following:

Cypress.Commands.add('googlesignin', (usrn, pwd, verifSelector) => {
  const username = usrn;
  const password = pwd;
  const loginUrl = 'url_to_the_page_that_has_signup_with_google_button';
  const cookieName = 'cookie_name';
  const postLoginSelector = verifSelector;
  const socialLoginOptions = {
    username: username,
    password: password,
    loginUrl: loginUrl,
    headless: true,
    logs: true,
    loginSelector: 'a[href="/api/auth/google"]',
    postLoginSelector: postLoginSelector,
  };

  return cy
    .task('GoogleSocialLogin', socialLoginOptions)
    .then(({ cookies}) => {
      cy.clearCookies();
      const cookie = cookies
        .filter((cookie) => cookie.name === cookieName)
        .pop();
      if (cookie) {
        cy.setCookie(cookie.name, cookie.value, {
          domain: cookie.domain,
          expiry: cookie.expires,
          httpOnly: cookie.httpOnly,
          path: cookie.path,
          secure: cookie.secure,
          session: cookie.session,
          sameSite: cookie.sameSite,
          size: cookie.size,
        });
        Cypress.Cookies.defaults({
          preserve: cookieName,
        });
      }
    });
});

2. plugins/index.js file with:

const { GoogleSocialLogin } = require('cypress-social-logins').plugins;
module.exports = async (on, config) => {
  on('task', {
    GoogleSocialLogin: GoogleSocialLogin
  });
  return config;
};

3. My test:

  describe('SocialSignin', () => {
  beforeEach(() => {
    cy.visit('/signin');
  });
    it('user expects to be able to signin with the Gmail account', () => {
      cy.googlesignin(
        Cypress.env('registeredGoogleUsername'),
        Cypress.env('registeredGooglePassword'),
        'a',
      );
      cy.visit("/signup")
      cy.url().should('contain', '/home');
    });

ACTUAL BEHAVIOUR:

The test is passing.
When I set headless: false in socialLoginOptions - I can see puppeteer going through all the process, logging in with google.
Cookies are being set as well.

BUT When it gets to the cy.visit("/signup") step <---- I expect to be redirected to /home (that is by our app design and working as expected manually), but instead I end up on /signup page UNAUTHENTICATED.
