Preserve cookies / localStorage session across tests in Cypress

Question

I want to save/persist/preserve a cookie or localStorage token that is set by a cy.request(), so that I don\'t have to use a custom command to login on ever

Answer 1

I can see suggestions to use whitelist. But it does not seem to work during cypress run. Tried below methods in before() and beforeEach() respectively:

Cypress.Cookies.defaults({
  whitelist: "token"
})

and

Cypress.Cookies.preserveOnce('token');

But none seemed to work. But either method working fine while cypress open i.e. GUI mode. Any ideas where I am coming short?
