'how to exclude few files/folder from using preserved cypress cookies

I am trying to preserve cookies in index.js file :

Cypress.Cookies.defaults({
  preserve: ['session_id', 'remember_token'],
})

But I want to exclude few files such as login/authentication files from using the preserved cookies because I want to test real login here.

I see that cypress provides something like:

Cypress.Cookies.defaults({
  preserve: (cookie) => {
    // implement your own logic here
    // if the function returns truthy
    // then the cookie will not be cleared
    // before each test runs
  },
})

But I am not sure how to exclude a folder/files inside this. If someone has an idea kindly help. Or if there is any other better option to exclude files from using preserved cookies do let me know

I don't believe there is a way to exclude Cookies based on what spec file is running. Instead, you could clear them in the specs that you do not want values, and create a helper to check they are set in the specs.

// support/index.js
...
Cypress.Cookies.defaults({
  preserve: ['session_id', 'remember_token'],
})
Cypress.Commands.add('setDefaultCookies', () => {
  const defaults = { 'session_id': 'foo', 'rememberToken': 'bar' }
  cy.getCookies().then((cookies) => {
    for (const [key, value] of Object.entries(defaults) {
      // use `find` to check if we have the specified cookie
      const found = cookies.find(x => x.name === key);
      if (!found) {
        cy.setCookie(key, value);
      }
    };
  });  
});
...

// auth.spec.js (doesn't want cookies)
...
before(() => {
  cy.clearCookies();
});
...

// foo.spec.js (wants cookies)
...
before(() => {
  cy.setDefaultCookies();
});
...

In the Cypress.Cookies.defaults preserve function you can return true or false depending on the cookie properties and the current spec properties.

Cypress.Cookies.defaults({
  preserve: (cookie) => {

    const isLogin  = Cypress.spec.name.contains('login') ||  // e.g login.spec.js
      Cypress.spec.relative.contains('login');               // e.g /login-tests/...

    if (cookie.name === 'token' && isLogin {
      return false
    } else {
      return true
    }
  },
})
