JEST why I cant console.log all testids?

Question

Why I can not see all my testIDs ?

if I console.log this: page.getAllByTestId then I get this:

 page: function getAllFn(args, queryOptions) {
          const results = queryAllByQuery(instance)(args, queryOptions);

          if (results.length === 0) {
            throw new _errors.ErrorWithStack(getMissingError(args), getAllFn);
          }

          return results;
        }

      at Object.<anonymous> (__tests__/App-Input-test.js:10:13)

code:

import React from 'react';
import Login from '../components/Login';
import { render } from '@testing-library/react-native';

describe('Login Screen', () => {

  it('should go to home page on login', () => {
    const page = render(<Login />)

    console.log('page: ' + page.getAllByTestId);

  });

});
