问我可以将我的测试分成不同的规范，然后从另一个规范中调用它们吗?还是使用helper函数更好？

EN

describe('tasty', function () {
    'use strict';
    var ptor;

    beforeEach(function () {
        ptor = protractor.getInstance();
        ptor.get('http://localhost:8000/');
    });

    it('Should sample three tasty fruits of every kind on my shopping list.', function () {
        ptor.findElement(protractor.By.className('fruitstore')).click();
        var fruitshelves = ptor.findElements(protractor.By.repeater('fruit in fruits').column('header'));

        fruitshelves.then(function(arr) {
            for (var i=0;i<arr.length; i++) { 
                // Pick up three fruits of this kind from the shelf and put in shopping cart
                // Should be listed on my shopping list 
                // Open the wallet
                // Should have money
                // Pay for the fruits and put it in your shopping bag
                // Should be able to complete the transaction

                // For each one of the fruits in your shopping bag
                // Take a bite
                // Should be tasty
            }
        });
    });
});
