【问题描述】:
我正在尝试使用 Mocha 和 Chai 在 JavaScript 中编写测试。在测试结束时,我想比较 2 个 JavaScript 对象,它们应该相等。
我从测试中得到的输出如下:
{ publication:
{ publication_id: 'pubFetch1',
title: 'Publication Fetcher',
person_id: 'uploader',
URL: 'http://www.pubfetchertest.com',
publication_year: '2015',
upload_date: '2015-05-05 00:00:00',
page_count: '5',
type: 'paper',
rating: '0',
votes: '0',
abstract: 'Testing the Publication Fetcher',
location: 'location' },
comments:
[ { commentID: 'comment1',
personID: 'uploader',
firstName: 'First',
lastName: 'Last',
text: 'Comment Content',
time: '2015-05-05 10:24:36',
reactions: [],
myComment: true },
{ commentID: 'comment2',
personID: 'author1',
firstName: 'First',
lastName: 'Last',
text: 'Comment Content',
time: '2015-05-05 11:01:45',
reactions: [Object],
myComment: false } ],
keywords: [ 'keyword1', 'keyword2', 'keyword3' ],
uploader: { person_id: 'uploader', first_name: 'First', last_name: 'Last' },
score: 5,
authors:
[ { person_id: 'author1', first_name: 'First', last_name: 'Last' },
{ person_id: 'author2', first_name: 'First', last_name: 'Last' },
{ person_id: 'author3', first_name: 'First', last_name: 'Last' } ],
editors: [],
publishers: [] }
虽然我想与之比较的对象如下:
{ publication:
{ publication_id: 'pubFetch1',
title: 'Publication Fetcher',
person_id: 'uploader',
url: 'http://www.pubfetchertest.com',
publication_year: '2015',
upload_date: '2015-05-05 00:00:00',
page_count: '5',
type: 'paper',
rating: '0',
votes: '0',
abstract: 'Testing the Publication Fetcher',
location: 'location'},
comments:
[{ commentID: 'comment1',
personID: 'uploader',
firstName: 'First',
lastName: 'Last',
text: 'Comment Content',
time: '2015-05-05 10:24:36',
reactions: [],
myComment: true},
{ commentID: 'comment2',
personID: 'author1',
firstName: 'First',
lastName: 'Last',
text: 'Comment Content',
time: '2015-05-05 11:01:45',
reactions: [{ commentID: 'comment3',
personID: 'author2',
firstName: 'First',
lastName: 'Last',
text: 'Comment Content',
time: '2015-05-05 11:02:10',
reactions: [],
replyID: 'comment2',
myComment: false}],
myComment: false}],
keywords: ['keyword1', 'keyword2', 'keyword3'],
uploader: {person_id: 'uploader',
first_name: 'First',
last_name: 'Last'},
score: 5,
authors: [{person_id: 'author1',
first_name: 'First',
last_name: 'Last'},
{person_id: 'author2',
first_name: 'First',
last_name: 'Last'},
{person_id: 'author3',
first_name: 'First',
last_name: 'Last'}],
editors: [],
publishers: []
};
我看不出这两个对象有什么不同,那么为什么 JavaScript 会说它们不同呢?我正在使用JSON.stringify(obj1) === JSON.stringify(obj2) 来比较这两个对象。

【问题讨论】:
-
能否提供jsfiddle/plunker?
-
不看对象:在 JavaScript 中,对象属性没有任何特定的顺序。因此,一个对象的 JSON 表示可能看起来与另一个具有相同内容的对象的 JSON 表示不同。
-
如果您使用该工具来帮助您,您可以真正找出差异。有些键不一样。
