Question

似乎我做了

describe( 'Add Youtube', function () {

    it( 'should return the video data, including user, title and content fields', function ( done ) {

        this.timeout( 5000 )

        request({
            method: 'POST',
            url: 'https://localhost:8443/api/add',
            json: true,
            strictSSL: false,
            body: {
                "type": "youtube",
                "url": "https://www.youtube.com/watch?v=uxfRLNiSikM"
            },
            headers: {
                "Authorization": "Bearer " + newTestUser.token
            } }, function ( err, response, body ) {

                body.should.include.keys( [ "user", "title", "content" ] )

                done()
        })
    })
})

这会返回错误，因为回来的对象也有密钥message。只要数组中的3个键存在，我怎么能让它返回传递，尽管还有更多。我无法预测每种情况下的情况。

更新：以下是我要求Chai和should的方式。

var chai = require( 'chai' ),
    chaiAsPromised = require( 'chai-as-promised' ),
    should = require( 'chai' ).should(),
    path = require( 'path' ),
    getUser = require( '../helpers/get-user' ),
    userController = require( '../controllers/userController' ),
    blogController = require( '../controllers/blogController' ),
    request = require( 'request' ),
    User = require( '../models/userModel' ),
    Content = require( '../models/contentModel' ),
    shortid = require( 'shortid' )

chai.use( chaiAsPromised )

Answer 1

如果您有像这样的对象（类似于您所描述的）：

var obj= {
  user: "user",
  title: "title",
  content: "content",
  message: "message"
};

以下所有断言都应该通过：

obj.should.include.keys(["user", "title", "content"]);
obj.should.includes.keys(["user", "title", "content"]);
obj.should.contain.keys(["user", "title", "content"]);
obj.should.includes.keys(["user", "title", "content"]);

即使您将值作为单独的参数传递：

obj.should.include.keys("user", "title", "content");
obj.should.includes.keys("user", "title", "content");
obj.should.contain.keys("user", "title", "content");
obj.should.includes.keys("user", "title", "content");

因此，假设您正确地需要chai＆＃39; should样式：

var should = require('chai').should();

，您的问题可能只是body对象或测试套件中的错字。

更新：在您添加了有关所有测试模块所需方式的更多信息后，应指出以下几点：

首先，您需要chai两次，第二次需要设置should。你做了：

var chai = require( 'chai' ),
    should = require( 'chai' ).should(),
    ...

你应该完成的时间：

var chai = require( 'chai' ),
    should = chai.should(),
    ...

其次，如果您正在使用chai-as-promised，则应该设置body个密钥the way this module requires，例如：
```
Promise.resolve(body).should.eventually.include.keys([ "user", "title", "content" ]);
```

Answer 2

在您的请求处理程序中，最简单的解决方案是：

function ( err, response, body ) {
  var expected={},
      expected_keys=['user','title','content'];

  expected_keys.forEach(function(key){
    expected[key]=body[key];
  });

  expected.should.include.keys(expected_keys);

  done();
}

或者使用我最喜欢的工具lodash：

var _=require('lodash');

function ( err, response, body ) {
  var expected_keys=['user','title','content'];

  _.pick(body,expected_keys).should.include.keys(expected_keys);

  done();
}

给Chai / Mocha一个应该包含的部分密钥列表
