Chai测试对象数组以“包含类似”的内容。对象子匹配 [英] Chai test array of objects to "contain something like" an object submatch

问题描述

好的。我在这里尝试阅读其他问题，但仍然找不到简单的答案。

Ok. I've tried to read other questions here but still didn't find a straightforward answer.

如何使用chai在数组中声明部分对象匹配？
类似以下内容：

How can I assert a partial object match in an array using chai? Something like the following:

var expect = require('chai').expect;
var data = [ { name: 'test', value: 'bananas' } ];
expect(data).to.be.an('array').that.contains.somethig.like({name: 'test'});

为了澄清，我的意图是尽可能地接近所提供的示例。

Just to clarify, my intention is to get as close to the example provided as possible.

• 链接到 .be.an（'array'）和


• 仅提供部分对象作为参数（与 chai-子集）。

• to chain after the .be.an('array') and
• to provide only the partial object as a parameter (unlike chai-subset).

我真的认为 expect（data）.to.be.an（'array'）。that .deep.contains（{name：'test'}）; 可以工作，但是由于不是部分匹配而失败，我有点儿被搞砸了。

I really thought that expect(data).to.be.an('array').that.deep.contains({name: 'test'}); would work, but it fails on not being a partial match and I'm kinda screwed there.

推荐答案

由于 chai-like@0.2.14 可以使用以下方法：

Since chai-like@0.2.14 the following approch will work:

var chai = require('chai'),
    expect = chai.expect;

chai.use(require('chai-like'));
chai.use(require('chai-things')); // Don't swap these two

expect(data).to.be.an('array').that.contains.something.like({name: 'test'});
