Mocha, Chai: Assert that Object is included in an Array of Objects
提问by mck
Chai has a nice way to assert if an Array includes a certain element
Chai 有一个很好的方法来断言数组是否包含某个元素
expect([1,2,3]).to.include(2);
What I would like is something similar, given an Array of Objects:
给定一个对象数组，我想要的是类似的东西：
expect([{a:1},{b:2}]).to.include({b:2});
Is this possible?
这可能吗？

Take a look at the Chai Things plugin, that does what you want:
看看Chai Things 插件，它可以满足您的需求：
[{a:1},{b:2}].should.include.something.that.deep.equals({b:2})

Here is an alternative and non order dependent approach for collections:
这是集合的另一种非顺序依赖方法：
array
大批
expect([1, 2, 3]).to.include.members([3, 2, 1])
You can also use this with a deepflag for comparison of objects:
您还可以将其与deep标志一起使用以比较对象：
array of objects
对象数组
expect([{ id: 1 }]).to.deep.include.members([{ id: 1 }]);
object
目的
expect({foo: 'bar', width: 190, height: 90}).to.include({ height: 90, width: 190 })

You can use deep method for the array of objects.
您可以对对象数组使用 deep 方法。
expect([{a:1},{b:2}]).to.deep.include({b:2}); //It will pass
You can find more examples using deep method here: http://chaijs.com/api/bdd/#method_deep
你可以在这里找到更多使用深度方法的例子：http: //chaijs.com/api/bdd/#method_deep
The main point to remember here is about reference types.
这里要记住的要点是关于引用类型。
