Chai test array of objects to “contain something like” an object submatch

Question

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

How can I assert a partial object match in an array using chai? Something

ES6+

Clean, functional and without dependencies, simply use a map to filter the key you want to check

something like:

const data = [ { name: 'test', value: 'bananas' } ];
expect(data.map(e=>e.name)).to.include("test");

and if you want to test multiple keys:

expect(data.map(e=>({name:e.name}))).to.include({name:"test"});
