Chai - Testing for values in array of objects

Question

I am setting up my tests for the results to a REST endpoint that returns me an array of Mongo database objects.

[{_id: 5, title: \'Blah\', owner: \'Ted\', de         


        

Answer 1

ES6+

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

something like:

const data = [{_id: 5, title: 'Blah', owner: 'Ted', description: 'something'},{_id: 70, title: 'GGG', owner: 'Ted', description: 'something'}];


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

or even shorter if you only check one key:

expect(data.map(e=>(e.title))).to.include("Blah");
