Postman : How to assert all array elements exist in other array?

rated 0 times [ 49] [ 7] / answers: 1 / hits: 7487 / 5 Years ago, fri, july 12, 2019, 12:00:00

I'm asserting for elements in array1 does exist in array2 or not, below are the array samples,

var array1 = [

        {

            name: appe,

            loc: war,

            order: 5,

            neck: NO,

            end: false

        },

        {

            name: con,

            loc: conve,

            order: 15,

            neck: NO,

            end: true

        }]



var array2 = [{neck:NO

end:true,

loc:conve,

name:con,

order:15

}]

code I tried -

const lodash = require(lodash);

    for(var i = 0; i < array2.length; i++ )

    {

            tests['response json contain Data'] = lodash._.has(points, array2[i]);

            //pm.expect(array2[i]).to.be.oneOf(array1);



    }

error I get -

response json contain Data | AssertionError: expected false to be truthy

EDIT
after trying another attempt2 -

pm.expect(array2[i]).to.be.oneOf(array1);

error -

AssertionError | expected { Object (name, loc, ...) } to be one of [ Array(20) ]

attempt3 -

pm.expect(array1).to.deep.equal(array2);

error -

AssertionError | expected [ Array(20) ] to deeply equal [ Array(18) ]

what I'm doing wrong?. what I want is if any one element in array2 is not in array1 it should fail.

Thanks

Chai assertion Library is included by Postman by default in its application. So you need to use the to.deep.equal. It will compare nested arrays as well as nested objects.

SOLUTION:

pm.test(verify two objects, function () {

  var array1 = [{

    name: appe,

    loc: war,

    order: 5,

    neck: NO,

    end: false

  },

  {

    name: con,

    loc: conve,

    order: 15,

    neck: NO,

    end: true

  }];



  var array2 = [{

    neck: NO,

    end: true,

    loc: conve,

    name: con,

    order: 15

  }, 

  {

    neck: NOo,

    end: true,

    loc: conve,

    name: con,

    order: 15

  }];



  pm.expect(array1).to.deep.equal(array2); // Failed

  pm.expect(array1).to.deep.equal(array1); // Passed



});
