When submitting an order to an API we get a Json response containing:

"AMLResults": [
        "amlResult": [
                "addresses": [
                        "flatNo": "Flat 1",
                        "houseNumber": "32",
                        "line1": "Ayr Street",
                        "line2": "",
                        "town": "GLASGOW",
                        "postcode": "G21 4DG"

And then I'm trying to test that the address is returned and formatted correctly

let amlResult = {};
pm.test("response should contain a formated client address",function(){
jsonData = pm.response.json();
addresses = amlResult.addresses;
    pm.expect(addresses).to.have.property('flatNo', 'Flat 1');
    pm.expect(addresses).to.have.property('houseNumber', '32');
    pm.expect(addresses).to.have.property('line1', 'Ayr Street');
    pm.expect(addresses).to.have.property('line2', '');
    pm.expect(addresses).to.have.property('town', 'GLASGOW');
    pm.expect(addresses).to.have.property('postcode', 'G21 4DG');

However I keep getting the following failure response:

response should contain a formated client address | AssertionError: expected {} to have property 'addresses'

Any help would be appreciated.


Firstly, at


amlResult is an empty object, defined outside the test.

You may want something like this:

const firstAmlResult = jsonData.AMLResults[0];

Now you can inspect this AML Result object:

const result = firstAmlResult.amlResult[0]

const address = result.addresses[0]
pm.expect(address ).to.have.property('flatNo')
pm.expect(result.flatNo).to.eql('Flat 1')

However, for all to.have.property checks, a better approach would be a Schema Validation. Tip #4 of this blog post explains it.

Validating by JSON Path Match:

var jsonData = pm.response.json();
pm.test("Check for house number", function () {

You can also use an array find function.

var jsonData = pm.response.json();
var result = jsonData.find(x =>x.AMLResults.amlResult.addresses.flatNo ==="Flat 1");
pm.environment.set("houseNumber", result.houseNumber);

You'll look for the object where flatNo is "Flat 1"
Store the other values like houseNumber in a variable of set it as an environment variable.

So you can validate their value:

var jsonData = pm.response.json();
pm.test("Check if houseNumber is correct", function () {
    var houseNumber = pm.environment.get("houseNumber "); 
    pm.expect(houseNumber ).to.eql(32);
