Hi guys.

Can anyone tell me how to write a test that will count how many objects I have nested in JSON in the response.  
I don’t know the number, so “to.equal” is out of the question.  
I would like Postman to return a number in the console.  
PS.  
I searched the forum, none of the answers worked.  
Thanks!!!

Postman uses JavaScript, so I would recommend searching the web with JavaScript in the title.

You have an object called data, with an array of objects called ib\_clients.

I assume you mean the number of objects in that array which you can use the array.length() method.

[JavaScript Array length Property (w3schools.com)](https://www.w3schools.com/jsref/jsref_length_array.asp)

```auto
const response = pm.response.json();
console.log((data.ib_clients).length);

```

This will return the number in the console logs, but I can’t see how you can craft an appropriate test for this unless you know what the expected number will be.

This works perfect 🙂

var body = JSON.parse(responseBody);

tests["Array length is " + body.data.ib\_clients.length] = true;
