Hi All,

Quick question on while loops. I am trying to do it on an include, but JS keeps complaining. Can someone point out the obvious please?

```
var i = 1;

while (i <=10)

{

    if ((pm.response.json()[i].to.include("Howdy"))

    {

        pm.test("Howdy was found in Page");

    }

i++;

}

```

When i try to run as a test i am told:

There was an error in evaluating the test script: TypeError: pm.response.text(…)[attemptCount].to.include is not a function

Any help is appreciated.

Hi @JBird20 👋

Not entirely sure, but from what I see: the if commands have an extra `(` preventing this from compiling. Could you remove the same and see if that helps?

> if (pm.response.json()[i].to.include(“Howdy”))

If the issue persists, could you provide us some screenshots or further details on your workflow which would help us identify this better?

Hey,

sorry for the late response.

I have update the loop as you have advised. However, i think the issue i am now having is more to do with the body response type.

In the code i am doing

```
if (pm.response.json()[i].to.include(“Howdy”))

```

However, the response body comes back as HTML. Is there a way to do

```
if (pm.response.html()[i].to.include(“Howdy”))

```

as when i try i get the following:

JSON:

> There was an error in evaluating the test script: JSONError: Unexpected token ‘\<’ at 6:1 ^

HTML

> There was an error in evaluating the test script: TypeError: pm.response.html is not a function

And this just Locks up Postman

```
var i = 1;

while (i <=10);

const $ = cheerio.load(pm.response.text());

//output the html for testing

data = $.html();

{

    if (data()[i].to.include("Howdy"))

    {

        pm.test("Howdy was found in Page");

    }

i++;

}

```

@JBird20, would it be possible for you to share the response the API is returning? Or better yet, is this a public endpoint? It will be easier to assist if we can see the response being returned. I’d also recommend seeing if this particular endpoint can return JSON ( may be documented in the API ).  
Regarding the error `There was an error in evaluating the test script: JSONError: Unexpected token ‘<’ at 6:1 ^`

That’s normal as you’re trying to parse a JSON object, but on a response that isn’t JSON, so it throws an error.

The second error is straightforward; you’re attempting to call the HTML() method on pm.response but that’s not a function. You can take a look at the sandbox here: [https://www.postmanlabs.com/postman-collection/Response.html](https://www.postmanlabs.com/postman-collection/Response.html) for some of the available methods on the Response. You could try using [pm.response.toJSON()](https://www.postmanlabs.com/postman-collection/Response.html#toJSON) and work from there if that helps.

Regarding your loop. It locks up because looking at the code it looks like your loop is the following:  
`while (i <=10);` This condition will always be true, so it’s an infinite loop. It should be:

```auto
while(i <=10 ){
// do something
i++;

}

```

I hope this helps!
