Checking that an ID is appearing or not in my Response Body


I am using an API to add and delete movies from a list, I’m using postman collection variables to take the id of the new movie I added so that I can use it in some tests. Here is an example of what the list of movies looks like:


    "actors": "Kevin Zegers, Rip Torn",

    "category": "Popular",

    "director": "Peter Hewitt",

    "genres": "Action, Adventure, Family, Sci-Fi",

    "id": 1457,

    "imdb": "",

    "language": "English",

    "minutes": 83,

    "rating": 4,

    "stock": 3,

    "title": "Zoom",

    "year": 2006



    "actors": "Orlando Bloom, Tanya van Graan",

    "category": "Regular",

    "director": "Jérôme Salle",

    "genres": "Crime, Drama, Thriller",

    "id": 2516,

    "imdb": "",

    "language": "English",

    "minutes": 110,

    "rating": 3,

    "stock": 2,

    "title": "Zulu",

    "year": 2013



Using the last entry with an id of 2516 as an example, I want the test to either log that the movie exists in the list based on its id or if it doesn’t exist. So far I have tried this but it doesn’t quite work:

if(pm.response.text().includes(pm.collectionVariables.get(“idData”)) === true) {

console.log("Movie exists within the list");


else {

console.log("Movie no longer exists in the list")


I’m sure I’m doing something wrong or missing something. There’s probably a better way of doing it. I appreciate any help.
