The response body looks like this.

        "id": 1,
        "wardName": "Unit1"
        "id": 2,
        "wardName": "Unit2"
        "id": 3,
        "wardName": "Unit3"
        "id": 4,
        "wardName": "Unit4"

Here, I need to verify whether the ward names (Unit1, Unit2, Unit3, and Unit4) have correct values.


You can create a Postman test:

pm.test("Checking wardNames", () => {
  const responseJson = pm.response.json();

Of course, you can code these assertions differently as you want.

  • Hi Joāo, Thank you for the answer. I have tried with that but gives the following error. "Checking wardNames | TypeError: Cannot read property '0' of undefined" Oct 25 '21 at 7:29

    @kasunigunasekera: there should be no list, the array from the response is already accessible through responseBody, so pm.expect(responseJson[0].wardName).to.eql('Unit1'); is how to write these checks. Also eql() has to take a string, Unit1 without quotes will try to find a variable with such a name. More on that in Postman docs learning.postman.com/docs/writing-scripts/script-references/…

  • @pavelsaman That worked! Thanks a lot, both. Oct 25 '21 at 8:31

    Yeah, I assumed there would be some object of type list, not a list on the root of a JSON object - this design is odd. Oct 25 '21 at 13:59
