How to write different tests to validate each iteration response on Single request-POST request-Postman

🙋 Help
1

Hi, I have a single POST request to which I pass 8 different sets of data while running collection using csv or json file.

ex:
{
“Id” : "{{ID}},
“name”: {{name}},
“email” : {{email}},
“phn” : {{phn}}
}
all fields are mandatory and i want to check mandatory error on leaving each field empty at each iteration.
I get Different response for each iteration and I want to validate my response message.
I need to validate a single line which looks like

var messageDetail = pm.response.json().MessageDetail
pm.test(“message”, function(){
pm.expect(messageDetail).to.equal.(“output which is different on each iteration”);
});

can anyone tell me how to do this, please??

Yes, you can use the CSV file to define a new column, say “expected_result” and there you can put what you have expected.

Next use use the pm.iterationData.get(“expected_result”) to fetch the value:

pm.expect(messageDetail).to.equal.(pm.iterationData.get("expected_result"));

Hi vdespa, thanks for your response,
But i am getting error on line
console.log(pm.iterationData.get(“expected_result”));
thier by i cannot add test like

pm.test(“MessageDetail”, function(){
pm.expect(messageDetail).to.equal(pm.iterationData.get(“expected_result”));
});
