How do I check that there is no specific data in postman response?

Question

I am sending a request that creates an issue in postman. I get a json data in response and I need to check that this data does not contain specified element. How do I do it in tests?

Answer 1

To confirm that a value is missing from the json response, you can use pm.expect(jsonResponse.value).to.be.undefined .

Here is the full example:

pm.test("valueThatShouldNotBePresent is missing from the json response", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.valueThatShouldNotBePresent).to.be.undefined;
});

Also we can do the following:

  const jsonData = pm.response.json()
    pm.test('Key abc is absent', () => {
        pm.expect(jsonData).to.not.have.any.keys('abc')
    })
