Using unquoted property names causing syntax errors.

The property name must be a string, so it needs quotes around 'userId'.

Fill both blanks to extract the 'name' from the JSON response and check if it equals 'John'.

Postman

const name = pm.response.json().[1];
pm.test('Name is John', function () { pm.expect(name).[2]('John'); });

Drag options to blanks, or click blank then click option'

Common Mistakes

Using wrong property names or incorrect assertion methods.

Access the 'name' property and use 'to.equal' to check exact equality.

5fill in blank

hard

Fill all three blanks to create a test that checks if the response time is less than 500ms and the response has a header 'Content-Type' with value 'application/json'.

Postman

pm.test('Response time and header check', function () {
  pm.expect(pm.response.responseTime).[1](500);
  pm.expect(pm.response.headers.get([2])).[3]('application/json');
});

Drag options to blanks, or click blank then click option'

Ato.be.below

B'Content-Type'

Cto.equal

Dto.be.above

💡 Hint

Common Mistakes

Using wrong assertion methods or header names without quotes.

Use 'to.be.below' to check response time less than 500ms, get the 'Content-Type' header as a string, and check it equals 'application/json'.
