Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if the response status is 200.

Postman

pm.test('Status code is 200', function () { pm.response.to.have.status([1]); });

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

💡 Hint

Common Mistakes

Using wrong status codes like 404 or 500.

The status code 200 means the request was successful. Checking this confirms the response is correct.

2fill in blank

medium

Complete the code to check if the response body contains the key 'success'.

Postman

pm.test('Response has success key', function () { pm.expect(pm.response.json()).to.have.property([1]); });

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

A'status'

B'error'

C'success'

D'message'

💡 Hint

Common Mistakes

Using wrong key names like 'error' or 'message'.

Checking for the 'success' key confirms the response includes expected data.

3fill in blank

hard

Fix the error in the assertion to check if the response time is less than 200ms.

Postman

pm.test('Response time is fast', function () { pm.expect(pm.response.responseTime).to.be.[1](200); });

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

💡 Hint

Common Mistakes

Using 'lessThan' which is not a valid Chai method.

The correct assertion method is 'below' to check response time is under 200ms.

4fill in blank

hard

Fill both blanks to check if the response JSON has a 'status' key equal to 'success'.

Postman

pm.test('Status is success', function () { pm.expect(pm.response.json()).to.have.[1]('status').that.[2]('success'); });

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

Aproperty

Bequal

Cequals

Dcontain

Attempts:

💡 Hint

Common Mistakes

Using 'contain' instead of 'equal' for exact match.

'property' checks the key exists, and 'equal' checks its value matches 'success'.

5fill in blank

hard

Fill all three blanks to validate the response JSON array length is greater than 0 and contains the key 'id'.

Postman

pm.test('Response array valid', function () { const data = pm.response.json(); pm.expect(data.length).to.be.[1](0); pm.expect(data[0]).to.have.[2]([3]); });

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

Aabove

Bproperty

C'id'

Dbelow

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'below' instead of 'above' for length check.

'above' checks length > 0, 'property' checks key exists, and 'id' is the key name.
