Practice - 5 Tasks

easy

Complete the code to send a GET request to check API status.

Postman

pm.sendRequest({ url: '[1]', method: 'GET' }, function (err, res) { pm.expect(res).to.have.status(200); });

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

Ahttps://api.example.com/status

Bapi.example.com/status

Chttps://api.example.com

DGET https://api.example.com/status

💡 Hint

Common Mistakes

Omitting https:// causes request failure

Using method name inside URL

The full URL with protocol is required to send a proper GET request in Postman scripts.

medium

Complete the code to check if the API response time is less than 200ms.

Postman

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

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

💡 Hint

Common Mistakes

Using 'above' checks for greater than

Using 'equal' checks for exact match

We want to ensure the response time is below 200 milliseconds for good API health.

3fill in blank

hard

Fix the error in the test that checks if the response body contains the key 'status'.

Postman

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

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

💡 Hint

Common Mistakes

Using 'contain' or 'include' works for strings or arrays, not object keys

Using 'haveKey' is not a valid Chai method

The correct Chai assertion to check for an object key is 'property'.

4fill in blank

hard

Fill both blanks to create a test that checks if the API response status is 200 and the response time is less than 300ms.

Postman

pm.test('API health check', function () { pm.expect(pm.response).to.have.status([1]); pm.expect(pm.response.responseTime).to.be.[2](300); });

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

💡 Hint

Common Mistakes

Using 404 status code means not found error

Using 'above' checks for longer response time

Status code 200 means success, and response time below 300ms means good performance.

5fill in blank

hard

Fill all three blanks to write a test that verifies the response JSON has a 'status' key with value 'ok' and response time less than 250ms.

Postman

pm.test('Complete API health check', function () { const jsonData = pm.response.json(); pm.expect(jsonData).to.have.[1]('status'); pm.expect(jsonData.status).to.eql([2]); pm.expect(pm.response.responseTime).to.be.[3](250); });

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

B'ok'

Cbelow

D'OK'

Attempts:

💡 Hint

Common Mistakes

Using 'OK' instead of 'ok' causes test failure

Using 'include' instead of 'property' for key check

Check the JSON has 'status' key, its value equals 'ok' (case sensitive), and response time is below 250ms.
