Complete the code to specify the HTTP method for retrieving data from a REST API.

Postman

pm.sendRequest({ url: 'https://api.example.com/data', method: '[1]' }, function (err, res) { pm.test('Status code is 200', function () { pm.expect(res.code).to.equal(200); }); });

💡 Hint

Common Mistakes

Using POST instead of GET for retrieving data.

The GET method is used to retrieve data from a REST API. Other methods like POST, PUT, and DELETE are used for creating, updating, or deleting data.

Complete the code to check if the response body contains the expected JSON key.

Postman

pm.test('Response has userId', function () { var jsonData = pm.response.json(); pm.expect(jsonData).to.have.property('[1]'); });

💡 Hint

Common Mistakes

Checking for keys that are not present in the response.

The test checks if the JSON response contains the key 'userId'. This is common in REST API responses to identify the user.

Fix the error in the assertion to correctly check the response status code.

Postman

pm.test('Status code is 201', function () { pm.expect(pm.response.[1]).to.eql(201); });

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

Bstatus

CstatusCode

DresponseCode

💡 Hint

Common Mistakes

Using incorrect property names like status or statusCode.

In Postman tests, the correct property to check the status code is pm.response.code. Using other properties will cause errors or fail the test.

4fill in blank

hard

Fill both blanks to create a test that checks if the response time is less than 500 milliseconds.

Postman

pm.test('Response time is fast', function () { pm.expect(pm.response.[1]).to.be.[2](500); });

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

💡 Hint

Common Mistakes

Using 'above' instead of 'below' for checking response time.

The property pm.response.responseTime gives the response time in milliseconds. The assertion to.be.below(500) checks if it is less than 500 ms.

5fill in blank

hard

Fill all three blanks to write a test that verifies the response header 'Content-Type' is 'application/json'.

Postman

pm.test('Content-Type is JSON', function () { pm.expect(pm.response.headers.get('[1]')).to.equal('[2]/[3]'); });

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

AContent-Type

Bapplication

Cjson

Dcontent-type

Attempts:

💡 Hint

Common Mistakes

Using lowercase header name or wrong content type value.

The header name is 'Content-Type' (case sensitive in Postman). The expected value is 'application/json' which indicates JSON data format.
