💡 Hint

Common Mistakes

Using a wrong header name like 'Authorization' or 'Accept'.

Misspelling the header name or using lowercase.

The header name to check is 'Content-Type'. This assertion verifies the response includes this header.

2fill in blank

medium

Complete the code to assert the 'Content-Type' header value equals 'application/json'.

Postman

pm.test('Content-Type is application/json', function () {
    pm.response.to.have.header('Content-Type', [1]);
});

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

A'application/json'

C'application/xml'

D'text/plain'

💡 Hint

Common Mistakes

Using incorrect content types like 'text/html' or 'application/xml'.

Forgetting to put quotes around the string value.

The assertion checks that the 'Content-Type' header value is exactly 'application/json'.

3fill in blank

hard

Complete the code to assert the 'Cache-Control' header equals 'no-cache'.

Postman

pm.test('Cache-Control equals no-cache', function () {
    pm.response.to.have.header('Cache-Control', [1]);
});

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

A'public'

B'no-store'

C'no-cache'

D'max-age=3600'

💡 Hint

Common Mistakes

Using wrong cache directives like 'no-store' or 'public'.

Missing quotes around the string value.

The assertion must check that the 'Cache-Control' header contains the value 'no-cache'.

4fill in blank

hard

Fill both blanks to assert the response header 'Authorization' exists and its value is 'Bearer token123'.

Postman

pm.test('Authorization header check', function () {
    pm.response.to.have.header('[1]');
    pm.expect(pm.response.headers.get('[2]')).to.eql('Bearer token123');
});

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

DCache-Control

💡 Hint

Common Mistakes

Using different header names in the two blanks.

Checking a wrong header like 'Content-Type' instead of 'Authorization'.

Both blanks require the header name 'Authorization' to check its presence and value.

5fill in blank

hard

Fill all three blanks to assert the response header 'Content-Type' exists and its value is 'application/json'.

Postman

pm.test('Content-Type header presence and value', function () {
    pm.response.to.have.header('[1]');
    pm.expect(pm.response.headers.get('[2]')).to.eql('[3]');
});

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

AContent-Type

BCache-Control

Capplication/json

Dno-store

Attempts:

💡 Hint

Common Mistakes

Mixing header names between blanks.

Using wrong expected values like 'no-store' for 'Content-Type'.

The first blank is the header name to check presence ('Content-Type'). The second blank is the header name to get value ('Content-Type'). The third blank is the expected value ('application/json').
