Using 'CacheControl' without hyphen as header key.

Using 'no-store' instead of 'no-cache' as header value.

The header key must be 'Cache-Control' and the value 'no-cache' to disable caching.

5fill in blank

hard

Fill all three blanks to create a test that checks if the 'User-Agent' header contains 'PostmanRuntime'.

Postman

pm.test('User-Agent contains PostmanRuntime', () => {
  const userAgent = pm.request.headers.get('[1]');
  pm.expect(userAgent).to.include('[2]');
  pm.expect(typeof userAgent).to.eql('[3]');
});

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

💡 Hint

Common Mistakes

Using lowercase 'user-agent' which may not match the header key.

Checking for wrong substring in the header value.

Using wrong type in the typeof check.

The header key is 'User-Agent', the value to check is 'PostmanRuntime', and the type of the header value is 'string'.
