Why chaining simulates real workflows in Postman - Test Your Understanding

Practice - 5 Tasks

Complete the code to set the environment variable with the response value.

Postman

pm.environment.set('userId', [1]);

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

Apm.request.url

Bpm.response.text()

Cpm.response.json().id

Dpm.environment.get('userId')

💡 Hint

Common Mistakes

Using pm.response.text() returns raw text, not parsed JSON.

Trying to get variable from environment instead of response.

The correct way to get a value from the JSON response is using pm.response.json().id. This sets the environment variable userId for chaining.

Complete the code to use the environment variable in the next request URL.

Postman

pm.request.url = `https://api.example.com/users/$[1]`;

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

Apm.environment.get('userId')

Bpm.response.json().id

Cpm.variables.get('userId')

Dpm.request.body

💡 Hint

Common Mistakes

Using pm.response.json() here is wrong because this is a new request.

Using pm.variables.get() may not access environment variables.

To use the stored variable in the request URL, use pm.environment.get('userId') which retrieves the value set earlier.

Fix the error in the test script to correctly check the response status code.

Postman

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

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

A200

B"200"

Cpm.response.code

D'200'

💡 Hint

Common Mistakes

Using '200' or "200" as string causes assertion failure.

Using pm.response.code is not valid here.

The status code should be a number, so 200 without quotes is correct. Using quotes makes it a string, causing the test to fail.

4fill in blank

hard

Fill both blanks to extract 'token' from response and set it as a global variable.

Postman

const token = pm.response.json().[1];
pm.globals.set('[2]', token);

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

Atoken

BauthToken

CaccessToken

💡 Hint

Common Mistakes

Using wrong property name like 'id' or 'accessToken'.

Setting environment variable instead of global.

The response JSON property is 'token', and the global variable name to set is 'authToken'. This allows chaining with a global token.

5fill in blank

hard

Fill all three blanks to create a test that checks if the response JSON has a 'success' property set to true.

Postman

pm.test('Response success is true', function () {
  const jsonData = pm.response.[1]();
  pm.expect(jsonData.[2]).to.eql([3]);
});

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

Ajson

Bsuccess

Ctrue

Dtext

Attempts:

3 left

💡 Hint

Common Mistakes

Using pm.response.text() returns string, not JSON.

Checking 'success' as string 'true' instead of boolean true.

Use pm.response.json() to parse JSON, check the 'success' property, and expect it to equal true (boolean).
