Output block in Postman - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to log the response status code in Postman test script.

Postman

pm.test("Status code is 200", function () {
    pm.expect(pm.response.[1]).to.eql(200);
});

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

💡 Hint

Common Mistakes

Using pm.response.status instead of pm.response.code

Trying to access pm.response.body for status code

The pm.response.code property holds the HTTP status code of the response. Using it in the test checks if the status is 200.

Complete the code to check if the response body contains the string 'success'.

Postman

pm.test("Body contains success", function () {
    pm.expect(pm.response.text().[1]("success")).to.be.true;
});

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

💡 Hint

Common Mistakes

Using indexOf which returns a number, not a boolean

Using match which returns an array or null

The includes method returns true if the string contains the given substring.

Fix the error in the code to correctly parse JSON response and check a property.

Postman

pm.test("Check user id", function () {
    let jsonData = pm.response.[1]();
    pm.expect(jsonData.userId).to.eql(1);
});

💡 Hint

Common Mistakes

Using pm.response.text() which returns a string, not an object

Trying to access pm.response.body() which is not a method

The pm.response.json() method parses the response body as JSON and returns an object.

4fill in blank

hard

Fill both blanks to check if the response header 'Content-Type' is 'application/json'.

Postman

pm.test("Content-Type is JSON", function () {
    pm.expect(pm.response.[1].get([2])).to.eql('application/json');
});

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

Aheaders

B"Content-Type"

C"content-type"

Dbody

Attempts:

💡 Hint

Common Mistakes

Using pm.response.body instead of headers

Not quoting the header name string

The pm.response.headers.get() method retrieves the value of a header by name. Header names are case-insensitive but usually written as 'Content-Type'.

5fill in blank

hard

Fill all three blanks to create a test that checks if the response time is less than 200ms.

Postman

pm.test("Response time is fast", function () {
    pm.expect(pm.response.[1]).to.be.[2]([3]);
});

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

AresponseTime

Bbelow

C200

Dabove

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'above' instead of 'below' for less than check

Not using the correct property name for response time

The pm.response.responseTime gives the response time in milliseconds. The assertion to.be.below(200) checks if it is less than 200ms.

Practice

1. What does the Output block in Postman primarily display after running a request?

easy

A. The list of saved environments

B. The raw API request headers only

C. The Postman app settings and preferences

D. The results of test scripts and any console logs

Solution

1. Step 1: Understand the purpose of the Output block

   The Output block shows what happened after running a request, including test results and logs.

2. Step 2: Identify what is NOT shown in the Output block

   Settings, environments, or just headers are not shown here; only test results and logs appear.

3. Final Answer:

   The results of test scripts and any console logs -> Option D

4. Quick Check:

   Output block = test results + logs [OK]

Hint: Output block shows test results and logs only [OK]

Common Mistakes:

• Confusing Output block with environment settings
• Thinking it shows only request headers
• Assuming it displays saved collections

2. Which of the following is the correct way to log a message to the Output block in a Postman test script?

easy

A. log('Test passed')

B. print('Test passed')

C. console.log('Test passed')

D. echo('Test passed')

Solution

1. Step 1: Recall JavaScript logging syntax in Postman

   Postman test scripts use JavaScript, and console.log() is the standard way to log messages.

2. Step 2: Identify incorrect logging functions

   Functions like print(), log(), and echo() are not valid in Postman scripts.

3. Final Answer:

   console.log('Test passed') -> Option C

4. Quick Check:

   Use console.log() to log messages [OK]

Hint: Use console.log() to print messages in Output block [OK]

Common Mistakes:

• Using print() instead of console.log()
• Trying to use echo() which is not JavaScript
• Forgetting parentheses in console.log

3. Given this Postman test script:

pm.test('Status code is 200', () => {
    pm.response.to.have.status(200);
});
console.log('Test completed');

What will you see in the Output block after running the request if the response status is 200?

medium

A. Test failed and no message

B. Test passed and 'Test completed' message

C. Only 'Test completed' message

D. No output at all

Solution

1. Step 1: Analyze the test script behavior

   The test checks if the response status is 200. If true, the test passes.

2. Step 2: Understand console.log output

   The console.log prints 'Test completed' regardless of test result.

3. Final Answer:

   Test passed and 'Test completed' message -> Option B

4. Quick Check:

   Passing test + console.log message = Test passed and 'Test completed' message [OK]

Hint: Passing test shows pass + console.log output [OK]

Common Mistakes:

• Assuming console.log only shows on failure
• Thinking test fails if console.log runs
• Ignoring test result messages

4. You wrote this Postman test script:

pm.test('Response time is less than 200ms', () => {
    pm.expect(pm.response.responseTime).to.be.below(200);
});
console.log('Check complete');

But after running, the Output block shows no test results or logs. What is the most likely problem?

medium

A. The test script is not saved or attached to the request

B. The response time is exactly 200ms, so test is skipped

C. console.log is not supported in Postman

D. The Output block only shows errors, not passes

Solution

1. Step 1: Check why Output block is empty

   If no test results or logs appear, the script might not be running at all.

2. Step 2: Confirm script attachment and saving

   Scripts must be saved and attached to the request to run and show output.

3. Final Answer:

   The test script is not saved or attached to the request -> Option A

4. Quick Check:

   Unsaved script = no output [OK]

Hint: Always save and attach test scripts to see output [OK]

Common Mistakes:

• Thinking console.log is unsupported
• Assuming Output block hides passing tests
• Believing test skips on exact boundary values

5. You want to verify in Postman that a JSON response contains a key userId with value 5, and log 'User verified' only if the test passes. Which test script will correctly show this in the Output block?

hard

A. pm.test('UserId is 5', () => {
pm.expect(pm.response.json().userId).to.eql(5);
});
if(pm.response.json().userId === 5) console.log('User verified');

B. pm.test('UserId is 5', () => {
pm.expect(pm.response.json().userId).to.eql(5);
console.log('User verified');
});

C. if(pm.response.json().userId === 5) {
pm.test('UserId is 5', () => {});
console.log('User verified');
}

D. pm.test('UserId is 5', () => {
pm.expect(pm.response.json().userId).to.eql(5);
});
console.log('User verified');

Solution

1. Step 1: Understand conditional logging requirement

   pm.test callbacks always execute fully; assertions don't halt execution. Log only on pass requires a matching condition.

2. Step 2: Analyze options

   A: unconditional log after test - always logs.
   B: log inside pm.test - executes even if assertion fails.
   C: empty pm.test - no proper verification.
   D: proper assertion test + matching if condition - logs only if userId === 5 (test passes).

3. Final Answer:

   pm.test('UserId is 5', () => { pm.expect(pm.response.json().userId).to.eql(5); }); if(pm.response.json().userId === 5) console.log('User verified'); -> Option A

4. Quick Check:

   if() matching test condition = log only on pass [OK]

Hint: Use if() matching assertion after pm.test for log only on pass [OK]

Common Mistakes:

• Putting console.log inside pm.test (runs on fail too)
• Logging unconditionally outside pm.test
• Using empty pm.test callback
