Condition block in Postman - Cheat Sheet & Quick Revision

Recall & Review

What is a Condition block in Postman tests?

A Condition block is a part of the test script where you check if something is true or false, like checking if a response status is 200. It helps decide what to do next based on the result.

How do you write a simple condition block to check if the response status is 200 in Postman?

Use an if statement like:

if (pm.response.code === 200) { pm.test('Status is 200', () => { pm.expect(pm.response.code).to.equal(200); }); }

beginner

Why are condition blocks useful in Postman tests?

They let you run tests only when certain things happen, like testing a feature only if the previous request succeeded. This saves time and makes tests smarter.

beginner

What happens if the condition in a Postman condition block is false?

The code inside the block does not run. This means the test inside won’t execute, so you can control which tests run based on conditions.

Show an example of using an else block in Postman test scripts.

Example:

if (pm.response.code === 200) { pm.test('Success', () => { pm.expect(true).to.be.true; }); } else { pm.test('Failure', () => { pm.expect.fail('Response was not 200'); }); }

What does a condition block in Postman test scripts do?

A Runs code only if a condition is true

B Runs code regardless of any condition

C Deletes the response data

D Sends a new request automatically

A condition block runs the code inside it only when the condition is true, helping control test flow.

Which JavaScript keyword is used to start a condition block in Postman tests?

A if

B for

C while

D switch

The 'if' keyword starts a condition block to check if a condition is true.

What will happen if the condition in an if block is false in Postman test scripts?

A The test always passes

B The code inside the block runs

C Postman crashes

D The code inside the block does not run

If the condition is false, the code inside the if block does not run.

How can you test for a response status of 200 using a condition block in Postman?

A pm.test('Status is 200')

B if (pm.response.code === 200) { pm.test(...) }

C pm.response.code = 200

D pm.expect(200).to.equal(pm.response.code)

Using if (pm.response.code === 200) lets you run tests only when the status is 200.

What is the purpose of an else block in Postman test scripts?

A To stop the test execution

B To repeat the if block

C To run code when the if condition is false

D To send another request

An else block runs code when the if condition is false, allowing alternative actions.

Explain how a condition block works in Postman test scripts and why it is useful.

Think about checking response status before running tests.

Write a simple Postman test script using a condition block to check if the response status is 200 and explain each part.

Start with if, then pm.test inside, then pm.expect to check status.
