Response time assertions in Postman - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to assert the response time is less than 200 milliseconds.

Postman

pm.test('Response time is less than 200ms', function () {
    pm.expect(pm.response.responseTime).to.be.[1](200);
});

💡 Hint

Common Mistakes

Using 'above' instead of 'lessThan' causes the test to check for greater response times.

Using 'equal' will fail if response time is not exactly 200ms.

The lessThan assertion checks that the response time is less than the given value.

2fill in blank

medium

Complete the code to assert the response time is at most 500 milliseconds.

Postman

pm.test('Response time is at most 500ms', function () {
    pm.expect(pm.response.responseTime).to.be.[1](500);
});

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

💡 Hint

Common Mistakes

Using 'above' will check for greater values, which is incorrect here.

Using 'equal' will fail if response time is not exactly 500ms.

The below assertion checks that the response time is less than the given value.

3fill in blank

hard

Fix the error in the assertion to correctly check response time is less than 300 milliseconds.

Postman

pm.test('Response time check', function () {
    pm.expect(pm.response.responseTime).to.be.[1](300);
});

💡 Hint

Common Mistakes

Using 'less' causes a syntax error because it is not a valid method.

Using 'greaterThan' checks the opposite condition.

The correct Chai assertion method is lessThan to check if the value is less than 300.

4fill in blank

hard

Fill both blanks to assert response time is between 100 and 400 milliseconds.

Postman

pm.test('Response time is between 100 and 400ms', function () {
    pm.expect(pm.response.responseTime).to.be.[1](400);
    pm.expect(pm.response.responseTime).to.be.[2](100);
});

💡 Hint

Common Mistakes

Using 'above' instead of 'greaterThan' causes confusion.

Using 'lessThan' instead of 'below' is valid but inconsistent here.

Use below to check less than 400 and greaterThan to check more than 100.

5fill in blank

hard

Fill all three blanks to assert response time is less than 250ms, greater than 50ms, and not equal to 100ms.

Postman

pm.test('Complex response time assertions', function () {
    pm.expect(pm.response.responseTime).to.be.[1](250);
    pm.expect(pm.response.responseTime).to.be.[2](50);
    pm.expect(pm.response.responseTime).to.not.be.[3](100);
});

💡 Hint

Common Mistakes

Using 'below' instead of 'lessThan' for the first blank causes inconsistency.

For the last blank, forgetting 'not.be' causes the test to check equality instead of inequality.

Use lessThan for less than 250ms, greaterThan for more than 50ms, and equal with not.be to assert not equal to 100ms.
