What APIs are and why testing them matters in Postman - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to send a GET request to an API endpoint using Postman scripting.

Postman

pm.sendRequest('[1]', function (err, res) {
    pm.test('Status code is 200', function () {
        pm.expect(res.code).to.eql(200);
    });
});

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

Apm.response.to.have.status(200)

Bhttps://api.example.com/data

Cpm.expect(200).to.eql(res.code)

Dconsole.log('Hello World')

💡 Hint

Common Mistakes

Using assertion code instead of the URL in pm.sendRequest

Putting console.log inside pm.sendRequest URL argument

The URL string is required to send a GET request to the API endpoint. Other options are either code snippets for assertions or logging, not URLs.

2fill in blank

medium

Complete the code to check if the API response body contains the key 'success' set to true.

Postman

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

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

Bstatus

Cerror

Dmessage

💡 Hint

Common Mistakes

Using 'status' or 'error' instead of 'success' key

Trying to compare the whole response instead of the key

The key 'success' is expected in the response JSON to be true. Other keys are common but not the target here.

3fill in blank

hard

Fix the error in the assertion to correctly check the response status code is 404.

Postman

pm.test('Status code is 404', function () {
    pm.expect(pm.response.code).[1](404);
});

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

Ato.eql

Bto.equal

Cto.be.eql

Dto.be.equal

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'to.equal' which is not valid in this context

Adding extra 'be' causing syntax errors

The correct Chai assertion method is 'to.eql' to check equality. Other options are invalid or incorrect syntax.

4fill in blank

hard

Fill both blanks to create a test that checks the response time is less than 200 milliseconds.

Postman

pm.test('Response time is fast', function () {
    pm.expect(pm.response.[1]).to.be.[2](200);
});

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

AresponseTime

Bstatus

Cbelow

Dabove

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'status' instead of 'responseTime' for the property

Using 'above' instead of 'below' for the assertion

'pm.response.responseTime' gives the response time in ms, and 'to.be.below' checks if it is less than the given value.

5fill in blank

hard

Fill all three blanks to write a test that verifies the response JSON has a 'data' array with length greater than 0.

Postman

pm.test('Data array is not empty', function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData.[1]).to.be.an('array').that.[2].length.[3](0);
});

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

Adata

Bhas

Cabove

Dincludes

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'includes' instead of 'has' for property assertion

Using 'below' instead of 'above' for length check

'data' is the key for the array, 'has' is used to assert property existence, and 'above' checks length greater than 0.
