Practice - 5 Tasks

1fill in blank

easy

Complete the code to insert the base URL variable in the request URL.

Postman

pm.sendRequest(`$[1]/users`, function (err, res) {
    pm.expect(err).to.be.null;
    pm.expect(res).to.have.property('code', 200);
});

💡 Hint

Common Mistakes

Using pm.variables.get() instead of pm.environment.get() for environment variables.

Using pm.request.url which is the current request URL, not the base URL.

Trying to get the URL from the response.

The base URL is stored as an environment variable. Use pm.environment.get('baseUrl') to retrieve it dynamically.

medium

Complete the code to build a dynamic URL with a user ID path parameter.

Postman

const userId = pm.environment.get('userId');
const url = `$[1]/users/${userId}`;
pm.sendRequest(url, function (err, res) {
    pm.expect(res).to.have.property('code', 200);
});

💡 Hint

Common Mistakes

Using pm.variables.get('userId') for the base URL instead of userId variable.

Using pm.request.url which is the current request URL, not the base URL.

Not using template literals correctly.

To build the full URL, get the base URL from environment variables using pm.environment.get('baseUrl').

hard

Fix the error in the code to correctly append query parameters to the URL.

Postman

const baseUrl = pm.environment.get('baseUrl');
const params = new URLSearchParams();
params.append('status', 'active');
const url = baseUrl + '/users?[1]';
pm.sendRequest(url, function (err, res) {
    pm.expect(res).to.have.property('code', 200);
});

💡 Hint

Common Mistakes

Appending the params object directly without converting to string.

Using params.append() which adds parameters but does not return a string.

Using params.get() which retrieves a value, not the whole query string.

Use params.toString() to convert the URLSearchParams object to a query string.

4fill in blank

hard

Fill both blanks to build a URL with multiple query parameters dynamically.

Postman

const baseUrl = pm.environment.get('baseUrl');
const params = new URLSearchParams();
params.append('status', 'active');
params.append('role', [1]);
const url = baseUrl + '/users?[2]';
pm.sendRequest(url, function (err, res) {
    pm.expect(res).to.have.property('code', 200);
});

💡 Hint

Common Mistakes

Using params object directly in the URL without converting to string.

Not quoting the role value string.

Using params instead of params.toString() for the URL.

Use a string like 'admin' for the role parameter and convert params to string for the URL.

5fill in blank

hard

Fill all three blanks to build a dynamic URL with path and query parameters.

Postman

const baseUrl = pm.environment.get([1]);
const userId = pm.environment.get('userId');
const params = new URLSearchParams();
params.append('active', [2]);
const url = `${baseUrl}/users/$[3]?${params.toString()}`;
pm.sendRequest(url, function (err, res) {
    pm.expect(res).to.have.property('code', 200);
});

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

A'baseUrl'

B'true'

CuserId

D'userId'

💡 Hint

Common Mistakes

Not quoting the environment variable name in get().

Using boolean true instead of string 'true' for query parameter.

Using string 'userId' instead of variable userId for path.

Get the base URL from environment variable 'baseUrl', use string 'true' for active, and use the userId variable for the path.
