Reusable test scripts in Postman - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are reusable test scripts in Postman?

Reusable test scripts are pieces of code written once and used multiple times across different API requests or collections to avoid repetition and maintain consistency.

How can you create reusable test scripts in Postman?

You can create reusable test scripts by writing them in the Collection or Folder 'Tests' tab, or by using the 'Pre-request Script' or 'Tests' tabs and calling them via the 'pm' API in individual requests.

beginner

Why is using reusable test scripts beneficial?

Reusable test scripts save time, reduce errors, and make maintenance easier because you update the script once and it applies everywhere it is used.

What is an example of a reusable test script in Postman?

A reusable test script could check if the response status code is 200 and if the response time is less than 500ms. This script can be placed in a collection to run for all requests.

How do environment and global variables help in reusable test scripts?

Environment and global variables allow reusable scripts to work dynamically by using variable values that can change per environment or globally, making scripts flexible and adaptable.

Where can you place reusable test scripts in Postman?

A In the Postman console

B Only inside individual requests

C In the Postman settings

D In the Collection or Folder 'Tests' tab

Reusable test scripts are best placed in the Collection or Folder 'Tests' tab to apply them to multiple requests.

What is a key benefit of reusable test scripts?

A They reduce code duplication and ease maintenance

B They increase test execution time

C They require rewriting for each request

D They only work with one API endpoint

Reusable test scripts reduce code duplication and make maintenance easier by centralizing common test logic.

Which Postman feature helps make reusable scripts dynamic across environments?

A Request headers

B Postman console logs

C Global and environment variables

D Response body

Global and environment variables allow reusable scripts to adapt to different environments dynamically.

How do you call reusable test scripts in individual requests?

A By copying and pasting the code manually

B By using the pm API and placing scripts in Collection or Folder tests

C By exporting the script as a file

D By running Postman in debug mode

Reusable scripts are placed in Collection or Folder tests and automatically run for requests inside them using the pm API.

What does a reusable test script typically check?

A Response status, response time, and response body structure

B Only the request URL

C The Postman app version

D The user's computer specs

Reusable test scripts commonly check response status codes, response times, and response body structure to validate API behavior.
