Postman Interview Questions and Answers
Question - 81 : - In Postman, how will you create random integers in a particular range?
Answer - 81 : -
If you want to create numbers in the range of 1 to N, you can do so as follows in the pre-request script:
pm.globals.set('randomnumber, Math.floor (Math.random() N));
We can then utilise this variable in the URL as
{{randomNumber}}
Question - 82 : - In Postman, what is digest auth?
Answer - 82 : -
Postman provides the Digest Authorisation method as one of its authorization options. The client sends the request to the API first, and the server responds with a number that can only be used once a realm value and a 401 unauthorised response code. After that, we'll receive an encrypted data array including both the username and password and the previously obtained data from the server. The server generates an encrypted data string from this information and compares it to what was sent to authenticate the request.
This can be done by going to the Authorization tab and selecting "Digest Auth" from the drop-down menu. The fields for both stages of the authentication request are displayed in the Postman window. Based on the data received from the server, the fields required for the second step of the request are auto-filled.

Question - 86 : - Postman accepts authorisation credentials in which types of encoding?
Answer - 86 : -
The only codec supported by Postman is Base64. This is built-in to Postman, or you can use third-party websites to convert your credentials to base64.
Question - 87 : - Why does Postman only allow Base64 encoding?
Answer - 87 : -
We utilise base64 because it converts data into text and sends it more straightforwardly, such as HTML form data. We can also rely on the same 64 characters in any encoding language.
Question - 88 : - In Postman, may global scope variables have duplicate names?
Answer - 88 : -
