Postman Interview Questions and Answers
Question - 71 : - Is it possible to reuse the authentication token for multiple requests?
Answer - 71 : -
Yes, it is possible to reuse the authentication token for multiple requests. We can achieve it by creating a collection and adding all the requests having the same authentication token to that collection and then assigning the auth token to the same collection. We can apply it to the individual requests by selecting the "Inherit auth from parent" option in the Authorization tab.
Question - 72 : - In POST methods, what is a binary form?
Answer - 72 : -
The binary form is intended to assist in transmitting data in a format that cannot be entered manually. These options are used for submitting large files in a POST request, such as photos, CSV files, etc. The most straightforward encoding for sending complex data with the request is binary.
Question - 73 : - Why does Postman mostly use Base64 encoding?
Answer - 73 : -
Base64 encoding is widely used because it allows data to be transmitted in a textual format that is easier to send in HTML form statistics requests. Another reason we utilise this is that encoding with identical 64 characters is quite reliable in any language.
Question - 74 : - Why is the 304 status code used?
Answer - 74 : -
NOT MODIFIED is the 304 status code. In the case of limited GET queries, this is used to reduce the network's bandwidth. In such circumstances, the response body should be empty or blank, and the headers should include information such as the date, location, and signature, among other things.
Question - 75 : - Why isn't it preferable to save work on the Postman cloud?
Answer - 75 : -
Because of the required privacy and security, it is not recommended that we store our work on the Postman cloud when working on enterprise-level applications for enterprises. A skilled hacker has the potential to compromise the security of the Postman cloud.
Question - 76 : - What are the different variable scopes that Postman offers?
Answer - 76 : -
The following variable scopes are available in Postman:
- Global Variables: Global variables allow data to be shared between many collections, requests, and scripts. They can be found all over the office.
- Environment Variables: These allow us to customise requests for various development settings, such as local testing, stage testing, and production testing.
- Local Variables: These are temporary variables that request scripts can only access. Depending on the needs, they are either limited to a single request or a single collection. These variables are no longer available after the script has finished running.
- Variables in a Collection: These variables are set to be available for all requests in the collection. They are unaffected by their surroundings.
- Data Variables: These variables come from external JSON or CSV files that define the datasets that Collection Runner or Newman needs to conduct the collection.
Question - 77 : - Can the authentication token be reused for many requests?
Answer - 77 : -
Yes, it's conceivable. It is possible to create a collection, add all requests with the same authentication token, and then assign the authentication token to the collection. Select the "Inherit auth from parent" option on the Authorization tab to apply this to individual requests.
Question - 78 : - What are Postman workspaces? And what purpose do they serve?
Answer - 78 : -
Workspaces are Postman-provided areas/spaces for teams to collaborate on a specific set of collections. It allows you to logically divide requests or collections exclusive to a developer or team, making request administration accessible.
In Postman, there are two sorts of workspaces:
- Personal Workspace: These workspaces are essential when working on many projects simultaneously and need logical separation between requests to handle them better.
- Team Workspace: These are designed for group collaboration so that multiple people can participate in testing requests.
By publishing the users' email addresses, we can encourage new users to collaborate on our collections. After accepting the invitation, new users can begin contributing to the workspace by adding or changing requests.
Question - 79 : - What is ScratchPad?
Answer - 79 : -
Scratch Pad is a Postman-provided workspace that allows us to operate without relying on Postman servers. It allows you to use some of Postman's capabilities when you're not connected to the internet. The features include creating collections, creating requests, and submitting requests. These are saved locally, and the work is saved into the workspace once you log in.
Question - 80 : - Does Postman give you the option of using the command line?
Answer - 80 : -
Postman supplies the Newman command-line tool, which can be used to run any Postman collection. It's a NodeJS-based package that uses Newman Collection Runner to execute collections. It is fully compatible with Postman's Collection Runner, which means it may run assertions, pre-request scripts, and other request scripts tied to the collection's requests.
Newman can be used by following the procedures below:
- Setup Node
- Using the npm command, install the Newman package as follows: npm install -g newman
- Open Postman and export the environment to JSON format to run the collection. Then use the following command in Newman to run the collection:
newman run {{path to collection json}} -e {{path to environment json}}
