API Testing with Postman - Testing PUT Calls

The video tutorial explains the concept of PUT calls in API testing, highlighting their purpose of editing existing objects rather than creating new ones, as is the case with POST calls. It discusses the importance of understanding which fields can be modified, using a sample application to demonstrate the process. The tutorial also covers how changes to associated data, like comments, propagate through the system. Additionally, it touches on security considerations, such as handling unauthorized access and the implications of returning specific error codes. The video encourages further exploration of PUT request testing.

What is the primary purpose of a PUT call in API testing?

• To edit an existing object

• To delete an existing object

• To create a new object

• To retrieve data from the server

Why is it important to restrict changes to the ID field in a database?

• To enhance data encryption

• To maintain data integrity and reference consistency

• To prevent unauthorized data access

• To allow easy data retrieval

In the practical example, what happens when you try to change the ID of a blog post using a PUT call?

• The ID change is ignored

• The request fails with an error

• The entire blog post is deleted

• The ID is successfully changed

What is the effect of modifying a comment associated with a blog post?

• The changes propagate to the associated blog post

• The blog post is archived

• The changes do not affect the blog post

• The comment is deleted

What HTTP status code is typically returned when a user is unauthorized to modify a resource?

• 200 OK

• 500 Internal Server Error

• 401 Unauthorized

• 404 Not Found

Why might returning a 404 error be more secure than a 401 error in some cases?

• It is easier to implement

• It hides the existence of the resource

• It is the standard practice for all errors

• It provides more information to the user

What should be considered when performing PUT calls on resources that a user is not authenticated for?

• Ensuring the user receives a 401 or 404 error

• Logging the user out of the system

• Returning a 200 OK status

• Allowing the changes to go through
