API Testing with Postman - Testing POST Calls

The video tutorial explores hands-on API testing, focusing on post calls. It begins with an introduction to API testing, highlighting the transition from static to dynamic data. The tutorial demonstrates testing post calls using a local application, emphasizing the importance of parameters and ID management. It further explores handling invalid inputs, such as duplicate IDs and null values, and their impact on API functionality. The video concludes with a summary of post call testing and introduces the next topic: testing put calls.

What is the main focus of this section on API testing?

• User interface testing

• Data modification through post, put, and delete calls

• Database management

• Static data retrieval

What are the two main ways users can harm an app through post calls?

• Malicious users and accidental errors

• Network failures and server overload

• Incorrect API documentation and outdated software

• Poor user interface and lack of training

What happens if a post request is sent with a duplicate ID?

• The request is ignored

• The existing data is overwritten

• A new entry is created with a different ID

• An error is returned indicating a duplicate ID

Why is it important to test post requests for missing fields?

• To improve the speed of the API

• To prevent the creation of incomplete data entries

• To reduce the size of the database

• To ensure the API can handle any input

What is the result of sending a post request with an ID larger than the maximum double value?

• The ID is automatically adjusted

• The ID is set to null

• The request fails with an error

• The request is ignored

Why is it important to test for invalid inputs in API testing?

• To simplify the codebase

• To reduce the cost of development

• To make the API faster

• To ensure the API can handle unexpected scenarios

What should be considered when testing an API besides handling invalid inputs?

• Network latency

• Database schema

• User interface design

• Security and performance
