REST API Automation Testing from Scratch - REST Assured Java - Path, Query Parameters, and Headers in REST API

The video tutorial covers the basics of REST APIs, emphasizing the importance of understanding theoretical concepts before practical application. It explains resources, base URLs, and the role of path and query parameters in API requests. An example using Google search illustrates query parameters. The tutorial also discusses headers and cookies as metadata in API requests. Finally, it introduces the Postman tool for manual API testing, setting the stage for future lessons on automated testing.

Why is it important to understand theoretical concepts before moving to practical examples in REST API testing?

• To save time during practical sessions

• To make theoretical knowledge redundant

• To ensure a strong foundation for understanding API behavior

• To avoid learning practical skills

What is a resource in the context of REST APIs?

• A programming language

• A collection of APIs or a specific API endpoint

• A type of server

• A database

What is the role of a base URL in REST APIs?

• It is used for user authentication

• It is a type of query parameter

• It specifies the server where APIs are hosted

• It defines the data format

How do path parameters differ from query parameters in API requests?

• Path parameters are used for sorting data

• Query parameters are used to specify sub-resources

• Path parameters identify specific resources within a collection

• Query parameters are mandatory in all API requests

What symbol is used to identify query parameters in a URL?

• A colon (:)

• A slash (/)

• A question mark (?)

• An ampersand (&)

In the context of API requests, what is the purpose of headers?

• To define the server location

• To provide additional metadata for the request

• To store user data

• To encrypt the request

What is a common use for cookies in API requests?

• To authenticate or authorize users

• To store server data

• To define the API endpoint

• To format the response

What tool is introduced for manual API testing in the course?

• Selenium

• JMeter

• Swagger

• Postman

What is the significance of the content type in API headers?

• It specifies the server location

• It defines the format of the request data

• It is used for user authentication

• It determines the API endpoint

What is the primary focus of the next lecture after this video?

• Advanced API security

• Theoretical concepts of REST APIs

• Practical API testing using Postman

• Database integration with APIs
