7. Apache JMeter is an open-source tool designed for performance testing and load testing web applications. It simulates multiple users sending requests to a server, measuring how well the server performs under load.

JUnit is mainly used for unit testing in Java applications. It is a widely-used testing framework that helps developers write and run tests to verify that individual parts of their code (called units, typically methods or classes) work correctly.

Yes, Postman is widely used for API testing. It is a popular tool that allows developers and testers to send HTTP requests to REST APIs and inspect the responses. With Postman, you can test various aspects of an API, such as:

• Request methods (GET, POST, PUT, DELETE, etc.)

• Headers and authentication

• Request bodies and parameters

• Response status codes and data

Postman provides an easy-to-use graphical interface, making it simple to create, test, and organize API requests into collections. You can also write test scripts in JavaScript to automate response validation and create test suites for continuous integration.

In full stack development, Postman is commonly used to test backend APIs (like those built with Spring Boot) before connecting them to the frontend. It helps ensure the API behaves correctly, handles errors properly, and returns the expected data.

So, Postman is not just used for testing but also for debugging, documenting, and sharing APIs, making it an essential tool in modern API development.
