Master Hibernate and JPA with Spring Boot in 100 Steps - Step 1: What is JUnit and Unit Testing?

The video introduces unit testing, explaining its purpose in ensuring application functionality. It differentiates unit testing from screen testing, emphasizing testing specific methods or classes. The JUnit framework is introduced as a tool for automating unit tests, allowing for frequent and automated testing. The video highlights the advantages of automated unit testing, such as continuous integration, which ensures tests run whenever code changes occur.

What is the primary goal of unit testing?

• To ensure individual methods or classes function as expected

• To replace manual testing entirely

• To test the user interface of an application

• To test the entire application after deployment

How does unit testing differ from screen testing?

• Unit testing focuses on the entire application, while screen testing focuses on specific methods

• Unit testing is manual, while screen testing is automated

• Unit testing targets specific methods or classes, while screen testing targets the entire application

• Unit testing is done after deployment, while screen testing is done before

What role does JUnit play in unit testing?

• It provides a graphical interface for testing

• It helps in writing and running tests for specific methods

• It automates the deployment process

• It is used for testing the user interface

What is one of the key benefits of using automated unit tests with JUnit?

• They require no maintenance once written

• They are only useful for small projects

• They can be run continuously and notify developers of failures

• They eliminate the need for any manual testing

How does continuous integration benefit from automated unit testing?

• It facilitates frequent testing whenever code changes occur

• It ensures tests are run manually by developers

• It allows tests to be run only once before deployment

• It reduces the need for version control systems
