Spring Framework Master Class - Java Spring the Modern Way - Step 1-What is JUnit and Unit Testing?

The video introduces unit testing, explaining its purpose in ensuring application functionality. It contrasts unit testing with screen testing, highlighting the focus on specific methods or classes. The JUnit framework is discussed as a tool for automating unit tests, allowing for repeated testing and output verification. The video emphasizes the advantages of automated tests, such as continuous integration and notifications for test failures, ensuring code reliability.

What is the primary goal of unit testing?

• To replace manual testing entirely

• To test the user interface of an application

• To ensure individual methods or classes function as expected

• To test the entire application after deployment

How does unit testing differ from screen testing?

• Screen testing focuses on individual methods, while unit testing tests the whole application

• Unit testing is done after deployment, while screen testing is not

• Screen testing is automated, while unit testing is manual

• Unit testing focuses on individual methods or classes, while screen testing tests large chunks of functionality

What role does JUnit play in unit testing?

• It provides a user interface for testing

• It is a tool for manual testing

• It helps in calling specific methods and verifying their outputs

• It is used for testing the entire application

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

• They can be run continuously to catch errors early

• They require no initial setup

• They eliminate the need for any manual testing

• They are only run once before deployment

In the context of unit testing, what does continuous integration allow?

• Testing only the user interface

• Manual intervention for each test run

• Frequent and automatic running of tests whenever code changes

• Running tests only once a day
