Master Hibernate and JPA with Spring Boot in 100 Steps - Step 5: Important Annotations

The video tutorial introduces JUnit annotations, focusing on @Before, @After, @BeforeClass, and @AfterClass. It explains their roles in setting up and cleaning up tests, emphasizing that while test execution order isn't guaranteed, these annotations ensure specific methods run before or after tests. The tutorial highlights the importance of static methods for class-level annotations and discusses the practical benefits of JUnit in automation testing and learning new concepts.

What is the primary purpose of the @Before annotation in JUnit?

• To run code after each test

• To run code before each test

• To run code once before all tests

• To run code once after all tests

Which annotation is used for cleanup operations after each test in JUnit?

• @After

• @AfterClass

• @BeforeClass

• @Before

What is a key requirement for methods annotated with @BeforeClass in JUnit?

• They must be instance methods

• They must be static methods

• They must return a value

• They must throw an exception

What is the role of the @AfterClass annotation in JUnit?

• To run code after each test

• To run code before each test

• To run code once before all tests

• To run code once after all tests

Why is JUnit considered beneficial for automation testing?

• It allows for manual testing

• It can only be used once

• It is not widely adopted

• It helps find bugs quickly with repeated tests

How can JUnit assist in learning new programming concepts?

• By generating code automatically

• By offering debugging tools

• By providing a graphical user interface

• By writing tests to understand concepts better

What is a recommended practice for programmers regarding JUnit?

• To rely on it for code generation

• To avoid using it

• To master it for effective testing

• To use it only for large projects
