Learn Java Unit Testing with JUnit 5 in 20 Steps - Step 08 - Setting up database connections - @BeforeAll, @AfterAll

The video tutorial explains the use of JUnit annotations to manage test setup and teardown processes efficiently. It covers the use of @BeforeEach and @AfterEach for individual test setups and @BeforeAll and @AfterAll for operations common to all tests, such as database connections. The importance of using static methods with @BeforeAll is highlighted, and the tutorial demonstrates how these annotations can optimize test execution by reducing redundant operations.

How does the 'after all' annotation contribute to resource management in tests?

What operations should be avoided in each test to improve efficiency?
