Using the `TestInstancePostProcessor` Extension
Explore how to implement the TestInstancePostProcessor extension in JUnit 5. Learn to create custom extensions that run after test instance creation, enabling automatic injection of dependencies such as loggers or mocks. Understand how to apply this with the @ExtendWith annotation to enhance your unit testing.
