Understanding JUnit 5 @AfterEach Annotation with Practical Examples

This post has been merged into a single, updated guide covering both @BeforeEach and @AfterEach together, with a per-method lifecycle diagram and a JUnit 6 compatibility note: JUnit @BeforeEach and @AfterEach: The Complete Test Lifecycle Guide.

Everything that was here — the database connection, temporary file, and system property teardown examples, the inheritance ordering rules, and the exception-handling behavior — is preserved in the merged post, alongside the corresponding @BeforeEach content and new material.
