The documentation of JUnit 4 does leave out some feature gems, including this:

@RunWith(Suite.class)
@SuiteClasses({ATest.class, BTest.class, CTest.class})
public class MyTests() {
   @BeforeClass public void setupDatabaseBeforeEverything() { ... }
   @AfterClass public void teardownDatabaseAfterEverything() { ... }
} 

This will run

setupDatabaseBeforeEverything
ATest
BTest
CTest
teardownDatabaseAfterEverything
