注释类型 BeforeClass
@Retention(RUNTIME) @Target(METHOD) public @interface BeforeClass
Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating apublic static void
no-arg method with@BeforeClass
causes it to be run once before any of the test methods in the class. The@BeforeClass
methods of superclasses will be run before those of the current class, unless they are shadowed in the current class.For example:
public class Example { @BeforeClass public static void onlyOnce() { ... } @Test public void one() { ... } @Test public void two() { ... } }
