注释类型 Category

@Retention(RUNTIME)
@Inherited
public @interface Category

Marks a test class or test method as belonging to one or more categories of tests. The value is an array of arbitrary classes. This annotation is only interpreted by the Categories runner (at present). For example:

 public interface FastTests {}
 public interface SlowTests {}

 public static class A {
 @Test
 public void a() {
 fail();
 }

 @Category(SlowTests.class)
 @Test
 public void b() {
 }
 }

 @Category({SlowTests.class, FastTests.class})
 public static class B {
 @Test
 public void c() {

 }
 }
 

For more usage, see code example on Categories.
