Get name of currently executing test in JUnit 4

JUnit 4.7 added this feature it seems using TestName-Rule. Looks like this will get you the method name:

import org.junit.Rule;

public class NameRuleTest {
    @Rule public TestName name = new TestName();

    @Test public void testA() {
        assertEquals("testA", name.getMethodName());
    }

    @Test public void testB() {
        assertEquals("testB", name.getMethodName());
    }
}

JUnit 4.9.x and higher

Since JUnit 4.9, the TestWatchman class has been deprecated in favour of the TestWatcher class, which has invocation:

@Rule
public TestRule watcher = new TestWatcher() {
   protected void starting(Description description) {
      System.out.println("Starting test: " + description.getMethodName());
   }
};

Note: The containing class must be declared public.

JUnit 4.7.x - 4.8.x

The following approach will print method names for all tests in a class:

@Rule
public MethodRule watchman = new TestWatchman() {
   public void starting(FrameworkMethod method) {
      System.out.println("Starting test: " + method.getName());
   }
};

JUnit 5 and higher

In JUnit 5 you can inject TestInfo which simplifies test metadata injection to test methods. For example:

@Test
@DisplayName("This is my test")
@Tag("It is my tag")
void test1(TestInfo testInfo) {
    assertEquals("This is my test", testInfo.getDisplayName());
    assertTrue(testInfo.getTags().contains("It is my tag"));
}

See more: JUnit 5 User guide, TestInfo javadoc.

Try this instead:

public class MyTest {
        @Rule
        public TestName testName = new TestName();

        @Rule
        public TestWatcher testWatcher = new TestWatcher() {
            @Override
            protected void starting(final Description description) {
                String methodName = description.getMethodName();
                String className = description.getClassName();
                className = className.substring(className.lastIndexOf('.') + 1);
                System.err.println("Starting JUnit-test: " + className + " " + methodName);
            }
        };

        @Test
        public void testA() {
                assertEquals("testA", testName.getMethodName());
        }

        @Test
        public void testB() {
                assertEquals("testB", testName.getMethodName());
        }
}

The output looks like this:

Starting JUnit-test: MyTest testA
Starting JUnit-test: MyTest testB

NOTE: This DOES NOT work if your test is a subclass of TestCase! The test runs but the @Rule code just never runs.
