How to obtain test case name in JUnit 4 at runtime?

Question

I want to do some logging while executing my JUnit test. In JUnit 3.x it was always easy to obtain the name of the currently running test case, no matter how the test case was instantiated:

public void testFoo() throws Exception() {
  String testName = this.getName();
  // [...] do some stuff
}

In JUnit 4 things seem to be not so easy. Does anyone know a solution to this? Is there any option to reflect into the current Runner instance?

Answer 1

What's wrong with:

@Test
public void foo() throws Exception() {
   String testName = this.getName();
   // [...] do some stuff
}

?

OK. I've found another approach somewhere on the Internet:

    @RunWith(Interceptors.class) 
    public class NameTest { 
            @Interceptor public TestName name = new TestName(); 

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

In JUnit 4.7, you can also get the name of the currently executed thest method. May be nice when logging.

Taken from JUnit 4.7 Release Notes (read them here at github) :

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());
 }
}
