running @Test one by one using reflection

I’m trying to run a package with many unit tests (one by one, not as a class) using reflection, So when I get all the @Test methods that needs to be run I try to do

Result result = new JUnitCore().run(Request.method(Class
                                .forName(packageAndClass),getTestName()));

But the class returned in packageAndClass has @Before, @BeforeClass methods (that also might be in its superclass)

So when running the code above I get all the tests running and fail(because some of their values are assigned in the @Before and @BeforeClass methods) But when running it from eclipse (select the test method name -> right click -> run as -> Junit test) They all pass (runing together or one by one) Is there an api of Request that will run the before methods?

I ran the following test with junit 4.9 :

public class RunOneTest {
    public static void main(final String[] args) {
        final Result result = new JUnitCore().run(Request.method(RunOneTest.class, "oneTest"));
        System.out.println("result " + result.wasSuccessful());
    }

    @Test
    public void oneTest() throws Exception {
        System.out.println("oneTest");
    }

    @Test
    public void anotherTest() throws Exception {
        System.out.println("anotherTest");
    }

    @Before
    public void before() {
        System.out.println("before");
    }

    @BeforeClass
    public static void beforeClass() {
        System.out.println("beforeClass");
    }

    @After
    public void after() {
        System.out.println("after");
    }

    @AfterClass
    public static void afterClass() {
        System.out.println("afterClass");
    }
}

and the output was :

beforeClass
before
oneTest
after
afterClass
result true

Are you really sure that the methods are not run ?

Why are you doing that? JUnit is supposed to run the tests for you!
