test cases in inner class and outer class with junit4

Question

I have 2-3 inner classes which have some test cases and those are running well(being tested). I also have some test cases in outer class but these test cases are not running. I have the following structure:

@org.junit.runner.RunWith(Enclosed.class)
public class Outer { 
    @Test
    public void test1() {
        assert("Outer" != null);
    }

    public static class Inner1 {
        @Test
        public void test2() {
            assert("Inner1" != null);
        }
    }

    public static class Inner2 {
        @Test
        public void test3() {
            assert("Inner2" != null);
        }
    }
}

When I run this code, only test2 and test3 are being tested. test1 is not running. I want to run all test cases. So is this possible with Junit4 or is there any other way to achieve this?

Thanks in advance.

Answer 1

A work-around would be to put all tests from Outer into a new inner class:

@org.junit.runner.RunWith(Enclosed.class)
public class Outer {
    public static class Inner {
        @Test
        public void test1() {
            assert ("Outer" != null);
        }
    }

    public static class Inner1 {
        @Test
        public void test2() {
            assert ("Inner1" != null);
        }
    }

    public static class Inner2 {
        @Test
        public void test3() {
            assert ("Inner2" != null);
        }
    }
}
