list all methods name that is called by a method

public void testAdd() {

    /* Maths is the class in the source code containing add method() that i am trying to test here */
    Maths math = new Maths();

    String name = new Object(){}.getClass().getEnclosingMethod().getName();
    System.out.println(name);
    assertEquals(6.0, math.add(6.0, 0.0), DELTA);
    assertEquals(0.0, math.add(0.0, 0.0), DELTA);
    assertEquals(2.0, math.add(-5.0, 7.0), DELTA);
    assertEquals(-11.0, math.add(-5.0, -6.0), DELTA);
}

This is just a sample code.

I want to model Junit test cases to the source code method.

Like here if the given method is testAdd then i want to get all the methods names that this "testAdd" method is calling. Mainly i am interested to get math.add method details that is defined in source code.

Please let me know for any clarification.
