The following test will pass:25public void testAlternativeFlowWithWhitebox() throws Exception {26    WhenNewCases whenNewCases = new WhenNewCases();27    List<String> list = whenNewCases.testAlternativeFlowWithWhitebox();28    assertNotNull(list);29    assertEquals(1, list.size());30    assertEquals("hello", list.get(0));31}32The following is the testAlternativeFlowWithWhitebox() method in the WhenNewCases class:33public List<String> testAlternativeFlowWithWhitebox() throws Exception {34    PrivateConstructorWithFinalField privateConstructorWithFinalField = mock(Private
