Test code:

@Test
 public void should_get_element_in_middle_position_in_linkList() {
     //获取单链表中的中位数
     Integer[] array = new Integer[]{1, 4, 6, 2, 3, 10, 9, 8, 11, 2, 19, 30};
     List<Integer> arrayList = Arrays.asList(array);
     SingleLink<Integer> singleLink = mock(SingleLink.class);
     when(singleLink.getNode(6)).thenReturn(10);
     when(singleLink.getNode(7)).thenReturn(9);
     Reduce reduce = new Reduce(arrayList);
     assertThat(reduce.getMedianInLinkList(singleLink)).isEqualTo(9.5);
     verify(singleLink, times(12)).addTailPointer(anyInt());
 }

How can singleLink has 12 times interaction with method addTailPointer? SingleLink is an interface which has to be implemented with a new class. so, even you pass mocked singleLink variable into getMedianInLinkList method, it will be replaced with new instance.

so, i think verify(singleLink, times(12)).addTailPointer(anyInt()); makes no sense.

Could someone just explain what the test want to do? It just make me confused when read the method name and chinese annotation. Thank you.

should_return_unrepeated_elements_from_evens
//去除数组中所有偶数组成的数组的重复数

@Test
public void should_return_unrepeated_elements_from_evens() {
    //去除数组中所有偶数组成的数组的重复数
    Integer[] array = new Integer[]{1, 2, 3, 4, 1, 5};
    List<Integer> arrayList = Arrays.asList(array);

    Integer[] result = new Integer[]{2, 4};
    List<Integer> resultList = Arrays.asList(result);

    Add add = new Add();
    assertThat(add.getUnrepeatedFromEvenIndex(arrayList)).isEqualTo(resultList);

}
