请给出以下代码的junit白盒测试代码package service; import dao.TypeDao; import model.Type; import java.sql.SQLException; import java.util.List; public class TypeService { TypeDao tDao=new TypeDao(); public List<Type> GetAllType() { List<Type> list=null; try { list=tDao.GetAllType(); } catch (SQLException e) { e.printStackTrace(); } return list; } public Type selectTypeNameByID(int typeid) { Type type=null; try { type=tDao.selectTypeNameByID(typeid); } catch (SQLException e) { e.printStackTrace(); } return type; } public Type select(int id) { Type t=null; try { t = tDao.select(id); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } return t; } public void insert(Type t) { try { tDao.insert(t); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public void update(Type t) { try { tDao.update(t); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public boolean delete(int id) { try { tDao.delete(id); return true; } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); return false; } } }

以下是给出的Junit测试代码：

package service;

public class TypeServiceTest {

    @Mock
    private TypeDao typeDao;

    @InjectMocks
    private TypeService typeService;

    @Before
    public void setUp() throws Exception {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testGetAllType() throws SQLException {
        List<Type> expectedTypes = new ArrayList<Type>();
        Type type1 = new Type();
        type1.setId(1);
        type1.setName("Type 1");
        Type type2 = new Type();
        type2.setId(2);
        type2.setName("Type 2");
        expectedTypes.add(type1);
        expectedTypes.add(type2);

        // Mocking the DAO's behavior
        when(typeDao.GetAllType()).thenReturn(expectedTypes);

        List<Type> actualTypes = typeService.GetAllType();

        assertNotNull(actualTypes);
        assertEquals(expectedTypes.size(), actualTypes.size());
        assertTrue(actualTypes.containsAll(expectedTypes));
    }

    @Test
    public void testSelectTypeNameByID() throws SQLException {
        int typeId = 1;
        Type expectedType = new Type();
        expectedType.setId(typeId);
        expectedType.setName("Type 1");

        // Mocking the DAO's behavior
        when(typeDao.selectTypeNameByID(typeId)).thenReturn(expectedType);

        Type actualType = typeService.selectTypeNameByID(typeId);

        assertNotNull(actualType);
        assertEquals(expectedType, actualType);
    }

    @Test
    public void testSelect() throws SQLException {
        int id = 1;
        Type expectedType = new Type();
        expectedType.setId(id);
        expectedType.setName("Type 1");

        // Mocking the DAO's behavior
        when(typeDao.select(id)).thenReturn(expectedType);

        Type actualType = typeService.select(id);

        assertNotNull(actualType);
        assertEquals(expectedType, actualType);
    }

    @Test
    public void testInsert() throws SQLException {
        Type type = new Type();
        type.setId(1);
        type.setName("Type 1");

        typeService.insert(type);

        // Verifying that the DAO's insert method was called with the correct parameter
        verify(typeDao).insert(type);
    }

    @Test
    public void testUpdate() throws SQLException {
        Type type = new Type();
        type.setId(1);
        type.setName("Type 1");

        typeService.update(type);

        // Verifying that the DAO's update method was called with the correct parameter
        verify(typeDao).update(type);
    }

    @Test
    public void testDelete() throws SQLException {
        int id = 1;

        // Mocking the DAO's behavior
        when(typeDao.delete(id)).thenReturn(true);

        boolean result = typeService.delete(id);

        // Verifying that the DAO's delete method was called with the correct parameter
        verify(typeDao).delete(id);

        assertTrue(result);
    }
}

以上测试代码使用了Mockito框架来模拟TypeDao类的行为，在测试TypeService类的方法时，通过Mockito提供的when和verify方法来验证TypeService类的行为是否正确。测试代码中包含了对GetAllType、selectTypeNameByID、select、insert、update和delete方法的测试。
