java - 如何使用@Resource 对 boolean 字段进行单元测试

Question

我想测试一些类。那个类有带@Resource 的 boolean 字段。我不能模拟这个字段。因此它给出测试失败并出现一些错误。如果有人能告诉我如何测试这个类。

这是我的java类

public class RefreshHandlerImpl implements RefreshHandler
{
  @Resource(name = "readOnlyMode")
  private Boolean readOnlyMode;


  @Override
  public ContactBedRefreshResult refreshContactsAndBeds(final Unit unit, final boolean hasWritableTransaction)
throws RequiresWritableTransactionException
  {

    if (!isReadOnlyMode())
    {
      //some code here
    }

  }



  private boolean isReadOnlyMode()
  {
    return readOnlyMode;
  }

}

我尝试模拟“readOnlyMode”字段。但它给出了错误。

org.mockito.exceptions.base.MockitoException: Cannot mock/spy class java.lang.Boolean Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types

这是我的testng测试类

public class RefreshHandlerImplTest
{

 @Mock(name = "readOnlyMode")
 private Boolean readOnlyMode;

 @InjectMocks
 private RefreshHandlerImpl refreshHandlerImpl;

 @BeforeMethod
 public void setUp() throws Exception {
   initMocks(this);
 }

 @Test
 public void testRefreshContactsAndBeds_ReturnsZeroContactsWhenCollaboratorsDoes()
  throws Exception
 {
   ContactBedRefreshResult result = refreshHandlerImpl.refreshContactsAndBeds(unit, true);
   assertThat(result.getContacts()).isEmpty();
 }
}

我可以使用反射，然后如何使用？我不能更改我的java类。只能更改测试类。

Answer 1

我使用 org.springframework.test.util.ReflectionTestUtils 解决了这个问题

我删除了@Mock(name = "readOnlyMode")
private Boolean readOnlyMode;并在我的 @BeforeMethod 方法中使用了ReflectionTestUtils.setField(refreshHandlerImpl,RefreshHandlerImpl.class,"readOnlyMode",true,Boolean.class);。这是我的测试课，

public class RefreshHandlerImplTest
{
 @InjectMocks
 private RefreshHandlerImpl refreshHandlerImpl;

 @BeforeMethod
 public void setUp() throws Exception {
  initMocks(this);
  ReflectionTestUtils.setField(refreshHandlerImpl,RefreshHandlerImpl.class,"readOnlyMode",true,Boolean.class);
 }

 @Test
 public void testRefreshContactsAndBeds_ReturnsZeroContactsWhenCollaboratorsDoes() throws Exception
 {
   ContactBedRefreshResult result = 
   refreshHandlerImpl.refreshContactsAndBeds(unit, true);
   assertThat(result.getContacts()).isEmpty();
 }
}
