我努力用 來測試一門課，Junit我得到了一個NullPointerException.下面提供了我想測試的課程，@Componentpublic class EmailageConnector { private static final Logger LOG = LoggerFactory.getLogger( EmailageConnector.class ); private static final String BASIC_AUTHORIZATION = "Basic "; @Autowired private EmailageConfigHolder emailageConfigHolder; @Autowired private EntityServiceConnectable<EmailageResponseDto> connector; private String authorization; @PostConstruct void createAuthorization() { final String credentials = String.format( "%s%s%s", emailageConfigHolder.getAccountId(), ":", emailageConfigHolder.getApiKey() ); authorization = BASIC_AUTHORIZATION + encodeBase64String( credentials.getBytes() ); } // ======================================================================== public ServiceResponse<EmailageResponseDto> call( final RequestInformation requestInfo, final EmailageRequestDto request ) { if( LOG.isDebugEnabled() ) { LOG.debug( "call emailage [ requestInfo: {} - request: {}]", String.format( "%s", requestInfo ), String.format( "%s", request ) ); } return connector.call( request, createHeaders() ); } // ======================================================================== private HttpHeaders createHeaders() { final HttpHeaders headers = new HttpHeaders(); headers.add( AUTHORIZATION, authorization ); return headers; }}這是我的測試課，@RunWith( MockitoJUnitRunner.class )public class EmailageConnectorTest { @InjectMocks private EmailageConnector connector; @Spy private EmailageConfigHolder configHolder; @Mock EntityServiceConnectable<EmailageResponseDto> serviceConnector; @Captor private ArgumentCaptor<UriParam<?>> captor; }

對于 JUnit5 和 mockito，請參考這個答案：
How to use Mockito with JUnit5
我也更新了下面的示例。
Edit2：由于 TO 沒有說明正在使用哪個 JUnit 版本或 mockito 版本，如果仍然不起作用，我將嘗試編輯答案。
感謝您@helospark指出這一點。
使用 Runner 或 Rule 不適用于 JUnit5，因此可能應該使用 Mockito Version 2。
使用 Mockito Version 1 時，需要顯式調用 init 方法。
@BeforeEach
public void setUp() {
MockitoAnnotations.initMocks(this);
}
對于 Junit5 和最新的 Mockito 版本 (2.27)，測試類應該如下所示：
class InnerClass {
public void doSomething(String fileName) {
}
}
class SomeClass {
InnerClass innerClass;
public boolean doSomething(String fileName) {
innerClass.doSomething(fileName);
return true;
}
}
@ExtendWith(MockitoExtension.class)
class SomeClassTest {
@InjectMocks
SomeClass someClass;
@Mock
InnerClass innerClass;
@Test
public void test() {
someClass.doSomething("test");
Mockito.verify(innerClass, Mockito.times(1)).doSomething(Mockito.any());
}
}
