我有一个带有布尔方法的ApiUtility Java类，希望为此编写JUNIT。
我在试着像下面这样。
我的Java类是蓝色的。

public static boolean isPublished(ResourceResolver resourceResolver, String path) {
   logger.info("Inside isPublished");
   Resource resource = resourceResolver.getResource(path);
   logger.info("Inside isPublished resource ===== "+ resource);
   Resource jcrResource = resource.getChild(Constants.JCR_CONTENT_NODE);
   if (jcrResource != null) {
      return jcrResource.getValueMap().get(Constants.CQ_LAST_REPLICATION_ACTION, "").equalsIgnoreCase(Constants.ACTIVATE);
   }
   return false;
   
}

我正试着写我的JUNIT类，如下所示。但不能。

import static org.mockito.Mockito.when;

public class AgenciesCommunityNodeAmangerServletTest {
    private static final Gson gson = new Gson();

    @Rule
    private final AemContext context = new AemContext(ResourceResolverType.JCR_MOCK);

    @Mock
    ContentFragmentService agenciesService;
    
    @Mock
    EntityRelationUpdateServiceImpl updateService;

    @InjectMocks
    private AgenciesCommunityNodeAmangerServlet agenciesCommunityNodeAmangerServlet = new AgenciesCommunityNodeAmangerServlet();

    private final String COMMUNITY_PATH = "/content/dam/content-admin/global/communities/agency/test";
    
    @BeforeEach
    void setUp() throws RepositoryException, URISyntaxException {
        MockitoAnnotations.initMocks(this);
        context.resourceResolver();
        String json = gson.toJson(TestUtils.getMockBRGCommunityModel("/content/dam/content-admin/global/communities/agency/test"));
        context.request().setContent(json.getBytes());
    }

    @Test
    void doPostUpdateRelationShouldReturn200() throws IOException, LoginException {
        when(updateService.updateEntityData(context.request(), COMMUNITY_PATH, Constants.COMMUNITIES)).thenReturn(TestUtils.getExpectedServletResponse(ServletResponse.ServletResponseType.RES_200));
        Map<String, Object> params = new HashMap<>();
        params.put(Constants.PATH, COMMUNITY_PATH);
        params.put(Constants.TYPE, Constants.VERIFY);
        context.request().setParameterMap(params);
        agenciesCommunityNodeAmangerServlet.doPost(context.request(), context.response());

        Assert.assertEquals("Response code should match", 200, context.response().getStatus());
    }
    
    @Test
    void doPostUpdateRelationShouldThrowExceptionReturn500() throws IOException, LoginException {
        when(updateService.updateEntityData(context.request(), COMMUNITY_PATH, Constants.COMMUNITIES)).thenReturn(TestUtils.getExpectedServletResponse(ServletResponse.ServletResponseType.RES_500));
        Map<String, Object> params = new HashMap<>();
        params.put(Constants.PATH, COMMUNITY_PATH);
        params.put(Constants.TYPE, Constants.VERIFY);
        context.request().setParameterMap(params);
        agenciesCommunityNodeAmangerServlet.doPost(context.request(), context.response());

        Assert.assertEquals("Response code should match", 500, context.response().getStatus());
    }

}

但我得到如下空指针异常。

我的servlet JAVA类如下所示

@Override
protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws IOException {
   
   String type = request.getParameter(Constants.TYPE) != null ? request.getParameter(Constants.TYPE) : "";
   logger.info("type outside IF Statement !type.isEmpty() ======= " + type);  
   
   //AgenciesCommunityModel agenciesCommunityModel = gson.fromJson(request.getReader(),AgenciesCommunityModel.class);//coming value here
   
   if (!type.isEmpty() && type.equals(Constants.VERIFY)) {
      logger.info("type INSIDE IF Statement !type.isEmpty() ======= " + type);
      boolean publishStatus = ApiUtility.isPublished(request.getResourceResolver(),request.getPathInfo());
      logger.info("publishStatus INSIDE agenciesCommunity ======= " + publishStatus);
      if (publishStatus == true) {
         ApiUtility.verifyContentFromMDS(updateRelationService, request, response, Constants.COMMUNITIES);
      }
   }

因为我从来没有在JUNIT上工作过，谁能帮帮我吗？
我正在写一个JUNIt测试类，但是没有成功。

请同时提供资源模拟，看起来资源解析器返回null。

您永远不会到达被测方法，因为您的模拟设置不正确。
问题出在：

when(ApiUtility.isPublished(resourceResolver, COMMUNITY_PATH)).thenReturn(true);

这是stub静态方法的错误方法。请参阅Mockito文档中的Mocking static methods了解正确的方法。
通常，Mockito会报告不正确的清除尝试，如：

org.mockito.exceptions.misusing.MissingMethodInvocationException: 
when() requires an argument which has to be 'a method call on a mock'.
For example:
    when(mock.getArticles()).thenReturn(articles);

Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
   Those methods *cannot* be stubbed/verified.
   Mocking methods declared on non-public parent classes is not supported.
2. inside when() you don't call method on mock but on some other object.

您不会收到此消息，因为您在前一步遇到了NPE异常-您调用isPublished的真实的实现，NPE从其中抛出。
NPE被抛出，因为您没有在resourceResolver上存根任何方法。
