Stuck in Service IMPL Junit test class
1 Accepted Solution
Correct answer by
The null pointer exception could be caused by several reasons. One possible reason is that the `clientIntegrationDataAPIService` mock object is not properly initialized. You can try adding the `@RunWith(MockitoJUnitRunner.class)` annotation to the test class to initialize the mock objects.
@RunWith(MockitoJUnitRunner.class)
class ClientIntegrationDataAPIServiceImplTest {
// rest of the code
}
If this does not solve the issue, you can provide more information about the exception message and stack trace to help identify the root cause of the problem.
Hi @subnaik
Based on the code you provided, it seems that the clientIntegrationDataAPIServiceImpl object is not properly initialized in your JUnit test class, which is causing the NullPointerException when you call the requestCommunityCreation method.
To fix this issue, you need to properly initialize the clientIntegrationDataAPIServiceImpl object in your JUnit test class. One way to do this is to use a mocking framework like Mockito to create a mock object of the ClientIntegrationDataAPIServiceImpl class, and then inject this mock object into your test class using the @InjectMocks annotation.
import static com.github.tomakehurst.wiremock.client.WireMock.aResponse;
import static com.github.tomakehurst.wiremock.client.WireMock.post;
import static com.github.tomakehurst.wiremock.core.WireMockConfiguration.wireMockConfig;
import java.io.IOException;
import java.net.URISyntaxException;
import javax.jcr.RepositoryException;
import org.apache.sling.api.resource.LoginException;
import org.apache.sling.testing.mock.sling.ResourceResolverType;
import org.junit.Assert;
import org.junit.Rule;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnit;
import org.mockito.junit.MockitoRule;
import com.github.tomakehurst.wiremock.WireMockServer;
import ai.contentadmin.core.constants.Constants;
import ai.contentadmin.core.models.authorapi.ClientCommunity;
import io.wcm.testing.mock.aem.junit5.AemContext;
class ClientIntegrationDataAPIServiceImplTest {
private WireMockServer wireMockServer = new WireMockServer(wireMockConfig().dynamicPort());
@Rule
public final AemContext context = new AemContext(ResourceResolverType.JCR_MOCK);
@Rule
public MockitoRule mockitoRule = MockitoJUnit.rule();
@Mock
private ClientIntegrationDataAPIService clientIntegrationDataAPIService;
@InjectMocks
private ClientIntegrationDataAPIServiceImpl clientIntegrationDataAPIServiceImpl;
@Test
void requestCommunityCreation() throws IOException, URISyntaxException, LoginException, RepositoryException {
wireMockServer.stubFor(post("/search".concat(String.format(Constants.COMMUNITIES)))
.willReturn(aResponse().withStatus(200).withHeader("Content-Type", "application/json")));
ClientCommunity clientCommunity = new ClientCommunity();
clientCommunity.setName("TestCommunity");
clientCommunity.setUserId("userid");
clientCommunity.setType("client");
clientCommunity.setPrivate(true);
String expected = Constants.STATUS_OK;
Mockito.when(clientIntegrationDataAPIService.requestCommunityCreation(clientCommunity)).thenReturn(expected);
String actual = clientIntegrationDataAPIServiceImpl.requestCommunityCreation(clientCommunity);
Assert.assertEquals("Response should match", expected, actual);
wireMockServer.stop();
}
}
In this modified test class, we have added the @Mock annotation to create a mock object of the ClientIntegrationDataAPIService interface, and the @InjectMocks annotation to inject this mock object into the clientIntegrationDataAPIServiceImpl object. We have also used the Mockito.when method to mock the requestCommunityCreation method of the ClientIntegrationDataAPIService interface, and return the expected result when this method is called.
