Unable to Inject OSGI Services: jUnit !!

[kum_deep]

I am unable to get the reference of the OSGI Services when ran through Mockito. Every time I run the Test Class it gives me null wherever that service is invoked.

Any help is highly appreciated.

I am following this tutorial: Apache Sling - OSGi Mocks , but no luck.

Below is the code snippet (Test Class) that i run:

HashMap<Object, Object> _configServiceEndpoint = new HashMap<Object, Object>();

  HashMap<Object, Object> _configCommonConfig = new HashMap<Object, Object>();

  /** Mocking required sling request params */

  slingRequest = mock(SlingHttpServletRequest.class);

  /** Mocking required sling request params */

  slingResponse = mock(SlingHttpServletResponse.class);

  /** Setting Service End Point */

  _configServiceEndpoint.put("sendEmailURL",

  "https://MLIGATEWAY.MAXLIFEINSURANCE.COM/mli/prod/soa/MLI_E-mail_rest");

  _configServiceEndpoint.put("sendSmsURL", "https://gatewayuat.maxlifeinsurance.com/apimgm/sb/soa/sms/v2/real");

  _configServiceEndpoint.put("otpGenerationURL",

  "https://gatewayuat.maxlifeinsurance.com/apimgm/sb/soa/otp/generate?client_id=763b645e-4034-4152-9631...");

  _configServiceEndpoint.put("otpValidationURL",

  "https://gatewayuat.maxlifeinsurance.com/apimgm/sb/soa/otp/validate?client_id=763b645e-4034-4152-9631...");

  serviceEndPointConfigImpl = context.registerInjectActivateService(new ServiceEndPointImpl(),

  _configServiceEndpoint);

  /** Mocking up the timeout config needed for service Agent class */

  _configCommonConfig.put("serviceTimeOut", "25000");

  //commonConfigImpl = context.registerInjectActivateService(new CommonConfigImpl(), _configCommonConfig);

  GenerateOTP generateOTP = new GenerateOTP();

  SendOtpSms sendOtpSms = new SendOtpSms();

  SendOtpEmail sendOtpEmail = new SendOtpEmail();

  //ServiceAgent serviceAgent = new ServiceAgent();

  CommonConfigImpl commonConfig = new CommonConfigImpl();

  commonConfig = mock(CommonConfigImpl.class);

  serviceAgent = mock(ServiceAgent.class);

  BundleContext bundleContext = MockOsgi.newBundleContext();

  MockOsgi.activate(commonConfig, bundleContext, _configCommonConfig);

  //MockOsgi.injectServices(cmConfig, bundleContext);

  MockOsgi.activate(serviceAgent, bundleContext);

  MockOsgi.injectServices(commonConfig, bundleContext);

  MockOsgi.activate(generateOTP, bundleContext);

  MockOsgi.injectServices(serviceAgent, bundleContext);

  MockOsgi.activate(sendOtpSms, bundleContext);

  MockOsgi.injectServices(serviceAgent, bundleContext);

  MockOsgi.activate(sendOtpEmail, bundleContext);

  MockOsgi.injectServices(serviceAgent, bundleContext);

@Test

    public void testMethods() throws Exception{

  this.doGet(slingRequest, slingResponse);

    }

The class where "doGet" is implemented, has two service References which internally reference another Service.

It gives me the following error:

org.apache.sling.testing.mock.osgi.ReferenceViolationException: Unable to inject mandatory reference 'commonConfig' for class com.mli.neo.global.http.ServiceAgent : no matching services were found.

Request a concrete solution to achieve this. Any help is highly appreciated.

Watch this GEMS session on testing - it will point you in the right direction: From Unit Testing to Integration Test of an AEM Application

[Diego_Fontan · Accepted solution]

normally this error happens because you have missed mocking some internal operation as well, for example, if your method internally has something like this session.getRootNode().addNode(...); in this case, your test must also mock  getRootNode().addNode(...) otherwise your method will fail

Could you share the Code snippet of your class?

Thanks, Diego
I tried Power Mock and it worked.

I got the same error and easily fixed to add all the dependency services (i.e. @reference ) to context via context.registerService method. For example your service has a reference to QueryBuilder like @ @Referenceprivate QueryBuilder builder; then you need to do 2 things in your test class. first, create a mock @Mock QueryBuilder builder; 2nd - context.registerService(QueryBuilder.class, builder); in your setup method the definitely problem will be solved.
