Unable to Inject OSGI Services: jUnit !!

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-4034-4152-9631-840ed5719ad8&client_secret=X8hT0tW1vS7gD2qE7gK1lD1kE8iF1rF7vG5bQ1gI0jG4xX3jI6");

  _configServiceEndpoint.put("otpValidationURL",

  "https://gatewayuat.maxlifeinsurance.com/apimgm/sb/soa/otp/validate?client_id=763b645e-4034-4152-9631-840ed5719ad8&client_secret=X8hT0tW1vS7gD2qE7gK1lD1kE8iF1rF7vG5bQ1gI0jG4xX3jI6");

  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.
