I am using jacoco offline instumentation but dont see code coverage in the report for private function- getName(). When i run the jacoco reports, the coverage for getName() is 0%. Is there something wrong with the Junit or the configurations?

Below is the main class

public class CheckNameHandler implements RequestHandler<S3Event, Void> {
   @Override
   public Void handleRequest(S3Event s3Event, Context context) {
    String name = getName();
    return null;
  }
   private String getName(){
    return "test";
   }
}

Below is the test class

public class CheckNameHandlerTest {
 @Test
 public void handlerSuccessTest() {
  CheckNameHandler spyCheckNameHandler = PowerMockito.spy(new CheckNameHandler());
  PowerMockito.doReturn("test").when(spyCheckNameHandler, "getName");
  S3Event s3Event = .......;
  Context context = .......;
  spyCheckNameHandler.handleRequest(s3Event, context);
}

Below is the pom.xml

  • Does this answer your question? [JaCoCo + Mockito + Android tests: Zero coverage reported](https://stackoverflow.com/questions/46517471/jacoco-mockito-android-tests-zero-coverage-reported) – Godin Aug 08 '21 at 22:12
  • No it doesnot. Jacoco reports the code coverage for handleRequest as 100% but doesnot show any coverage for getName(). How do i get complete coverage for the class without writing test case for private method (getName()) – NKZ Aug 09 '21 at 00:09
  • Please read my answer in https://stackoverflow.com/a/46614216/244993 carefully - similarly to it IMO there is clearly something wrong with your expectations/understanding about core thing here - mocking: you're mocking `getName` - `PowerMockito.doReturn("test").when(spyCheckNameHandler, "getName");` so why do you expect non zero coverage for it? – Godin Aug 09 '21 at 09:13
