Code coverage with JaCoCo appears not to show lines as partially covered?

Hello,

I'm facing same issue but I'm still searching…

It would be great to have any explanation...! :D

Regards,

Sylvain

please create a ticket here https://youtrack.jetbrains.com/issues/IDEA and provide a sample project so we can take a look at it from our side, thank you!

Hello,

I've made a simple test and I reproduce my weird case with JACOCO :

I just don't know why this is happening because we can see in the screen shot that the tested service ThrowService is fully covered, but not the actuel JUnit test method throwServiceTest…

- Do I get rid of the JUnit package when launching the Code Coverage with Jacoco ?

- Is something that I'm doing wrong ?

I'm using :

JAVA :  jdk-11.0.20 

SPRING : 

org.springframework.boot:spring-boot-starter-test:2.7.16

org.junit.jupiter:junit-jupiter-engine:5.8.2

org.junit.platform:junit-platform-launcher:1.8.2

org.junit.vintage:junit-vintage-engine5.8.2

…and Intellij :

IntelliJ IDEA 2023.2.4 (Ultimate Edition)

Here is the code :

@Slf4j
@ExtendWith(MockitoExtension.class)
class ThrowServiceTest {

    @InjectMocks
    private ThrowService throwService;

    @Test
    void throwServiceTest() {

       Assertions.assertThatExceptionOfType(UnsupportedOperationException.class)
             .isThrownBy(() ->
                   throwService.throwException()
             )
             .withNoCause();
    }
}

And the service :

@Slf4j
@Service
public class ThrowService {

    public void throwException() {
       throw new UnsupportedOperationException("Some message...");
    }
}

EDIT : Ok, I'm sorry for that ! :D

Sylvainsa Hello! Please try the latest IDEA version 2023.3.

The service itself looks actually fully covered, while you shared with us the coverage of the test class. The numbers show 6/7 lines covered, so we see one line as uncovered. 

Note: you can disable coverage in test folders with ‘Enable coverage in test folders’ option: https://www.jetbrains.com/help/idea/running-test-with-coverage.html#coverage-run-configurations

For further investigation, could you please generate an HTML report and share a screenshot of it https://www.jetbrains.com/help/idea/generating-code-coverage-report.html ?
