java - 添加在 @PrepareForTest 中编写 Junit 的类可以使 Sonar 覆盖率为零

Question

示例 Controller

public class SampleController {

    public void sampleMethod() {
    ClassAbc classAbc = new ClassAbc();
    classAbc.abcMethod();
    //doStuff
    }
}

Abc 类

public class ClassAbc {
    public void abcMethod() {
    //doStuff
    }
}

用于 SampleController 的 Junit

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@PrepareForTest({SampleController.class})
public class SampleControllerTest {

    @Autowired
    SampleController sampleController;

    public void setUp() {
        ClassAbc classAbc = PowerMockito.mock(ClassAbc.class);
        PowerMockito.whenNew(ClassAbc.class).withAnyArguments()                                                                                                           
                                          .thenReturn(classAbc);
        doNothing().when(classAbc).abcMethod();
    }

    @Test
    public void testsampleMethod() throws Exception {
        sampleController.sampleMethod();
    }
}

当我在@PrepareForTest中添加“SampleController.class”时，即:

@PrepareForTest({SampleController.class})

当我运行 Sonar 作业时，我收到以下违规信息。

14 more branches need to be covered by unit tests to reach the minimum threshold of 65.0% branch coverage.

这就是我对该类的覆盖率为零。

我想知道是否有必要将调用构造函数的类放入@PrepareForTest注释中，而不是正在构造的类中。

或者有人可以帮我找到解决 Sonar 违规问题的解决方案吗？提前致谢

如 PowerMockito wiki 中所述:

... right now there is NO WAY TO USE PowerMock with JaCoCo On-the-fly instrumentation. ... to get code coverage with JaCoCo - use offline Instrumentation ... You may find example of using PowerMock with JaCoCo Offline Instrumentation and Maven in our repository: jacoco-offline example.
