jacoco显示行未覆盖，尽管在运行代码时执行了这些行

Question

我有以下代码行，它们被Jacoco指示为未“执行”。

但是，当我调试测试用例时，它会执行这些行。 以下是我编写的测试用例。

@PrepareForTest({MessagingAdapterFactory.class, MessagingConfigReaderFactory.class,UpdaterServiceExecutor.class,Files.class})
    @Test
    public void should_shutDown_the_scheduledExecutor_and_close_the_messagingAdapter() throws Exception {
        PowerMockito.mockStatic(Files.class);
        PowerMockito.when(Files.exists(any())).thenReturn(true);

        PowerMockito.mockStatic(MessagingAdapterFactory.class);
        PowerMockito.when(MessagingAdapterFactory.getMessagingAdapter("edgeNode")).thenReturn(messagingAdapterMock);
        PowerMockito.mockStatic(MessagingConfigReaderFactory.class);
        PowerMockito.when(MessagingConfigReaderFactory.getConfigurationReader()).thenReturn(readerMock);

        ScheduledExecutorService scheduledExecutorServiceMock = Mockito.mock(ScheduledExecutorService.class);

        PowerMockito.mockStatic(Executors.class);
        PowerMockito.when(Executors.newSingleThreadScheduledExecutor()).thenReturn(scheduledExecutorServiceMock);

        when(readerMock.getConfigParams()).thenReturn("somePath,somePath,somePath");
        when(decompressUtilMock.decompressZip(Matchers.anyString(),Matchers.anyString())).thenReturn(true);
        when(checkSumUtilMock.check(anyString(), anyString())).thenReturn(true);
        when(commandExecutorMock.executeCommand("somePath verify /pa somePathKubeUpdates/KubePlatformSetup.exe")).thenReturn(false);
        updaterServiceExecutor.execute();
        Thread.sleep(10000);
        updaterServiceExecutor.close();

        verify(scheduledExecutorServiceMock,timeout(10000).times(1)).shutdownNow();
        verify(messagingAdapterMock,timeout(10000).times(1)).close();
    }

    @PrepareForTest({MessagingAdapterFactory.class, MessagingConfigReaderFactory.class,UpdaterServiceExecutor.class,Files.class})
    @Test
    public void should_not_throw_ServiceSDKException_when_occurred_while_closing_the_messagingAdapter() throws Exception {
        PowerMockito.mockStatic(Files.class);
        PowerMockito.when(Files.exists(any())).thenReturn(true);

        PowerMockito.mockStatic(MessagingAdapterFactory.class);
        PowerMockito.when(MessagingAdapterFactory.getMessagingAdapter("edgeNode")).thenReturn(messagingAdapterMock);
        PowerMockito.mockStatic(MessagingConfigReaderFactory.class);
        PowerMockito.when(MessagingConfigReaderFactory.getConfigurationReader()).thenReturn(readerMock);

        ScheduledExecutorService scheduledExecutorServiceMock = Mockito.mock(ScheduledExecutorService.class);

        PowerMockito.mockStatic(Executors.class);
        PowerMockito.when(Executors.newSingleThreadScheduledExecutor()).thenReturn(scheduledExecutorServiceMock);

        when(readerMock.getConfigParams()).thenReturn("somePath,somePath,somePath");
        when(decompressUtilMock.decompressZip(Matchers.anyString(),Matchers.anyString())).thenReturn(true);
        when(checkSumUtilMock.check(anyString(), anyString())).thenReturn(true);
        when(commandExecutorMock.executeCommand("somePath verify /pa somePathKubeUpdates/KubePlatformSetup.exe")).thenReturn(false);
        doThrow(new ServiceSDKException()).when(messagingAdapterMock).close();

        updaterServiceExecutor.execute();
        Thread.sleep(10000);
        updaterServiceExecutor.close();

        verify(scheduledExecutorServiceMock,timeout(10000).times(1)).shutdownNow();
        verify(messagingAdapterMock,timeout(10000).times(1)).close();
    }

怎么了 为什么Jacoco显示未执行的行？ 请指教。

Answer 1

Jacoco和PowerMockito不能一起工作。

Jacoco检测字节码，收集覆盖率数据，然后基于该类的某些标识符将覆盖率信息与源代码相关联。

PowerMockito也会检测字节码，这会导致不同的类标识符，因此Jacoco计算的覆盖率不能与源代码相关联，因为标识符信息不匹配。

这是一个已知问题 。

杰拉尔德的答案就是原因。 仅当您将要测试的类放在@PrepareForTest中时，才会发生这种情况。 所以我从某些方法中删除了它，现在可以正常工作了。 拥有PowerMockito本身不会引起任何问题。 仅当您在@PrepareForTest中具有类名时，才会出现问题。 寻找仅使用静态方法类名称而不使用您要为其编写测试用例的类来管理它的方法。
