我有以下代码行，Jacoco 将其指示为未“执行”。

在此处输入图像描述

但是当我调试测试用例时，它确实执行了这些行。下面是我写的测试用例。

@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();
    }

这里有什么问题？为什么 Jacoco 显示为行尚未执行？请指教。

Jacoco 和 PowerMockito 不能一起工作。

Jacoco 检测字节码，收集覆盖数据，然后根据类的某些标识符将覆盖信息与源代码相关联。

PowerMockito 也检测字节码，这导致不同的类标识符，因此 Jacoco 计算的覆盖率无法与源代码相关联，因为标识符信息不匹配。

这是一个已知问题。

杰拉德的回答就是原因。仅当您将正在测试的类放入 @PrepareForTest 时才会发生这种情况。所以我从某些方法中删除了它，现在它工作正常。拥有 PowerMockito 本身不会导致任何问题。仅当您在 @PrepareForTest 中有类名时才会出现问题。寻找仅使用静态方法类的名称而不是您正在为其编写测试用例的类的名称来管理它的方法。
