PowerMockito模擬靜態無法正常作業

2022-06-22 16:24:39 企業開發

我有一個類需要測驗:

public class TestClazz {

    public void abc() {
        List<String> sa = Collections.singletonList("sa");
        Stream<PropertySource<?>> stream = StreamSupport.stream(Mockito.mock(Spliterator.class), false);
        ICampaignHandler campaignHandler = CampaignHandlerFactory.getCampaignHandler(ProcessorTypeEnum.RETRY_CAMPAIGN);

        System.out.println("============INSIDE ABC===========");
        System.out.println(sa);
        System.out.println(stream);
        System.out.println(campaignHandler);

        //Other logic code
    }

}

和一個測驗類:

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Collections.class, StreamSupport.class, CampaignHandlerFactory.class})
public class DefaultSystemAppConfigServiceTest {

    @Test
    public void testing() {
        PowerMockito.mockStatic(StreamSupport.class);
        PowerMockito.mockStatic(Collections.class);
        PowerMockito.mockStatic(CampaignHandlerFactory.class);

        //Stubbing
        Mockito.when(StreamSupport.stream(Mockito.any(Spliterator.class), Mockito.anyBoolean()))
                .thenReturn(Mockito.mock(Stream.class));
        Mockito.when(Collections.singletonList(Mockito.any()))
                .thenReturn(Mockito.mock(List.class));
        Mockito.when(CampaignHandlerFactory.getCampaignHandler(Mockito.any()))
                .thenReturn(Mockito.mock(ICampaignHandler.class));

        //Here invoked method under test
        new TestClazz().abc();

        Stream<PropertySource<?>> stream = StreamSupport.stream(Mockito.mock(Spliterator.class), false);
        List<String> sa = Collections.singletonList("sa");
        ICampaignHandler campaignHandler = CampaignHandlerFactory.getCampaignHandler(ProcessorTypeEnum.RETRY_CAMPAIGN);

        System.out.println();
        System.out.println("============OUTSIDE ABC===========");
        System.out.println(sa);
        System.out.println(stream);
        System.out.println(campaignHandler);
    }
}

我必須模擬靜態呼叫,以便它按我的期望回傳

我按照以下步驟操作:

  1. @RunWith(PowerMockRunner.class)
  2. @PrepareForTest({ Collections.class, StreamSupport.class, CampaignHandlerFactory.class})
  3. PowerMockito.mockStatic(clazz)
  4. Mockito.when(方法呼叫).thenReturn(我的模擬)
  5. 呼叫方法需要測驗

結果:

============INSIDE ABC===========
[sa]
java.util.stream.ReferencePipeline$Head@dffa30b
Mock for ICampaignHandler, hashCode: 81269359

============OUTSIDE ABC===========
Mock for List, hashCode: 628164202
Mock for Stream, hashCode: 1962826086
Mock for ICampaignHandler, hashCode: 81269359

Process finished with exit code 0

如果靜態呼叫在 abc() 內部,你們可以看到 2/3 我的存根設定不起作用,如果我在 abc() 外部復制靜態呼叫(直接復制到 testing()),它就可以作業。只有 1/3 的存根作業(內部和外部):

CampaignHandlerFactory.getCampaignHandler(param)   //this return as my expectiation

提示:CampaignHandlerFactory 是我的實作;Collections, StreamSupport 是內置類。這是春季啟動應用程式

問題:那么這里的問題是什么?如果靜態呼叫在 abc() 中,為什么我的存根不起作用,但只有 CampaignHandlerFactory 有效?

有版本沖突嗎?

uj5u.com熱心網友回復:

java.util.Collections并且java.util.stream.StreamSupport是系統類(作為 JRE 一部分的語言和實用程式庫)。系統類的呼叫者應該定義在@PrepareForTest({ClassThatCallsTheSystemClass.class}).
請參閱檔案

不過,模擬系統類的方式與平時有所不同。通常你會準備一個包含你喜歡模擬的靜態方法(我們稱之為 X)的類,但是因為 PowerMock 不可能準備一個系統類來進行測驗,所以必須采取另一種方法。因此,您無需準備 X,而是準備呼叫 X 中的靜態方法的類!

所以你需要添加TestClazz.class@PrepareForTest.
正確定義:

@PrepareForTest({ CampaignHandlerFactory.class, TestClazz.class})

執行測驗結果:

============INSIDE ABC===========
Mock for List, hashCode: 1800605369
Mock for Stream, hashCode: 847606512
Mock for ICampaignHandler, hashCode: 1736458419

============OUTSIDE ABC===========
Mock for List, hashCode: 1800605369
Mock for Stream, hashCode: 847606512
Mock for ICampaignHandler, hashCode: 1736458419
