UnfinishedStubbingException和PowerMockito

我想測試一個使用靜態方法的方法，這就是爲什麼我使用PowerMockito。我想嘲笑來自Http Client Fluent API的Request.Get。我安裝了一個簡單的測試，但我得到了一個UnfinishedStubbingException，我不明白爲什麼。UnfinishedStubbingException和PowerMockito

2.8.9的Mockito和Powermock 1.7.1

@RunWith(PowerMockRunner.class) 
@PrepareForTest(Request.class) 
public class MyApiServiceTest { 

    @Test 
    public void callTest() throws IOException, JSONException, URISyntaxException { 
     PowerMockito.mockStatic(Request.class); 
     Path path = Paths.get(getClass().getClassLoader().getResource("data.json").toURI()); 
     byte[] fileBytes = Files.readAllBytes(path); 
     Content content = new Content(fileBytes, ContentType.APPLICATION_JSON); 
     PowerMockito.doReturn(content).when(Request.Get(anyString()).execute().returnContent()); 
    } 

}

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here: 
-> at com.example.service.MyApiServiceTest.callTest(MyApiServiceTest.java:42) 

E.g. thenReturn() may be missing. 
Examples of correct stubbing: 
    when(mock.isOk()).thenReturn(true); 
    when(mock.isOk()).thenThrow(exception); 
    doThrow(exception).when(mock).someVoidMethod(); 
Hints: 
1. missing thenReturn() 
2. you are trying to stub a final method, which is not supported 
3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed

看來你正試圖在同一時間，以嘲笑的東西太多了。

嘗試獨立存根和returnContent()方法：

@Test 
    public void callTest() throws IOException, JSONException, URISyntaxException { 
     // Arrange 
     PowerMockito.mockStatic(Request.class); 
     Request requestStub = Mockito.mock(Request.class); 
     Response responseStub = Mockito.mock(Response.class); 
     Path path = Paths.get(getClass().getClassLoader().getResource("data.json").toURI()); 
     byte[] fileBytes = Files.readAllBytes(path); 
     Content content = new Content(fileBytes, ContentType.APPLICATION_JSON); 

     Mockito.doReturn(responseStub).when(requestStub).execute(); 
     Mockito.doReturn(content).when(responseStub).returnContent(); 
     PowerMockito.doReturn(requestStub).when(Request.class, Mockito.anyString(), "Get"); 

     // Act and assert 
    }

所以powermockito僅用於返回requestStub其餘全部可以用普通的Mockito來完成。

它也不起作用。我在PowerMockito.doReturn調用中遇到了同樣的異常。 – Sydney

你可以發佈堆棧跟蹤嗎？ –

嘗試使用有點不同的語法..請參閱更新 –
