這裏是我的間諜聲明的Mockito間諜調用窺探類的實際方法，而不是返回硬編碼的模擬
OAuthService oAuthServiceMock = Mockito.mock(OAuthService.class);
Mockito.doReturn(oAuthServiceMock).when(inviteServiceSpy.buildOAuthService(RESOURCE_URL, CONSUMER_KEY, CONSUMER_SECRET));
下面是實際的類
public OAuthService buildOAuthService(String RESOURCE_URL, String CONSUMER_KEY, String CONSUMER_SECRET) {
return new ServiceBuilder()
.provider(new DummyOAuth1ApiProvider(RESOURCE_URL))
.apiKey(CONSUMER_KEY)
.apiSecret(CONSUMER_SECRET)
.signatureType(SignatureType.Header).debug().build();
}
這裏的方法是我測試的一個片段案例和實際偵察類的實例（其中包含上述方法） 設置：
//This is in Setup/@Before method
myServiceSpy = Mockito.spy(new myServiceImpl());
測試用例：
@Test
public void testGetmyInviteData() throws Exception {
assertNotNull(myServiceSpy.getmyInviteData(signup_token,CONSUMER_KEY,CONSUMER_SECRET,RESOURCE_URL, RESOURCE_URL));
}
的問題是不是間諜那久違的嘲笑對象，實際方法看起來被稱爲拋出一個空指針異常。這是我運行這個測試時得到的異常。任何關於我可能做錯的想法以及如何使這一點變得更好，並避免得到實際的方法？
