Mockito - Wanted but not invoked: Actually, there were zero interactions with this mock

要測試的類:IndexController.java

代碼:

@Mock
private TemplateWrapper templateWrapper = spy(new TemplateWrapper());

@InjectMocks
private IndexController controller;

verify(templateWrapper).process();

報錯:

Wanted but not invoked:
templateWrapper.process();
-> at com.suning.ebuy.cms.web.controller.IndexControllerTest.testIndexSuccess(IndexControllerTest.java:199)
Actually, there were zero interactions with this mock.

錯誤原因:沒有把templateWrapper注入到IndexController.java類中.

解決方法:

1.把templateWrapper注入到IndexController.java類中

controller.setMyObj(templateWrapper); //it is good to have in @before method

2.或者創建templateWrapper的實例類,再執行verify(templateWrapper).process();

templateWrapper = new TemplateWrapper();

verify(templateWrapper).process();
