如何模拟应用程序上下文

Question

我们如何模拟应用程序上下文？我有一个主持人打算为了编写测试。它收到的参数为view和Context。如何为上下文创建模拟？

public TutorProfilePresenter(TutorProfileScreenView view, Context context){
     this.view = view;
     this.context = context
}
            
public void setPrice(float price,int selectedTopics){
      int topicsPrice = 0;
      if(selectedTopics>2)
      {
        topicsPrice = (int) ((price/5.0)*(selectedTopics-2));
      }
                    
                    
      view.setBasePrice(price,topicsPrice,selectedTopics,
                        price+topicsPrice);
}

Answer 1

作为基础，我将使用Mockito注释(我假设您也想模拟视图(：

public class TutorProfilePresenter{
   @InjectMocks
   private TutorProfilePresenter presenter;
   @Mock
   private TutorProfileScreenView viewMock;
   @Mock
   private Context contextMock;
   @Before
   public void init(){
       MockitoAnnotations.initMocks(this);
   }
   @Test
   public void test() throws Exception{
      // configure mocks
      when(contextMock.someMethod()).thenReturn(someValue);
      // call method on presenter
      // verify
      verify(viewMock).setBasePrice(someNumber...)
   }
}

这将注入准备将模拟配置为正在测试的课程中。
