mock帶參數的構造函數

@RunWith(PowerMockRunner.class)
@PrepareForTest(Helper.class)//1.添加要初始化的類,就是構造函數所在的類
public class HelperTest {
  @Mock
  private Something mockSomething;
      
  @InjectMocks
  private Helper helper;
      
  @Test
  public void doSomething() throws Exception {
      String argument = "arg";
          
      PowerMockito.whenNew(Something.class).withArguments(argument).thenReturn(mockSomething);//2.添加要構造的函數的類,參數和返回值
          
      // 3.調用需要測試方法
      helper.doSomething(argument);
          
      // 進行驗證
      verify(mockSomething).doIt();
  }
}

public class Helper ｛
  public void doSomething(String arg) {
      Something something = new Something(arg);
      something.doit();
  }
}
