不能用PowerMockito部分模拟静态方法

Question

public class Util {
    // Some code
    public static void toBeUnitTested(CustomObject cb, CustomObject1 cb1, List<CustomObject2> rows, boolean delete) {
        // some code

       toBeMockedFunction(cb, "test", "test");
    }

    public static CustomObject toBeMockedFunction(CustomObject cb, String str1) {
        // some code
    }

}

@RunWith(PowerMockRunner.class)
 @PrepareForTest({ Util.class})
 public class UtilTest {
    @Test
    public void Test1() {
        PowerMockito.spy(Util.class);            

 //mock toBeMocked function and make it do nothing 
 PowerMockito.when(PowerMockito.spy(Util.toBeMockedFunction((CustomObject)Mockito.anyObject(), Mockito.anyString()))).thenReturn(null);

        Util.toBeUnitTested(cb, "test", "test");
     }
  }

  PowerMockito.mockStatic(Util.class);  
  PowerMockito.when(Util.toBeUnitTested((CustomObject)Mockito.anyObject(),Mockito.anyString())).thenCallRealMethod();
    Util.toBeUnitTested(cb, "test", "test");

Answer 1

这是如何做到这一点的一个例子：

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Util.class})
public class UtilTest {
   @Test
   public void Test1() {

      PowerMockito.spy(Util.class);
      PowerMockito.doReturn(null).when(Util.class, "toBeMockedFunction", Mockito.any(CustomObject.class), Mockito.anyString(), Mockito.anyString());

      List<CustomObject2> customObject2List = new ArrayList<>();
      customObject2List.add(new CustomObject2());

      Util.toBeUnitTested(new CustomObject(), new CustomObject1(), customObject2List, true);
   }
}

请注意，您的OP的代码不编译。方法TobeMockedFunction(CustomObject cb,String str1)只接收2个参数，您使用3调用:TobeMockedFunction(cb,“Test”,“Test”）；。正如您所看到的，我已经将最后一个添加到方法签名中。

希望能有所帮助
