Mockito - calling an internal method

Question

I have a class called Availability.javaand two methods.

 public Long getStockLevelStage() {
     //some logic
      getStockLevelLimit();
    }

    public Long getStockLevelLimit() {
      String primaryOnlineArea = classificationFeatureHelper.getFirstFeatureName(productModel, FEATURE_CODE_PRODUCT_ONLINE_AREA_PRIMARY, language);
................
      return new Long();
    }

I am writing unit test class AvailabilityTest.java.

@RunWith(MockitoJUnitRunner.class)
public class AvailabilityTest {
  @InjectMocks
  private Availability availability = new Availability();

  @Test
  public void testGetStockLevelStage() {
    availability.getStockLevelStage();
  }
}

When I call a method availability.getStockLevelStage(), it calls a method getStockLevelLimit(). Is it possible to make fun of a call to an internal method?

In this case, I do not want to be getStockLevelLimit()executed when executed getStockLevelStage().

Please, help.

Answer 1

if getStockLevelLimit()it should not be executed during the test, it means that you want to mock the tested class.
Doing this reduces the relevance and authenticity of the behavior tested.

, .
, getStockLevelLimit(), , - .
, getStockLevelLimit(), Availability.

:

@RunWith(MockitoJUnitRunner.class)
public class AvailabilityTest {
    @InjectMocks
    @Spy
    private Availability availability = new Availability();

    @Test
    public void testGetStockLevelStage() {
       Mockito.doReturn(expectedLong).when(availability).getStockLevelLimit();
       availability.getStockLevelStage();
    }
}
