ATG的Junit和Mockito

Question

我已经创建了一个类，它扩展了CommerceItemManager并覆盖了createCommerceItem方法。现在，我想为这个类编写一个junit和Mockito测试。下面是测试类的基本逻辑：

public class CustomizeCommerceItemManagerTest {

    @Spy @InjectMocks CustomizeCommerceItemManager commerceItemManager;

    @Before
    public void setUp(){
        initMocks(this);
    }

    @Test
    public void shouldDoSomething(){
    }
}

但是，当我运行这个类时，它会抛出一个异常：

atg.nucleus.logging.ClassLoggingFactory.getFactory(ClassLoggingFactory.java:106) at atg.core.i18n.LayeredResourceBundle.(LayeredResourceBundle.java:153) at atg.commerce.order.CommerceItemManager.(CommerceItemManager.java:93) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) 原因: java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1564)：无法找到基本名称atg.nucleus.NucleusResources的捆绑包，java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1387) at java.util.ResourceBundle.getBundle(ResourceBundle.java:845) at atg.nucleus.GenericContext.(GenericContext.java:113) . 46

我发现CommerceItemManager内部有一个参数：

protected static ResourceBundle sResourceBundle = LayeredResourceBundle.getBundle("atg.commerce.order.OrderResources", LangLicense.getLicensedDefault());

我尝试过使用PorwerMock来模拟这个参数，但是没有帮助。

@RunWith(PowerMockRunner.class)
@PrepareForTest({LayeredResourceBundle.class})
public class CustomizeCommerceItemManagerTest {

    private CustomizeCommerceItemManager commerceItemManager;

    @Before
    public void setUp() {
        mockStatic(LayeredResourceBundle.class);
        when(LayeredResourceBundle.getBundle("atg.commerce.order.OrderResources", LangLicense.getLicensedDefault())).thenReturn(null);
        commerceItemManager = PowerMockito.spy(new CustomizeCommerceItemManager());
    }

    @Test
    public void shouldDoSomething() {
    }
} 

有人能给我提个建议吗？

我也有类似的问题，并且像你一样使用Powermock解决了这个问题，并创建了一个假ResourceBundle。

@Before
public void setUp() throws Exception {

     ResourceBundle resourceBundle = new ResourceBundle() {
        @Override
        protected Object handleGetObject(String key) {
            return "fake_translated_value";
        }

        @Override
        public Enumeration<String> getKeys() {
            return Collections.emptyEnumeration();
        }
    };

    mockStatic(LayeredResourceBundle.class);
    when(LayeredResourceBundle.getBundle(anyString(), any(java.util.Locale.class))).thenReturn(resourceBundle);
}

希望这能帮上忙。
