因为我是 Mockito 和 AEM 模型 java 的新手。我浏览了一些文档并为 AEM Model java 编写了我的第一个 Mockito 文件。在我的代码中，我没有看到任何错误，但是在运行时我没有成功并且无法 100% 完成代码覆盖率。任何人都可以纠正/帮助我修复我的代码[给定示例 java 和相应的 mockito 文件]

Java 文件：

import javax.inject.Inject;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.resource.LoginException;

@Model(adaptables = SlingHttpServletRequest.class)
public class AccordionModel {
    private final static Logger log = LoggerFactory.getLogger(AccordionModel.class);
    @SlingObject
    private SlingHttpServletRequest request;
    @Inject
    public ResourceResolverService resolverService;
    private Resource resource;
    public List < Accordion > accordionList = new ArrayList < Accordion > ();
    @PostConstruct
    protected void init() throws LoginException, JSONException {
        log.info("AccordionModel init method Start");
        resource = request.getResource();
        final ValueMap configurationOptionProperties = resource.getValueMap();
        log.debug("iconfigurationOptionProperties is " + configurationOptionProperties);
        String count = configurationOptionProperties.get("count", String.class);
        if (count != null) {
            for (int i = 1; i <= Integer.valueOf(count); i++) {
                Accordion accordion = new Accordion();
                String title = configurationOptionProperties.get("title" + i, String.class);
                String rte = configurationOptionProperties.get("rte" + i, String.class);
                accordion.setTitle(title);
                accordion.setRte(rte);
                accordionList.add(accordion);
            }
        }
        log.info("AccordionModel init method End");
    }
    public List < Accordion > getAccordionList() {
        return accordionList;
    }
}

模拟代码

    String count = "6";
    //max count, based on this count loop execute and get/set into the list  
    @Before
    public void setUp() throws Exception {
        when(request.getResource()).thenReturn(resource);
        when(resource.getValueMap()).thenReturn(valuemap);
    }
    @Test
    public void shouldReturnNullWhenPropertyIsNull() throws LoginException, JSONException {
        when(valuemap.get("count", String.class)).thenReturn(null);
        accordionModel.init();
        assertEquals(accordionModel.getAccordionList(), null);
    }
    @Test
    public void shouldReturnWhenPropertyNotNull() throws LoginException, JSONException {
        when(valuemap.get("count", String.class)).thenReturn("count");
        accordionModel.init();
        assertEquals(accordionModel.getAccordionList(), count);
    }
}

程序显示错误-->accordionModel.init();

java.lang.AssertionError: expected:<[]> but was:<null>

如果您返回null您的列表是空的。所以调整你的测试。考虑重命名方法名称。如果那不是您想要的，您将需要更改您的实现。

@Test
public void shouldReturnNullWhenPropertyIsNull() throws LoginException, JSONException {
    when(valuemap.get("count", String.class)).thenReturn(null);
    accordionModel.init();
    assertTrue(accordionModel.getAccordionList().isEmpty());
}

java.lang.NumberFormatException: For input string: "count"

"count"不能转换成Integer. 尝试改用您的count变量 ( "6")。

您应该检查列表的内容，现在我对其进行了调整以检查列表的大小是否正确。

@Test
public void shouldReturnWhenPropertyNotNull() throws LoginException, JSONException {
    when(valuemap.get("count", String.class)).thenReturn(count);
    accordionModel.init();
    assertEquals(Integer.valueOf(count), accordionModel.getAccordionList().size());
}

请注意，通常断言的参数顺序应该是expectedvs actual。
