Sling 模型单元测试：在 SlingHttpServletRequest 中模拟 currentPage
Sling model unit tests: mock currentPage in SlingHttpServletRequest
我在测试 Sling 模型时遇到了一些问题：currentPage 由于某种原因没有被注入。
我的 Sling 模型如下所示：
@Model( adaptables = { SlingHttpServletRequest.class, Resource.class },
resourceType = MyModel.RESOURCE_TYPE)
public class MyModel {
public static final String RESOURCE_TYPE = "myproject/components/renderer";
@Inject
private Page currentPage;
// Model methods, etc.
}
我为它写了一些 JUnit 测试，像这样：
@RunWith(MockitoJUnitRunner.class)
public class MyModelTest {
@Rule
public final AemContext context = new AemContext();
@Mock
private SlingHttpServletRequest request;
private static final String RESOURCE_PATH = "/content/myproject/jcr:content/myModel";
private static final String PAGE_PATH = "/content/common/page";
private MyModel myModel;
@Before
public final void setUp() throws Exception {
context.load().json("/models/MyModel.json",RESOURCE_PATH);
context.load().json("/common-page.json", PAGE_PATH);
Resource pageResource = context.resourceResolver().getResource(PAGE_PATH);
Page page = pageResource.adaptTo(Page.class);
context.currentPage(page);
context.addModelsForClasses(MyModel.class);
when(request.getResource()).thenReturn(context.resourceResolver().getResource(RESOURCE_PATH));
myModel = request.getResource().adaptTo(MyModel.class);
}
@Test
public void simpleLoadTest(){
assertNotNull(myModel);
}
}
这是我得到的错误：

对于其他一些 Sling 模型测试，注入工作得很好，尽管对于 currentPage 我不确定如何进行。
我找不到关于在 Sling 模型中模拟 currentPage 对象的文档。
如有任何帮助，我们将不胜感激。

setUp() 方法没有抛出任何异常，也没有任何警告。

我把代码推送到了Github，你可以在下面找到项目URL
https://github.com/josebercianowhitbread/myproject
备注：
-已在 AEM 6.3 中测试
-像往常一样部署项目：mvn clean install -PautoInstallPackage
-该项目添加了一些示例页面以确保 Sling 模型按预期工作
-Sling 模型功能非常简单：它沿着内容树向上移动，直到找到 "isRootPage" 属性 设置为 true 的父节点。
如有任何问题，请告诉我。
在此先感谢您提供的任何帮助。

Justin Edelson 好心纠正并提供了测试代码。非常感谢他和 Ahmed Musallam，他一直在努力 post 直到他确保一切正常 :)
我的初始代码的两个主要问题是：
我试图模拟 Slick 请求，但应该使用来自 AemContext 的请求。
该型号未注册。
public class MyModelTest {
@Rule
public final AemContext context = new AemContext();
private MockSlingHttpServletRequest request;
AemObjectAnnotationProcessorFactory factory = new AemObjectAnnotationProcessorFactory();
AemObjectInjector aemObjectInjector = new AemObjectInjector();
private static final String RESOURCE_PATH = "/content/parent-page/jcr:content/content/renderer";
private static final String PAGE_PATH = "/content/parent-page";
private MyModel mymodel;
@Before
public final void setUp() throws Exception {
request = context.request();
context.addModelsForClasses(MyModel.class);
context.load().json("/pages/common-page.json", PAGE_PATH);
Resource pageResource =
context.resourceResolver().getResource(PAGE_PATH);
Page page = pageResource.adaptTo(Page.class);
context.currentPage(page);
context.load().json("/models/MyModel.json", RESOURCE_PATH);
context.registerInjectActivateService(factory);
context.registerService(AemObjectInjector.class, aemObjectInjector);
request.setResource(context.resourceResolver()
.getResource(RESOURCE_PATH));
mymodel = request.adaptTo(MyModel.class);
}
@Test
public void simpleLoadTest() {
assertNotNull(mymodel);
}
}
在模型中使用 @AemObject（来自 com.adobe.acs.commons.models.injectors.annotation.AemObject）而不是 @Inject 注释，以便成功注入当前页面。
您依赖 ACS 的 @AemObject 喷油器。请记住，注入器和任何 sling 注入器都是 OSGI 服务，并且您的 AEM 上下文没有注册该服务，即：它不知道 AemObjectInjector，这就是为什么您永远不会获得非空值的原因 Page.
您需要注册注入器和注释处理器：
要注册服务，请查看 wcm.io 的文档：Registering OSGi service
Note: When registering those services, make sure you register a real instance of the services and not a mocked instance. You need the real impl for the sling model injection to occur properly:
aemObjectInjector = new AemObjectInjector()
context.registerService(AemObjectInjector.class, aemObjectInjector);
