### Question:
ContentModelManager extends AbstractService implements IContentModelManager { @Override public ContentModel getContentModel(long contentModelId) { return this.getCacheWrapper().getContentModel(String.valueOf(contentModelId)); }  void setContentModelDAO(IContentModelDAO contentModelDao); void setPageManager(IPageManager pageManager); void setContentManager(IContentManager contentManager); void setCacheWrapper(IContentModelManagerCacheWrapper cacheWrapper); @Override void init(); @Override void addContentModel(ContentModel model); @Override void removeContentModel(ContentModel model); @Override void updateContentModel(ContentModel model); @Override ContentModel getContentModel(long contentModelId); @Override List<ContentModel> getContentModels(); @Override List<ContentModel> getModelsForContentType(String contentType); @Override List<ContentModelReference> getContentModelReferences(long modelId); @Deprecated @Override Map<String, List<IPage>> getReferencingPages(long modelId); @Override SmallContentType getDefaultUtilizer(long modelId);  }### Answer:
@Test public void testGetContentModel() { when(contentModelManager.getContentModel(1)).thenReturn(new ContentModel()); ContentModel model = this.contentModelManager.getContentModel(1); assertThat(model, is(not(nullValue()))); }
