Question

我正在使用Mockito框架来创建用于为我的Adobe CQ5项目编写junits的模拟对象。我有一些我想用JUnit测试的服务。

当我想使用下面的代码创建一个模拟Page'对象时，我发现了一个奇怪的问题，它给出了以下错误：

Page pageObj = Mockito.mock(Page.class);

但其他api classess / interfaces

并非如此

如果我使用任何其他类来创建模拟对象，那么它对我来说很好

`PageManager page = mock(PageManager.class)`;//or i use annotations

请告诉我为什么它仅在Adobe CQ5中的Page类的情况下给我错误。

尝试将cq-tagging依赖项添加到项目中。例外情况与无法找到com.day.cq.tagging.Tag类有关。重要的是：

java.lang.NoClassDefFoundError: [Lcom/day/cq/tagging/Tag;

检查cq系统控制台依赖项查找器：

http://localhost:4502/system/console/depfinder?plugin.find=com.day.cq.tagging.Tag&plugin.submit=Find

显示该类可以在com.day.cq.cq-tagging包中找到。作为maven依赖（在我的cq5.5实例上）是：

<dependency>
  <groupId>com.day.cq</groupId>
  <artifactId>cq-tagging</artifactId>
  <version>5.5.0</version>
  <scope>provided</scope>
</dependency>

如果您使用的是其他版本的CQ / AEM，则可能有不同的版本。添加该依赖项后，我可以成功运行以下单元测试：

import static org.mockito.Mockito.mock;

import org.junit.Test;
import com.day.cq.wcm.api.Page;

public class PageUnitTest {

    @Test
    public void shouldMockPageObject() {
        Page page = mock(Page.class);
    }
}

总体而言，最小依赖关系似乎是：

<dependency>
    <groupId>com.day.cq.wcm</groupId>
    <artifactId>cq-wcm-api</artifactId>
    <version>5.5.0</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.apache.sling</groupId>
    <artifactId>org.apache.sling.api</artifactId>
    <version>2.2.4</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.day.cq</groupId>
    <artifactId>cq-commons</artifactId>
    <version>5.5.0</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.day.cq</groupId>
    <artifactId>cq-tagging</artifactId>
    <version>5.5.0</version>
    <scope>provided</scope>
</dependency>

虽然如果你没有标记，那么你可能已经得到了你需要的一切。
