如何在adobe cq5中使用mockito創建頁面模擬對象，用於編寫junit

Question

我正在使用Mockito框架爲我的Adobe CQ5項目創建用於編寫junit的模擬對象。我有一些我想用JUnit測試的服務。

我發現了一個奇怪的問題，當我想用​​下面的代碼它提供了以下錯誤以便創建一個模擬Page「對象：

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

但是，這不是與其他API類新/接口

的情況下

如果我使用任何其他類來創建模擬對象，那麼它工作正常，我

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

請告訴我爲什麼只有在Adobe CQ5中的Page類的情況下才給出錯誤。

嘗試添加cq-tagging依賴項到您的項目。異常涉及到無法找到com.day.cq.tagging.Tag類。最重要的部分是：

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

檢查CQ系統控制檯依賴取景器：

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

表明，類可以在com.day.cq.cq-tagging包被發現。作爲Maven的依賴（我cq5.5實例）是：

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

如果您正在使用CQ/AEM的另一個版本，您可以有不同的版本。並稱依賴後，我可以成功運行下面的單元測試：

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); 
    } 
} 

總的來說，最小的依賴性似乎是：

<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> 

但如果你是失敗的標記，然後你可能已經得到你需要的一切。
