新手无法运行基本的单元测试答案

【问题标题】：Newbie can't run a basic unitils test新手无法运行基本的单元测试

【问题描述】：

我正在尝试运行基本测试：

import org.junit.Test;
import org.unitils.UnitilsJUnit4;

public class SampleUnitilsTest extends UnitilsJUnit4 {

    @Test
    public void testTest() {
        assertTrue(true);
    }

}

但我得到以下堆栈跟踪：

我的 POM 包括以下内容：

    <dependency>
        <groupId>org.unitils</groupId>
        <artifactId>unitils-core</artifactId>
        <version>3.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.unitils</groupId>
        <artifactId>unitils-dbunit</artifactId>
        <version>3.1</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.unitils</groupId>
        <artifactId>unitils-orm</artifactId>
        <version>3.1</version>
        <scope>test</scope>
    </dependency>

如果这很重要，我将在 Eclipse Helios SR2 JUnit 4 测试仪中执行此操作。有什么想法吗？

【解决方案1】：

巧合的是，我也试图为我的数据库测试选择单位。我能够用 maven 2.2.1 复制你的问题。根据我之前在 maven 和 hibernate 方面的工作经验以及站点文档，这些依赖项应该就是您所需要的。

如果有什么问题，很可能是与hibernate相关的pom定义，果然在unitils-orm的pom中，以下依赖被设置为可选：

    <!-- Optional dependencies -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate</artifactId>
        <version>3.2.5.ga</version>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>3.3.1.ga</version>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>concurrent</groupId>
        <artifactId>concurrent</artifactId>
        <version>1.3.4</version>
        <optional>true</optional>
    </dependency>

添加hibernate-entitymanager确实解决了问题至于为什么pom被定义为这样，任何正当理由只有开发者知道..
