什么是最好的实践方式做单元测试和春天？ 我想结合TestNG的＆jmockit与Spring 3不坏，所以这是我在做什么的权利，但如果我偏离方向选择的工具为我的新的Spring项目，请告诉我的时候了。 :-)
不管怎么说，我已经创建了一个我想测试一个实体，但我不知道如何实际运行从Spring上下文TestNG的。 我创建了一个简单的测试类
package com.mydomain.data.entities.test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.Assert;
import org.testng.annotations.*;
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class SimpleTest extends AbstractTestNGSpringContextTests {
@Autowired
private ApplicationContext applicationContext;
@BeforeClass
protected void setUp() throws Exception {
Assert.assertNotNull(applicationContext);
}
@Test
public void testNothing() {
}
}
与进口的applicationContext.xml豆建立模型和业务层。 首先要明确的，我想它从项目/的WebRoot / WEB-INF使用applicationContext.xml的，而本次测试的源居项目/ src目录/ COM / MYDOMAIN /数据/实体/测试，但我相信， /applicationContext.xml会给我的项目/ src目录，一样的类路径：这是正确的吗？
此外，现在我用我的web应用程序将使用模式和业务层，我应该期待它的行为类似。 但是，当我启动TestNG的在测试中，最高审计机关：类org.hibernate.cfg.ExtendedMappings有接口org.hibernate.cfg.Mappings为超类：

这是什么和为什么我得到这个？ 任何线索？
我的SessionFactory的是这样的
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="annotatedClasses">
<list>
<!-- Entity classes from package com.mydomain.data.entities -->
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
