使用 DBUnit 进行 Dao 测试：方法抛出 `'org.dbunit.dataset.NoSuchTableException

Question

我正在尝试使用 DBUnit 来测试 DAO 功能。为此，我正在尝试从 xml 文件加载数据集。但是，有些地方让我感到困惑。让我先 post 我的代码来了解一下。

public class MyDaoTest extends DatabaseTestCase
{
    private XmlDataSet loadedDataSet;

    MyDao dao;

    protected void setUp() throws Exception
    {
        dao = new CourierUploadQueueMilestonedDaoImpl();
        super.setUp();
    }

    @Override
    protected IDatabaseConnection getConnection() throws Exception
    {
        Class driverClass = Class.forName("com.mysql.jdbc.Driver");
        Connection jdbcConnection = DriverManager.getConnection("jdbc:mysql://localhost/test", "root", "root");
        return new DatabaseConnection(jdbcConnection);
    }

    @Override
    protected IDataSet getDataSet() throws Exception
    {
        FileInputStream in = new FileInputStream("dataset.xml");
        loadedDataSet = new XmlDataSet(in);
        return loadedDataSet;
    }

    protected DatabaseOperation getSetUpOperation() throws Exception
    {
        return DatabaseOperation.CLEAN_INSERT;
    }

    protected DatabaseOperation getTearDownOperation() throws Exception
    {
        return DatabaseOperation.NONE;
    }

    public void testCheckLoginDataLoaded() throws Exception
    {
        assertNotNull(loadedDataSet);
        int rowCount = loadedDataSet.getTable("person").getRowCount();
        assertEquals(2, rowCount);
    }
}

数据集文件是dataset.xml

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
    <person id="25" name="Saurabh" phone="61458972564"/>
    <person id="21" name="Saurabh" phone="61458972564"/>
</dataset>

问题：

我得到异常“方法抛出 'org.dbunit.dataset.NoSuchTableException' exception." 调试时，我没有看到 "loadedDataSet" 变量中填充了任何数据。不是配置 DatabaseOperation.CLEAN_INSERT operation in getSetUpOperation() 初始化数据集所需的内容吗？
因为我使用 xml 文件来填充数据集，为什么我需要在 getConnection() 中提供我的 MySQL 连接详细信息？它的意义何在？我可以在这里使用其他东西吗？我不希望它访问我的 mysql 数据库。我想要的行为是从 xml 文件读取，在任何插入和更新的情况下写入 xml 文件，然后一旦该方法完成就将数据集恢复为其原始内容。
我不想使用新的运算符来创建 NA 实例的 DAO class。我想使用 spring 托管实例。我试过

String[] configLocations = { "classpath:applicationContext.xml" };
ApplicationContext ctx = new ClassPathXmlApplicationContext(configLocations); personDao = (PersonDao) ctx.getBean("personDao");

不过。它给了我

Method threw   'org.springframework.beans.factory.BeanDefinitionStoreException' exception.
Unexpected exception parsing XML document from class path resource [applicationContext.xml]
detailMessage : org/springframework/core/type/AnnotatedTypeMetadata

我发现将 DBUnit 与 Spring 一起使用的最简单方法是按如下方式设置测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext-test.xml")
@DatabaseSetup("/dataset.xml")
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class,
        DbUnitTestExecutionListener.class })
public class SomeTest {


@Test
public void test1() {
 .....
}

}

您需要在 pom 中遵循 com.github.springtestdbunit.annotation.DatabaseSetup class

的依赖项

<dependency>
    <groupId>com.github.springtestdbunit</groupId>
    <artifactId>spring-test-dbunit</artifactId>
    <version>1.2.1</version>
    <scope>test</scope>
</dependency>

applicationContext-test.xml 是
