Question

我正在尝试使用DBUnit来测试DAO功能。我想，我试图从xml文件加载数据集。但是，有些问题让我感到困惑。让我先发布我的代码以获得一些观点。

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);
    }
}

datset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＆＃34;方法抛出'org.dbunit.dataset.NoSuchTableException' exception." 当我调试时，我看不到"loadedDataSet"变量中填充的任何数据。是否未配置DatabaseOperation.CLEAN_INSERT operation in getSetUpOperation()初始化数据集所需的内容？
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连接细节？它的意义是什么？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文件中读取，在任何插入和更新的情况下写入xml文件，然后在方法完成后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DAO类的na实例。我想使用spring托管实例。我试着做了

String [] configLocations = {＆＃34; classpath：applicationContext.xml＆＃34; };
ApplicationContext ctx = new ClassPathXmlApplicationContext（configLocations）; personDao =（PersonDao）ctx.getBean（＆＃34; personDao＆＃34;）;

然而。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

我发现在Spring中使用DBUnit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() {
 .....
}

}

你需要在你的pom中跟踪com.github.springtestdbunit.annotation.DatabaseSetup类的依赖

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

applicationContext-test.xml是

希望这有帮助。
