在Transactional DbUnit测试中拆卸时出现异常

问题描述 投票：0回答：3

测试类声明

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TestH2Config.class })
@TestExecutionListeners({
        DependencyInjectionTestExecutionListener.class,
        DbUnitTestExecutionListener.class,
        TransactionalTestExecutionListener.class
})
@TransactionConfiguration(defaultRollback = true)
@Transactional
public class BookServiceIT {
    // ... dependencies injection goes here (omitted for brevity)
    @Test
    @DatabaseSetup("/datasets/import.xml")
    public void testCase1() throws Exception {
        // .. create Book in Organization(id=2)
        // ... read and create data in database (omitted for brevity)
    }
}

测试/资源/集/ import.xml

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
  <Organization id="2" name="Gov. Library" inactive="false" />
</dataset>

用于运行测试的Maven命令：

mvn verify -T 1C

我附加了异常堆栈跟踪（仅在Codeship Linux环境中测试失败）：

我试过使用其他执行监听器（我在DbUnit documentation中找到），但我有同样的例外......

@TestExecutionListeners({
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionDbUnitTestExecutionListener.class
})

UPD。：我试图添加一个明确的拆解：在testCase（）方法的最后删除了Book。但例外情况仍然存在。

java h2 spring-test dbunit teardown

dbUnit按照数据集文件中列出的数据的相反顺序删除行。确保文件具有在具有主键/关系一侧的行之后放置外键的行。

更新：测试中存在一个书表行，因此请告诉dbUnit也要删除它。一种方法是在主表之后将外键表的空表添加到数据集文件中：

<book/>

所以dbUnit拆解操作会看到该表并清理它。

它在你的堆栈跟踪中说：

org.h2.jdbc.JdbcSQLException: Referential integrity constraint violation: "FK_JNCMPQJWFCJEXX62EA1P06VLP: ITEST.BOOK FOREIGN KEY(LIBRARY_ID) REFERENCES ITEST.ORGANIZATION(ID) (2)"; SQL statement:delete from ORGANIZATION [23503-195]

因此，当ORGANIZATION表中仍有通过BOOK外键引用ORGANIZATION表的记录时，您将从表FK_JNCMPQJWFCJEXX62EA1P06VLP中删除。

你有特殊的代码来拆除数据库吗？如果没有，您可能需要明确地编写它，或者如果您的业务需求允许，则将您的外键定义为ON DELETE CASCADE。

我通过指定type = DatabaseOperation.REFRESH改变了DbUnit的行为。现在它不会在测试后清理数据库，也没有JDBC异常。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { TestH2Config.class })
@TestExecutionListeners({
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionDbUnitTestExecutionListener.class
})
@Transactional
public class BookServiceIT {
    // ... dependencies injection goes here (omitted for brevity)
    @Test
    @DatabaseSetup(value = "/datasets/import.xml", type = DatabaseOperation.REFRESH)
    public void testCase1() throws Exception {
        // .. create Book in Organization(id=2)
        // ... read and create data in database (omitted for brevity)
        // .. delete the Book
    }
}

请参阅@DatabaseSetup文档。
