使用 DBUnit 集成测试 Spring 存储库层
Integration testing Spring repository layer with DBUnit
我一直在关注 Petri Kainulainen 的 this 非常有用的博客 post，使用 spring-data-jpa 和 DBUnit 为我的 Spring 存储库代码编写集成测试.
我的 bean 上下文 XML 是这样设置的
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean id="directorRepository" name="directorRepositoryMock" class="org.mockito.Mockito"

<constructor-arg value="com.tvfreakz.repository.DirectorRepository" />
</bean>
</beans>
我的数据集 XML 具有以下内容
<!DOCTYPE dataset SYSTEM "my-dataset.dtd">
<dataset>
<director directorid="1" director="Ridley Scott" />
<director directorid="2" director="James Cameron" />
<director directorid="3" director="David Fincher" />
<director directorid="4" director="Jean-Pierre Jeunet" />
</dataset>
这是存储库界面
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import com.tvfreakz.model.entity.Director;
@Repository("directorRepository")
public interface DirectorRepository extends JpaRepository<Director, Long> {
Director findByDirectorId(Long directorId);
}
我的测试class是这样设置的
import static org.junit.Assert.assertNull;
import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.support.DirtiesContextTestExecutionListener;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import com.github.springtestdbunit.DbUnitTestExecutionListener;
import com.github.springtestdbunit.annotation.DatabaseSetup;
import com.tvfreakz.model.entity.Director;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"file:src/main/webapp/WEB-INF/config/testMVCContext.xml"})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@DatabaseSetup("testDataset.xml")
public class ITDirectorRepositoryTest {
@Autowired
private DirectorRepository repository;
@Test
public void testFindByDirectorIdWhenNoDirectorFound() {
Director director = repository.findByDirectorId(10L);
assertNull(director);
}
@Test
public void testFindByDirectorIdWhendirectorIsFound() {
Director director = repository.findByDirectorId(1L);
assertEquals("Ridley Scott", director.getDirectorName());
}
}
我期待 @DatabaseSetup 注释采用我的配置并将所有表和数据插入设置到由 dataSource bean 配置的测试数据库中。
这似乎什么都不做（即数据库保持空白，没有表或数据），我的第二个测试 testFindByDirectorIdWhendirectorIsFound 失败，因为返回的 director 为空。我错过了什么？
编辑 1 好的，我有一些进展，我现在创建了表，但没有数据。问题是我不应该使用模拟存储库。我必须将上下文 XML 更新为以下内容。所以下一个问题是尝试找出为什么它没有用数据填充我新创建的表

编辑 3 好的，在我的 Maven 依赖项中包含 slf4j 并创建一个设置了 DEBUG 级别的 log4j.properties 文件后，我设法启用了 DEBUG 级别。
我在日志中看到了这个，这也许提供了线索？
14:47:05,670 INFO TestContextManager:242 - Could not instantiate TestExecutionListener [com.github.springtestdbunit.DbUnitTestExecutionListener]. Specify custom listener classes or make the default listener classes (and their required dependencies) available. Offending class: [org/dbunit/dataset/IDataSet]
我相信这是参考了我的这部分测试代码
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class })
随着我对原始 post 所做的编辑，我似乎在我的 Maven pom.xml 中缺少 DBUnit 依赖项。添加以下内容后，我现在有了数据，谢谢 Petri 和 Phil 的帮助！
