使用DBUnit集成測試Spring存儲庫層

Question

我一直在關注Petri Kainulainen的這篇非常有用的博客文章，使用spring-data-jpa和DBUnit為我的Spring存儲庫代碼編寫集成測試。

我有這樣的bean上下文XML設置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <context:property-placeholder location="file:src/main/webapp/WEB-INF/config/application-test.properties"
        ignore-resource-not-found="false" />

    <bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource">
        <property name="driverClass" value="${db.driver}" />
        <property name="jdbcUrl" value="${db.url}" />
        <property name="username" value="${db.username}" />
        <property name="password" value="${db.password}" />
    </bean>
    <bean id="directorRepository" name="directorRepositoryMock" class="org.mockito.Mockito"
        factory-method="mock">
        <constructor-arg value="com.tvfreakz.repository.DirectorRepository" />
    </bean>

</beans>

我的數據集XML具有以下內容

<!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>

這是存儲庫界面

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);

}

我的測試類就是這樣設置的

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注釋采用我的配置並將所有表和數據插入到我的由dataSource bean配置的測試數據庫中。

這似乎什么也沒做（即數據庫保持空白，沒有表或數據），我的第二個測試testFindByDirectorIdWhendirectorIsFound失敗，因為導致返回的是null。 我錯過了什么？

編輯1好我有一些進展，我現在有表創建，但沒有數據。 問題是我不應該使用模擬存儲庫。 我不得不將我的上下文XML更新為以下內容。 因此，下一個問題是嘗試找出為什么它沒有用數據填充我新創建的表

編輯2 JpaTransactionManager bean和tx注釋驅動添加到上下文

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:jpa="http://www.springframework.org/schema/data/jpa"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <context:property-placeholder location="file:src/main/webapp/WEB-INF/config/application-test.properties"
        ignore-resource-not-found="false" />

<jpa:repositories base-package="com.tvfreakz.repository" />

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="punit"/>
    <property name="dataSource" ref="dataSource"/>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true"/>
        </bean>
    </property>
    <property name="jpaPropertyMap">
        <map>
            <entry key="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
            <entry key="hibernate.hbm2ddl.auto" value="update"/>
            <entry key="hibernate.format_sql" value="true"/>
            <entry key="hibernate.show_sql" value="true"/>
        </map>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

<tx:annotation-driven transaction-manager="transactionManager"/>

    <bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource">
        <property name="driverClass" value="${db.driver}" />
        <property name="jdbcUrl" value="${db.url}" />
        <property name="username" value="${db.username}" />
        <property name="password" value="${db.password}" />
    </bean>

</beans>

編輯3確定在我的maven依賴項中包含slf4j並創建了一個設置了DEBUG級別的log4j.properties文件后，我設法啟用了DEBUG級別。

我在日志中看到了這一點，這或許給出了一個線索？

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]

我相信這是參考我測試代碼的這一部分

@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
  DirtiesContextTestExecutionListener.class,
  TransactionalTestExecutionListener.class,
  DbUnitTestExecutionListener.class })

Answer 1

隨着我對原始帖子的編輯，似乎我在Maven pom.xml中缺少DBUnit依賴項。 添加以下內容后，我現在有了數據，感謝Petri和Phil的幫助！

    <dependency>
        <groupId>org.dbunit</groupId>
        <artifactId>dbunit</artifactId>
        <version>2.5.0</version>
    </dependency>
