java-与DBUnit集成测试Spring存储库层

2022-11-30 22:29:33

我一直关注着Petri Kainulainen的this非常有用的博客文章,以使用spring-data-jpa和DBUnit为我的Spring存储库代码编写集成测试.

我有这样设置我的bean上下文XML

<?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);

}

我的测试班就这样建立了

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());
  }

}

我期望@DatabaseSetup批注进行配置,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.

这似乎什么也不做(即数据库保持空白,没有表或数据),并且我的第二项测试testFindByDirectorIdWhendirectorIsFound失败,因为返回的导向器为null.我想念什么？

编辑1好的,我已经有了一些进展,现在我已经创建了表,但是没有数据.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弄清楚为什么它没有用数据填充我新创建的表

编辑2将JpaTransactionManager bean和tx注释驱动添加到上下文

<?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>

编辑3好的,在将slf4j包含在我的maven依赖项中并创建设置了DEBUG级别的log4j.properties文件之后,我设法启用了DEBUG级别.

而且我在日志中看到了这一点,也许可以提供一个线索？

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]

我相信这是参考我测试代码的这一部分

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

解决方法:

连同我对原始帖子所做的编辑,似乎我在Maven pom.xml中缺少了DBUnit依赖项.添加以下内容后,我现在有了数据,感谢Petri和Phil的帮助！

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