NoSQLUnit MongoDB测试:Spring Data MongoDB方法

我正在尝试在我的一些Spring应用程序测试中使用this库,但没有取得多大成功。 Spring Data MongoDB似乎是supported,但我没有设法让它工作。 examples没有完全遵循@Repository方法。

假设我有一个DummyClass POJO:

@Document(collection = DummyClass.ITEMS_COLLECTION_NAME)
public class DummyClass {

    public static final String ITEMS_COLLECTION_NAME = "dummy";

    //Maps _id mongodb internal field
    private BigInteger id;

    private String a;
    private String b;

    public DummyClass() {
        super();
    }

    public DummyClass(String a, String b) {
        this.a = a;
        this.b = b;
    }

    public String getA() {
        return a;
    }

    public void setA(String a) {
        this.a = a;
    }

    public String getB() {
        return b;
    }

    public void setB(String b) {
        this.b = b;
    }

}

我有各自的存储库接口和自定义接口/实现:

@Repository
public interface DummyClassRepository extends MongoRepository<DummyClass, Long>, DummyClassRepositoryCustom {
}

public interface DummyClassRepositoryCustom {
    /* My dummy methods declaration */
}

public class DummyClassRepositoryImpl implements DummyClassRepositoryCustom{
    /* My dummy methods implementation */
}

这就是我的测试环境的样子(简化):

<?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:mongo="http://www.springframework.org/schema/data/mongo"
       xsi:schemaLocation=
          "http://www.springframework.org/schema/context
          http://www.springframework.org/schema/context/spring-context-3.0.xsd
          http://www.springframework.org/schema/data/mongo
          http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <context:component-scan base-package="org.company.project.data.*"/>

    <!-- Fongo config (used by NoSQL-Unit) -->
    <bean name="fongo" class="com.foursquare.fongo.Fongo">
        <constructor-arg value="InMemoryMongo" />
    </bean>
    <bean id="mongo" factory-bean="fongo" factory-method="getMongo" />

    <mongo:db-factory id="mongoDbFactory" mongo-ref="mongo" />

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg ref="mongoDbFactory"/>
    </bean>

    <mongo:repositories base-package="org.company.project.data.repositories.mongodb"/>

    <!-- Some other beans declaration -->

</beans>

显然,我的MongoDB存储库位于org.company.project.data.repositories.mongodb

之下

问题是我无法将某个.json加载到内存中的MongoDB实例。到目前为止我所拥有的:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/test-context.xml"})
public class MyTest {

    private static Logger logger = Logger.getLogger(MyTest.class);

    @Autowired
    private ApplicationContext applicationContext;

    @Rule
    public MongoDbRule mongoDbRule = newMongoDbRule().defaultSpringMongoDb("test");

    @Autowired
    private DummyClassRepository dummyClassRepository;

    @Test
    @UsingDataSet(locations = {"/dummy.json"}, loadStrategy = LoadStrategyEnum.CLEAN_INSERT)
    public void myTest(){
         logger.info(dummyClassRepository.findAll().size());
         assert(false);
    }

}

.json文件的内容遵循文档中指定的格式,但无论我指定什么,在启动测试方法时,集合始终为空。例如,此.json文件的示例可能是:

{
    "dummy": [
        {
            "_class": "org.company.project.data.model.DummyClass",
            "_id": "51557362e4b083f9e619f99c",
            "a": "a",
            "b": "b"
        },
        {
            "_class": "org.company.project.data.model.DummyClass",
            "_id": "51557362e4b083f9e619f99d",
            "a": "c",
            "b": "d"
        }
    ]
}

令我震惊的是,曾经,在测试方法本身中,我能够毫无问题地将我的虚拟实例添加到数据库,这基本上告诉我存储库实际上工作正常。

是否有人使用此JUnit扩展,可以为我提供一些想法,说明为什么指定的数据集没有加载到数据库中?

提前谢谢!

Jaranda,

似乎您的spring存储库和nosqlunit正在处理不同的数据库。尝试修改弹簧配置以使用相同的nosqlunit数据库。

 <mongo:db-factory id="mongoDbFactory" mongo-ref="mongo" dbname="test" />
