我正在学习springboot并创建了一个简单的springboot应用程序。我希望它在运行单元测试时使用嵌入式mongoDB,而在应用程序的其余部分使用外部mongoDB。但是它使用外部mongoDB进行单元测试而不是嵌入式测试。 我在POM中有两个依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
我的属性文件包含以下内容:
# MongoDB properties
mongo.db.name=person_testDB
mongo.db.url=localhost
#external Mongo url
spring.data.mongodb.uri=mongodb://localhost:27017/personDB
我有一个配置文件(MongoDBConfig.java),其中包含嵌入式MongoDB配置:
@EnableMongoRepositories
public class MongoDBConfig {
@Value("${mongo.db.url}")
private String MONGO_DB_URL;
@Value("${mongo.db.name}")
private String MONGO_DB_NAME;
@Bean
public MongoTemplate mongoTemplate() {
MongoClient mongoClient = new MongoClient(MONGO_DB_URL);
MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, MONGO_DB_NAME);
return mongoTemplate;
}
}
以下是我的PersonService.java
课程:
@Service
public class PersonService {
private static final Logger logger = LoggerFactory.getLogger(PersonService.class);
@Autowired
MongoTemplate mongoTemplate;
public void savePerson(Person person) {
String name = person.getName();
String collectionName = name.substring(0, 1);
mongoTemplate.save(person, collectionName);
}
}
我对PersonsService类的单元测试如下:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {MongoDBConfig.class})
@SpringBootTest(classes = PersonService.class)
@DataMongoTest
public class PersonServiceTest {
@Autowired
PersonService personService;
MongodForTestsFactory factory;
MongoClient mongo;
@Before
public void setup() throws Exception {
factory = MongodForTestsFactory.with(Version.Main.PRODUCTION);
mongo = factory.newMongo();
}
@After
public void teardown() throws Exception {
if (factory != null)
factory.shutdown();
}
@Test
public void testSave(){
Person person = new Person("Bob Smith " , 25);
personService.savePerson(person);
}
}
它在外部MongoDB中正确创建了集合名称和文档名称,这不是我想要的。如何将unitTests限制为嵌入式Mongo?
答案 0 :(得分:4)
另一种方法是在测试中运行整个spring boot应用程序。在这种情况下,将自动发现spring boot应用程序,并且将通过Spring Boot
下载并启动嵌入式mongoDB@RunWith(SpringRunner.class)
@SpringBootTest
public class YourSpringBootApplicationTests {
08:12:14.676 INFO EmbeddedMongo:42 - 注意:noprealloc可能会受伤 许多应用程序中的性能08:12:14.694 INFO EmbeddedMongo:42 - 2017-12-31T08:12:14.693 + 0200 I CONTROL [initandlisten] MongoDB 开始:pid = 2246 port = 52299 08:12:22.005 INFO连接:71 - 打开连接[connectionId {localValue:2,serverValue:2}]到 本地主机:52299
如果是您的示例,您可以修改代码以便在不同的端口上启动嵌入式Mongo:
添加test / resoures / test.properties文件以覆盖application.properties中的属性
mongo.db.name=person_testDB
mongo.db.url=localhost
mongo.db.port=12345
修改MongoDBConfig:添加MONGO_DB_PORT字段
@EnableMongoRepositories
public class MongoDBConfig {
@Value("${mongo.db.url}")
private String MONGO_DB_URL;
@Value(("${mongo.db.port:27017}"))
private int MONGO_DB_PORT;
@Value("${mongo.db.name}")
private String MONGO_DB_NAME;
@Bean
public MongoTemplate mongoTemplate() {
MongoClient mongoClient = new MongoClient(MONGO_DB_URL, MONGO_DB_PORT);
MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, MONGO_DB_NAME);
return mongoTemplate;
}
}
修改测试类: 删除@DataMongoTest注释。此注释强制启动嵌入式mongoDB实例
static MongodExecutable mongodExecutable;
@BeforeClass
public static void setup() throws Exception {
MongodStarter starter = MongodStarter.getDefaultInstance();
String bindIp = "localhost";
int port = 12345;
IMongodConfig mongodConfig = new MongodConfigBuilder()
.version(Version.Main.PRODUCTION)
.net(new Net(bindIp, port, Network.localhostIsIPv6()))
.build();
mongodExecutable = null;
try {
mongodExecutable = starter.prepare(mongodConfig);
mongodExecutable.start();
} catch (Exception e){
// log exception here
if (mongodExecutable != null)
mongodExecutable.stop();
}
}
@AfterClass
public static void teardown() throws Exception {
if (mongodExecutable != null)
mongodExecutable.stop();
}
另一种方法是使用MongoRepository和init嵌入式Mongo作为测试@Configuration类的一部分:这里概述了:How do you configure Embedded MongDB for integration testing in a Spring Boot application?
