使用Oracle数据库配置的Spring Boot @DataJpaTest无法获取数据

Question

I am new to Spring Boot. I am trying to configure the Junit Test for Spring Boot Repository. Below are the code snippet and configuration.

@RunWith(SpringRunner.class)
@DataJpaTest
@AutoConfigureTestDatabase(replace=Replace.NONE)
@ContextConfiguration(classes= ObjectAddressDaoImpl.class, loader=AnnotationConfigContextLoader.class)
@EnableAutoConfiguration(exclude=AutoConfigureTestDatabase.class)
@TestPropertySource("/application.properties")
public class AddressTest{

   @Autowired
   private AddressDao daoAddress;

   @Test
   public void testGetAddresses() {
     List<AddressEntity> addresses = daoAddress.getAddresses(99L);
     System.out.println("Addresses : " + addresses.size());
   }
}

application.properties

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@IP:Port:schema
spring.datasource.username=abcs
spring.datasource.password=abcs

spring.profiles.active=oracle

spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect
spring.jpa.hibernate.ddl-auto=validate

When I run the test it prints 0.

Kindly let me know if my configuration is correct. Any timely help appreciated!

Answer 1

It prints 0 because daoAddress.getAddress() is not returning anything. you can put a debug pointer and check on that.

So for the test you need to write asserts in your test method and check for the proper output example :-

assertTrue("A/Wing",daoAddress.getAddress());

Next you can autowire your dao class , also you can use mokito for test

This Link will help you to understand the test in spring.

Answer 2

You need to properly @Autowire the daoAddress bean into your test class so connection is properly established. If logging has been enabled, please share the logger output as well.
