SpringBoot jUnit is not loading application-dev.xml

Question

I am using SpringBoot for latest development.Profile based configuration we have so there are 3 files are there

application-{env}.properties, env means dev,stage and prod

When I run the project locally in eclipse using -Dspring.profiles.active=dev run configuration it is picking configurations from application-dev.properties. But If I try to run a jUnit, it is expecting application.properties otherwise throwing error.I put a application.properties it is working fine.Please tell me how to configure JUnit with profile based so that which will pick application-dev.properties.Please give your input on this, thanks in advance.

@SpringBootTest
@RunWith(SpringRunner.class)
public class ProcessingServiceTest {
    @Test
    public void testlet2MeIn() throws Exception{
}
}

Answer 1

Did you try setProperty ?

@SpringBootTest
@RunWith(SpringRunner.class)
public class ProcessingServiceTest {
    public ProcessingServiceTest(){
       System.setProperty("spring.profiles.active","dev");
    }
    @Test
    public void testlet2MeIn() throws Exception{
    }
}

Answer 2

you can specify the properties files using @TestPropertySource and specify which file should be used to load properties for tests

@TestPropertySource(locations = "classpath:application-dev.properties")

Or the simplest way is to use this on your test class @ActiveProfiles("dev")
