Spring Boot properties in 'application.yml' not loading from JUnit Test

Question

What am I doing wrong? I\'m using this little standalone App which runs and finds my src/main/resources/config/application.yml. The same configuration doesn\'t work

Answer 1

The trick to load any custom yml file in SpringBoot 2.0 w/o using @SpringBootTest

• create some yml file in test\resources
• Use ConfigFileApplicationContextInitializer and spring.config.location property

Example Code:

@RunWith(SpringRunner.class)
@ContextConfiguration(
    classes = { MyConfiguration.class, AnotherDependancy.class },
    initializers = {ConfigFileApplicationContextInitializer.class} )
@TestPropertySource(properties = { "spring.config.location=classpath:myApp-test.yml" })
public class ConfigProviderTest {
    @Autowired
    private MyConfiguration myConfiguration; //this will be filled with myApp-test.yml 

   @Value("${my.config-yml-string}")
   private String someSrting; //will get value from the yml file.

}

For JUnit 5 use the @ExtendWith(SpringExtension.class) annotation instead of @RunWith(SpringRunner.class)
