Read @PropertySource without Spring Boot Application

Question

I have a multi module Spring Boot project with the following structure:

MyAppModule
- src/main/java/Application.java
- ...
IntegrationTests
- src/test/java/integrationTest.java

The IntegrationTest module is testing the MyAppModule. The IntegrationTest module does not have a main package. Therefore there is no Spring Application. It has just the test package.

Nevertheless I would like to read in the application.yaml for some properties but I'm not able to because the attributes are always null:

@Configuration
@PropertySource("classpath:application.yaml")
public class IntegrationTest {

  @Value("${app.url}")
  private String appUrl;

}

Isn't it possible to use the @Value annotation without having a Spring Application (main with SpringApplication.run etc.)?

@PropertySource is only for .properties file not for loading .yaml files. Yes it is possible, no it isn't working (neither in Spring Boot) for YAML files. — M. Deinum

Why not just @ConfigurationProperties?

@Configuration
@ConfigurationProperties(prefix = "app")
public class IntegrationTest {

 private String url;

 }

Add Integration tests base package for component scanning in spring configuration.

@ComponentScan("basePackage1,basePackage2....etc")

Thanks for all responses. Solved it with the following code and a SpringBootApplication was necessary.

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class IntegrationTest {

 @Value("${app.url}")
 private String url;

 }
