  1. I have a java/spring-boot class
@SpringBootApplication
@ComponentScan(value = "ignore")
@RunWith(SpringRunner.class)
public class MyApplication {
   @Bean
   YAMLConfig myeadFromYMLFile() {
      return new YAMLConfig();
   }
   public static void main(String[] args) throws InterruptedException {
      ConfigurableApplicationContext context = 
         SpringApplication.run(MyApplication.class, args);
      YAMLConfig myBean = context.getBean(YAMLConfig.class);
      myBean.doSomething();
      myBean.printApi();
   }
}
  1. And have config file, what reads data from yml file
@Configuration
@EnableConfigurationProperties
public class YAMLConfig {
   @Value("${refresh.rate}")
   private int refreshRate;
   @Value("${datasource.apiUrl}")
   private String apiUrl;
   public void doSomething() {
      System.out.printf("Refresh Rate : %s%n", refreshRate);
   }
   public void printApi() {
      System.out.printf("Refresh Rate : %s%n", apiUrl);
   }
   public String getApiUrl() {
      return apiUrl;
   }
}

Question: when I run class MyApplication in src/java/main everything is cool. BUT: when I run this class in src/java/test it fails

Error starting ApplicationContext.

P.S.I have spring-boot-starter-web dependency. With @SpringBootTest I got this:

javaspring-boot
can you include your test code too? – Nitishkumar Singh
You say you run MyApplication class both in src/java/test and in src/java/main? Is it a typo, or you don't follow the Maven Standard Directory Layout? – Boris
It is standart maven project, and this main method is a test. And this method run from main/ but not run from test/, maybe I forgot about some annotation or use not the right annotation. Or if you know how to do this rightly I will be grateful for your advise. – Cyril Krasnobaiev
I'm not getting why there is a need of having a main in your test class. As said by Boris you should not mix two things. For your application, you can have main. For test classes @Runwith and @Test should be sufficient – Ganesh Satpute
