Answer 1

SpringApplicationConfiguration is deprecated in spring [Spring Boot v1.4.x] and removed in: [Spring Boot v1.5.x]. So, this is an updated answer.

MyTestClass class is like:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.ConfigFileApplicationContextInitializer;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import static org.assertj.core.api.Assertions.assertThat;

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = MyConfiguration.class, initializers = ConfigFileApplicationContextInitializer.class)
public class MyTestClass {
    @Autowired
    private MyYmlProperties myYmlProperties;

    @Test
    public void testSpringYmlProperties() {
        assertThat(myYmlProperties.getProperty()).isNotEmpty();
    }
}

MyYmlProperties class is like:

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix = "my")
public class MyYmlProperties {
    private String property;
    public String getProperty() { return property; }
    public void setProperty(String property) { this.property = property; }
}

My application.yml is like:

my:
  property: Hello

Finally MyConfiguration is really empty :-) you can fill it with what you want:

import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableConfigurationProperties(value = MyYmlProperties.class)
public class MyConfiguration {
}
