Spring: Can't override properties with @ConfigurationProperties for test

Question

I'm trying to configure property for test, using @ConfigurationProperties.

My config-class with properties:

 @Data
 @Configuration
 @ConfigurationProperties(prefix = "data")
 public class TestFileSettings {
     private String dockerMountPath;
}

Property-file "application-test.properties" contains:

data.docker_mount_path=testMountHostDirectory/

And test-class:

  @ActiveProfiles("test")
  @TestPropertySource(locations = "classpath:application-test.properties")
  @EnableConfigurationProperties(value = {TestFileSettings.class})
  @RunWith(SpringRunner.class)
  @SpringBootTest()
  public class PropertyAcessTest {
       @Autowired
       private TestFileSettings testFileSettings;

       @Test()
       public void testPropertyAcess() {        
       String getDockerMountPath = testFileSettings.getDockerMountPath();
       assertEquals("testMountHostDirectory/", getDockerMountPath)
     {

But I get the following error:

  error: cannot find symbol
    String getDockerMountPath = testFileSettings.getDockerMountPath();
                                                ^
 symbol:   method getDockerMountPath()
 location: variable testFileSettings of type TestFileSettings

What am I doing wrong?
