/**

 * JUnit 4 based test class, which verifies the expected functionality of
 * {@link SpringRunner} in conjunction with support for application contexts
 * loaded from Java {@link Properties} files. Specifically, the
 * {@link ContextConfiguration#loader() loader} attribute of {@code ContextConfiguration}
 * and the
 * {@link org.springframework.test.context.support.GenericPropertiesContextLoader#getResourceSuffix()
 * resourceSuffix} property of {@code GenericPropertiesContextLoader} are tested.
 * </p>
 * <p>
 * Since no {@link ContextConfiguration#locations() locations} are explicitly defined, the
 * {@code resourceSuffix} is set to &quot;-context.properties&quot;, and since default
 * resource locations will be detected by default, this test class's dependencies will be
 * injected via {@link Autowired annotation-based autowiring} from beans defined in the
 * {@link ApplicationContext} loaded from the default classpath resource: &quot;
 * {@code /org/springframework/test/junit4/PropertiesBasedSpringJUnit4ClassRunnerAppCtxTests-context.properties}
