As it was mentioned @PropertySource doesn't load yaml file. As a workaround load the file on your own and add loaded properties to Environment.
Implemement ApplicationContextInitializer:
public class YamlFileApplicationContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
@Override
public void initialize(ConfigurableApplicationContext applicationContext) {
try {
Resource resource = applicationContext.getResource("classpath:file.yml");
YamlPropertySourceLoader sourceLoader = new YamlPropertySourceLoader();
PropertySource<?> yamlTestProperties = sourceLoader.load("yamlTestProperties", resource, null);
applicationContext.getEnvironment().getPropertySources().addFirst(yamlTestProperties);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
Add your initializer to your test:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class, initializers = YamlFileApplicationContextInitializer.class)
public class SimpleTest {
@Test
public test(){
// test your properties
}
}
