}
}
@Test
public void testMenu() {
log.debug("About to read the Resource file: menu.txt ");
Resource resource = context.getResource("classpath:META-INF/data/menu.txt");
try{
InputStream stream = resource.getInputStream();
Scanner scanner = new Scanner(stream);

}catch(IOException e){
e.printStackTrace();
}
}
The Spring Framework has a utility package, org.springframework.core.io, that contains several helpers for

that will locate your resource file so you can print it out into the console. If you run your unit test using
gradle :ch05:test
