In this recipe, we will stub a void method that doesn't return a value, so it throws an exception.
For this recipe, our system under test will be a PersonProcessor class that, for simplicity, does only one thing: it delegates the process of saving person to the PersonSaver class. As shown in the following code, in case of success, true is returned; otherwise, false is returned:
public class PersonProcessor {
private final PersonSaver personSaver;
public PersonProcessor(PersonSaver personSaver) {
this.personSaver = personSaver;
}
public boolean process(Person person) {
try {
personSaver.savePerson(person);
return true;
} catch (FailedToSavedPersonDataException e) {
System.err.printf("Exception occurred while trying save person data [%s]%n", e);
return false;
}
}
}
