Duplicated assertion method with target class implementing method from interface

> - We have an Interface X which has method called id()
> - We implement this Interface X in several classes. The typical implementation is
> - `String id = "someId"; public String id() { return id; }`
> - When AssertJ creates the *Assert classes it creates the method `hasId` twice, e.g.

> /**
> * Verifies that the actual Data's id is equal to the given one.
> * @param id the given id to compare the actual Data's id to.
> * @return this assertion object.
> * @throws AssertionError - if the actual Data's id is not equal to the given one.
> */
> public S hasId(String id) {
> // check that actual Data we want to make assertions on is not null.
> isNotNull();
>
> // overrides the default error message with a more explicit one
> String assertjErrorMessage = "\nExpecting id of:\n <%s>\nto be:\n <%s>\nbut was:\n <%s>";
>
> // null safe check
> String actualId = actual.getId();
> if (!Objects.deepEquals(actualId, id)) {
> failWithMessage(assertjErrorMessage, actual, id, actualId);

Non viene indicato alcun file sorgente né alcun test. Inizia individuando il percorso del generatore che trasforma i metodi dell’interfaccia e dell’implementazione in metodi di asserzione, quindi riproduci il caso con un’interfaccia id() e una classe che la implementa. Il lavoro è completato quando la generazione non produce più metodi hasId duplicati e il comportamento è coperto da un test di regressione.

Scritto dal modello di indicizzazione a partire dal testo della issue.
