### Question:
MinimalExample { public Book deserializeBook() { Book book = new Book("SHDUJ-4532", "Fun with Java", "Alex Theedom"); Jsonb jsonb = JsonbBuilder.create(); String json = jsonb.toJson(book); book = jsonb.fromJson(json, Book.class); return book; }  String serializeBook(); Book deserializeBook();  }### Answer:
@Test public void givenJSONString_shouldDeserializeToBookObject() { Book expectedBook = new Book("SHDUJ-4532", "Fun with Java", "Alex Theedom"); MinimalExample minimalExample = new MinimalExample(); Book actualBook = minimalExample.deserializeBook(); assertThat(actualBook).isEqualTo(expectedBook); }
