### Question:
JpaOAuthConsumerStoreRepository implements OAuthConsumerStoreRepository { @Override public void delete(OAuthConsumerStore item) { manager.remove(converter.convert(item)); }  @Override Class<? extends OAuthConsumerStore> getType(); @Override OAuthConsumerStore get(String id); @Override OAuthConsumerStore save(OAuthConsumerStore item); @Override void delete(OAuthConsumerStore item); @Override List<OAuthConsumerStore> getAll(); @Override List<OAuthConsumerStore> getLimitedList(int offset, int limit); @Override int getCountAll(); @Override OAuthConsumerStore findByUriAndServiceName(String gadgetUri, String serviceName);  }### Answer:
@Test @Transactional(readOnly=false) @Rollback(true) public void delete() { OAuthConsumerStore oAuthConsumerStore = repository.get(VALID_ID.toString()); assertThat(oAuthConsumerStore, is(notNullValue())); repository.delete(oAuthConsumerStore); oAuthConsumerStore = repository.get(VALID_ID.toString()); assertThat(oAuthConsumerStore, is(nullValue())); }
