### Question:
JooqBatchSearchRepository implements BatchSearchRepository { @Override public boolean setState(String batchSearchId, State state) { return DSL.using(dataSource, dialect).update(BATCH_SEARCH). set(BATCH_SEARCH.STATE, state.name()). where(BATCH_SEARCH.UUID.eq(batchSearchId)).execute() > 0; } JooqBatchSearchRepository(final DataSource dataSource, final SQLDialect dialect); @Override boolean save(final BatchSearch batchSearch); @Override boolean saveResults(String batchSearchId, String query, List<Document> documents); @Override boolean setState(String batchSearchId, State state); @Override boolean setState(String batchSearchId, SearchException error); @Override boolean deleteAll(User user); @Override boolean delete(User user, String batchId); @Override BatchSearch get(String id); @Override List<BatchSearchRecord> getRecords(User user, List<String> projectsIds); @Override int getTotal(User user, List<String> projectsIds); @Override List<BatchSearchRecord> getRecords(User user, List<String> projectsIds, WebQuery webQuery); @Override BatchSearch get(User user, String batchId); @Override List<BatchSearch> getQueued(); @Override List<SearchResult> getResults(final User user, String batchSearchId); @Override List<SearchResult> getResults(User user, String batchSearchId, WebQuery webQuery); @Override boolean publish(User user, String batchId, boolean published); @Override void close();  }### Answer:
@Test public void test_set_state_unknown_batch_search() { assertThat(repository.setState("false_uuid", State.RUNNING)).isFalse(); }
