### Question:
EnvironmentViewService { public Set<EnvironmentView> findByNamesInAccount(Set<String> names, @NotNull String accountid) { return CollectionUtils.isEmpty(names) ? new HashSet<>() : environmentViewRepository .findAllByNameInAndAccountIdAndArchivedIsFalse(names, accountid); } EnvironmentViewService(EnvironmentViewRepository environmentViewRepository, ConversionService conversionService); Set<EnvironmentView> findByNamesInAccount(Set<String> names, @NotNull String accountid); Set<EnvironmentView> findByResourceCrnsInAccount(Set<String> resourceCrns, @NotNull String accountid); Set<SimpleEnvironmentResponse> listByAccountId(String accountId); Set<EnvironmentView> findAllByAccountId(String accountId); Set<EnvironmentView> findAllByCredentialId(Long credentialId); Long getIdByName(String environmentName, String accountId); Long getIdByCrn(String crn, String accountId);  }### Answer:
@Test void findByNamesInAccount() { Set<EnvironmentView> queryResult = Set.of(); when(environmentViewRepository .findAllByNameInAndAccountIdAndArchivedIsFalse(anyCollection(), eq(ACCOUNT_ID))) .thenReturn(queryResult); assertEquals(queryResult, environmentViewServiceUnderTest.findByNamesInAccount(Set.of("name1", "name2"), ACCOUNT_ID), "findByNamesInAccount expected to give back the same result as repository mock (findAllByNameInAndAccountId)"); }
@Test void findByNamesInAccountEmptyNameList() { assertEquals(Set.of(), environmentViewServiceUnderTest.findByNamesInAccount(Set.of(), ACCOUNT_ID), "without name list the result should be empty"); }
