Question

M13からM14にアップグレードすると、MockNetworkでOracleをテストするときに次のランタイム例外が発生します。フィルタリングされたトランザクションを構築しようとしているときに例外が発生したように見えます。 M14では、データベースをCordaPersistence = configureDatabase（makeTestDataSourceProperties（））に変更しました。それを動作させる方法はありますか？

@Test 
    fun `sign - ok`() { 
     database.transaction { 
      val fxRateRequest = FXRateRequest(USD, EUR/*, LocalDate.now(), Tenor("1D")*/) 
      val now = Instant.now() 
      val fxRateResponse = FXRateContract.Sign(fxRateRequest, BigDecimal(0.8), TimeWindow.between(now, now.plusSeconds(30))) 
      val command = Command(fxRateResponse, listOf(oracle_KeyPair.public)) 
      val state = FXRateContract.State(ALICE) 
      val wtx: WireTransaction = TransactionType.General.Builder(DUMMY_NOTARY) 
        .withItems(state, command) 
        .toWireTransaction() 
      val ftx: FilteredTransaction = wtx.buildFilteredTransaction(Predicate { x -> /*filterCmds*/fixCmdFilter(x) }) 

      val signature = oracle.sign(ftx) 
      /** Post M13.0, we can use this instead of the assert */ 
//   wtx.checkSignature(signature) 

      assert(signature.verify(ftx.rootHash.bytes)) 
     } 
    }

Answer 1

我々が使用するシリアル化フレームワークは、将来の変更の準備のためにM14に注入しました。 MockNetworkはこれを処理する必要がありますが、あなたが与えたスタックトレースには表示されません。スタンドアロンユニットテストの場合は、テストクラスをnet.corda.testing.TestDependencyInjectionBaseまで拡張してください。各テストは初期化とリセットのステップでラップされ、これを注入します。

そのクラスから拡張できない場合は、その動作を常に複製できますが、クラスを拡張することは、今後他のコンポーネントを挿入する必要がある場合には、将来の証明になります。
