从M13升级到M14时，在MockNetwork中测试oracle时出现以下运行时异常。看起来在尝试构建过滤的事务时发生异常。对于M14，我将数据库更改为CordaPersistence = configureDatabase（makeTestDataSourceProperties（））。有没有办法让它发挥作用？
@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))
}
}
异常

答案 0 :(得分：3)
我们使用的序列化框架在M14中注入，为将来的变化做准备。 MockNetwork应该为你处理这个问题，但是我没有在你给出的堆栈跟踪中看到这一点。对于独立单元测试，请尝试让测试类扩展net.corda.testing.TestDependencyInjectionBase，这将在初始化和重置步骤中包装每个测试，以便为您注入。
如果你不能从那个类扩展，那么你总是可以复制它的行为，但是扩展这个类将是未来何时以及是否需要注入其他组件的未来证据。
