Corda V1单元测试代码问题

Question

请有任何建议，但我也要git核心项目。大多数有编译错误的junit测试，有些不能正常运行。我用下面的代码在V14版本中做了Junit测试，代码没问题。但在CordaV1版本。弹出错误长鸣：

代码：

@After 
fun tearDown() { 
    net.stopNodes() 
} 
@Before 
fun setup() { 
    net = MockNetwork(false, true) 
} 

class WrapperStream(input: InputStream) : FilterInputStream(input) 

@Test

     val notaryNode = net.createNotaryNode() 
     val a = net.createPartyNode(notaryNode.network.myAddress, CordaX500Name("a","London","GB")) 
     val b = net.createPartyNode(notaryNode.network.myAddress, CordaX500Name("b","New York","US")) 

     a.internals.registerInitiatedFlow(LegalContractFlow.Acceptor::class.java) 
     b.internals.registerInitiatedFlow(LegalContractFlow.Acceptor::class.java) 

     val attachment = gInputStreamAndHash() 
     println(attachment) 

     val id = a.database.transaction { 
     a.attachments.importAttachment(attachment.inputStream) 
     } 


     assertEquals(attachment.sha256, id, "Attachment has correct SHA256 hash") 
     LegalContractFlowTests.attachList.add(id.toString()) 

     var fileName: String = "test1" 

     var legalContract: LegalContract = LegalContract(a.info.legalIdentities.first().name.toString(),LegalContractFlowTests.attachList.get(0)) 
// 

     System.out.print(legalContract) 
     var state: LegalContractState = LegalContractState(
       legalContract, 
       a.info.legalIdentities.first(), 
       b.info.legalIdentities.first()) 

     val flow = LegalContractFlow.Initiator(state, b.info.chooseIdentity(), false) 
     val future = a.services.startFlow(flow).resultFuture 


     var signedTx = future.getOrThrow() 


     for (node in listOf(a, b)) { 
      assertEquals(signedTx, node.services.validatedTransactions.getTransaction(signedTx.id)) 
     } 

    }

在琴弦V1，你需要告诉你的测试寻找合同附件时，哪些包进行扫描 - 见https://docs.corda.net/key-concepts-contract-constraints.html#testing。

这只是一个临时的样板，预计将来会被删除。实际节点也不是必需的，只适用于模拟节点。
