corda - 如何调试corda流测试中的类星体错误？

Question

在使用 MockNetwork 为验证公证人运行流单元测试时，我不断收到流测试失败并出现“缺少事务上下文”错误。我已经彻底验证了没有缺少@Suspendable注释的方法。在调试时，我注意到 FinalityFlow 无法成功运行 Notary.Client 流，因为后者无法在 FlowStateMachine 处挂起。从 Stack Overflow，我发现了一个关于这个错误的早期帖子。然而，添加这个标志-Dco.paralleluniverse.fibers.verifyInstrumentation=true，在输出中没有给我额外的信息。我正在使用corda 4.3开源构建我的cordapp，并按照corda文档中的建议使用quasar-0.7.10 jar。

我在这里遗漏了什么 - 我需要更改日志记录级别吗？信息是否被发送到文件中？如何正确检测流测试以获取有关执行的更多详细信息？

这是我在运行测试时看到的异常。

[INFO ] 11:36:28.623 [Mock network] flow. - Flow raised an error: Transaction context is missing. This might happen if a suspendable method is not annotated with @Suspendable annotation.. Sending it to flow hospital to be triaged.
[WARN ] 11:36:28.624 [Mock network] flow. - Caught exception from flow
java.lang.IllegalArgumentException: Transaction context is missing. This might happen if a suspendable method is not annotated with @Suspendable annotation.

MockNetwork 初始化如下。

val testCordapps = cordappPackages.map { TestCordapp.findCordapp(it) }

val mockNetwork = MockNetwork(
    MockNetworkParameters(
        cordappsForAllNodes = testCordapps,
        notarySpecs = listOf(MockNetworkNotarySpec(NOTARY_LEGAL_NAME, validating = true))
    )
)
