corda - Corda 单元测试因缺少 @Suspendable 而失败

问题描述

在 Corda Enterprise 4.1 上运行单元测试时，以前的工作流单元测试会崩溃，并出现以下异常：

java.lang.IllegalArgumentException: Transaction context is missing. This might happen if a suspendable method is not annotated with @Suspendable annotation.

所有方法都正确包含@Suspendable注释。是什么导致流量测试失败？

解决方案

确保您的 Cordapp 中包含正确版本的 Quasar。该版本已随 Corda 4 更改，请查看所需版本的 Quasar 文档：https ://docs.corda.r3.com/app-upgrade-notes-enterprise.html#re-compiling-for-release

对于 Corda 4.1，这将是ext.quasar_version = '0.7.11_r3'.
