Hyperledger锯齿XO测试用例在执行时挂起

Question

我尝试使用nose2-3来运行锯齿xo tp单元测试，但是代码挂起了。当按下Ctrl-C组合键时，将显示以下内容。基本上，TP测试用例调用注册模拟验证器，并且该调用永远不会返回，因为ZMQ轮询器正在等待某些东西。

我使用的是Ubutnu 16 LTS，使用的是Python 3.5.2，上周使用的是hyperledger/sawtooth core，所以我用最新的代码运行了一个简单的配置。

我在这里做错了什么？

谢谢。

您是否尝试过在同一目录中运行Dockerfile-tests-installed？这些测试主要用于自动化使用，并设置了完整的测试环境。请参阅顶级github目录中的Jenkinsfile。

如果你只是想运行并试用它，你可以在Ubuntu或Docker中按照以下说明运行它：https://sawtooth.hyperledger.org/docs/core/releases/latest/app_developers_guide/installing_sawtooth.html

基本上，只需安装锯齿、Docker、docker-compose，然后运行：docker-compose -f sawtooth-default.yaml up

然后可以使用以下命令从Docker shell运行锯齿命令：docker exec -it sawtooth-shell-default bash
