如何在VSTS发布步骤上运行VisualStudio2017 dotnet测试项目

Question

有人知道如何使用dotnet测试在VSTS上运行测试项目吗？

我的情况就是这样。我有一个简单的MVC dotnet核心web项目，它构建并托管在一个蔚蓝的web应用程序上。在解决方案中，我有一个xUnitTest项目。

我可以在解决方案中成功地构建两个项目，并在VSTS中为发布阶段发布构建阶段的结果。我可以很好地完成Webapp，但是我想在webapp部署之后运行测试，这就是我遇到问题的地方。

​

试图通过powershell运行"dotnet测试“失败，说它找不到VisualStudio2017项目没有的project.json。

当我使用'dotnet‘发布步骤时，它告诉我csproj不存在，我可以从powershell中看到它确实存在。

我可以使用完全相同的命令在我的本地命令行上成功地运行"dotnet测试“，但是我需要在VSTS上运行，这样我就可以将测试部分作为CI构建的一部分。

检查：

1. 您使用托管的VS 2017队列，而不是默认的托管队列或安装了1.0.0+ CLI的自定义计算机。
2. 确保在您的项目(或在global.json上)中没有使用1.0.0-preview2-*版本的CLI文件--这可能是您看到project.json does not exist消息的原因。
