Question

我正在学习C＃，因此如果不能很精确地描述错误，我深表歉意。

我正在学习Pluralsight课程，在单元测试部分，我意识到单元测试不在我的项目中运行。

它会引发以下错误：

[19/11/2018 22:13:26 Informational] ========== Run test finished: 0 run (0:00:00.0535907) ==========

我在网上找到了其他资源 https://developercommunity.visualstudio.com/content/problem/212059/unable-to-debug-unit-test-visual-studio-enterprise.html

和其他解决方案：首先禁用VPN（我没有），然后在提升的PowerShell提示符下运行“set-mppreference -EnableNetworkProtection 0”，然后重新启动VS。

这种方法最终都无法奏效，我无法运行任何测试。

Answer 1

问题是appxrecipe不在单元测试项目的bin文件夹中。

您可以通过为单元测试项目创建一个应用程序包来创建appxrecipe文件。要创建应用程序包，请右键单击您的单元测试项目>“商店”>“创建应用程序包”。

完成后，appxrecipe文件应位于项目的bin文件夹中，Visual Studio应该能够运行单元测试。

Visual Studio 2017 UnitTest未运行
