该项目是一个新项目，只有两个基本的 NUnit 测试。不知道为什么我会收到此错误。我已经阅读了有关此的其他线程，但似乎无法找到解决方案。感谢您的帮助，谢谢！
【问题讨论】：
-
你能发布你的 NUnit 测试的代码吗？你安装了哪些 NuGet 包？
-
StackOverflow 说我在尝试粘贴代码时超出了最大字符数。至于包，我安装了 NUnit 和 NUnit3TestAdapter。以及一些 Selenium 包。
-
发布minimal-reproducible-example。不是完整的代码。它可以帮助您确定根本原因。
-
更多信息可能会有所帮助，但作为一种快捷方式，您可以告诉我们您的代码所针对的运行时。如果是 .NET Core，则无法使用 NUnit 控制台运行程序。
-
堆栈跟踪没有为您的代码显示任何内容。都是框架类。您是否将该项目创建为 NUnit 测试项目？你安装了哪些 NuGet 包？
