那些遇到过的问题

使用.NET Core和xUnit同时针对多个框架的单元测试代码

Lui*_*iso 8 .net unit-testing xunit.net .net-core

我对.NET的核心部分图书馆哪些目标net45和netstandard1.6,我想单元测试.我做了,dotnet new -t xunittest并创建了一个新的测试项目,netcoreapp1.0以便它只测试.NET Core代码.

我也尝试将其编译为目标,net45但后来我在测试发现时遇到了一系列错误.我的问题是

有没有办法测试针对两个(可能更晚)框架的代码与单个测试项目,还是我应该针对每个目标进行测试项目？

编辑:这是我project.json和我得到的消息:

虽然我知道我有一个测试(至少到目前为止).

然而,如果我删除net 45引用所有像魅力的工作,这是我的工作project.json:

根据xUnit .NET Core文档,

您可以将两者都作为目标net4xx,netcoreapp只需在project.json文件中将两个框架一起添加即可.当您dotnet test使用多个框架条目运行时,系统将一个接一个地运行所有框架测试.

这并不意味着您可以拥有一个针对不同平台的测试项目引用和测试项目(如.NET 4.5项目和.NET Core项目).但它确实意味着您可以测试针对同一组平台的项目.

例如,我有一个同时针对.NET 4.5.1和.NET Core的类库:

{
  "dependencies": {
    "NETStandard.Library": "1.6.0"
  },

  "frameworks": {
    "netstandard1.6": {},
    "net451":  {} 
  },
  "version": "1.0.0-*"
}

我可以定位net451并netcoreapp1.0在我的测试项目,并引用这个类库:

{
  "buildOptions": {
    "debugType": "portable"
  },
  "dependencies": {
    "xunit": "2.2.0-beta2-build3300",
    "dotnet-test-xunit": "2.2.0-preview2-build1029",
    "NetStandardClassLibrary": {
      "target": "project"
    }
  },
  "frameworks": {
    "net451": {},
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0"
        }
      },
      "imports": [
        "dotnet5.4",
        "portable-net451+win8"
      ]
    }
  },

当dotnet test执行,测试将运行两次(一次为每个平台的目标):

当我尝试在Visual Studio中运行测试时,我收到了与您类似的错误消息.我认为这是一个错误,因为dotnet test在命令行上运行正常.
