Question

我正在尝试使用单声道在linux中设置一个非常简单的测试F＃项目，使用Forge来设置项目并安装nuget包。 Forge创建一个使用FAKE的build.fsx文件。我已尝试使用本教程http://fsharp.github.io/FAKE/gettingstarted.html的灵感来调整此构建文件（为了添加测试）。但是，本教程使用C＃进行测试，并假定使用.Net作为环境的Windows。我想用F＃进行测试，用linux作为环境。

我想我差点搞定了，但是我从NUnit那里得到了一些神秘的错误信息。运行build.fsx文件时，我最终会收到以下错误：

...
Invalid argument: -nologo
The value '/home/michel/Documents/FSHARP/UnitTests/test/NUnit.Test.MyTests.dll' is not valid for option '--labels'.
Invalid argument: -xml:./test/TestResults.xml
Running build failed.
Error:
NUnit test failed (255).

我的build.fsx文件看起来像这样

// include Fake libs
#r "./packages/FAKE/tools/FakeLib.dll"

open Fake


// Directories
let buildDir  = "./build/"
let testDir = "./test/"

// version info
let version = "0.1"  // or retrieve from CI server

// Targets
Target "Clean" (fun _ ->
    CleanDirs [buildDir; testDir]
)

Target "Build" (fun _ ->
    //MSBuildDebug buildDir "Build" appReferences
    !! "/UnitTesting/*.fsproj"
    |> MSBuildRelease buildDir "Build"
    |> Log "AppBuild-Output: "
)

Target "BuildTest" (fun _ ->
                    !! "src/NUnit.Test.MyTests/*.fsproj"
                    |> MSBuildDebug testDir "Build"
                    |> Log "TestBuild-Output: "
)

Target "Test" (fun _ ->
               !! (testDir + "/NUnit.Test.MyTests.dll")
               |> NUnit (fun p ->
                         { p with
                               ToolPath = "packages/NUnit.ConsoleRunner/tools"
                               //DisableShadowCopy = true;
                               OutputFile = testDir + "TestResults.xml" })
)

Target "Default" (fun _ -> trace "HEEEELLOOOOOO world from FAKE!!!")

"Clean" ==> "Build" ==> "BuildTest" ==> "Test" ==> "Default"

RunTargetOrDefault "Default"

FAKE似乎在nunit-console.exe目录下寻找文件packages/NUnit.ConsoleRunner/tools，但没有这样的文件。但是，有一个nunit3-console.exe文件，因此我只使用名称nunit-console.exe制作了此文件的副本。

我的简单测试文件NUnit.Test.MyTests.fs如下所示：

namespace NUnit.Test.MyTests

module testmodule =

    open NUnit.Framework

    let SayHello name = "Hello"

    [<TestFixture>]
    type myFixture() =

        [<Test>]
        member self.myTest() =
            Assert.AreEqual("Hello World!", SayHello "World")

并且文件test/NUnit.Test.MyTests.dll似乎生成得很好。

隐秘的错误消息是什么意思，我该如何修复它以便我可以运行我的测试？

正如评论中的rmunn所提到的，我需要使用函数NUnit3，因为我使用的是NUnit版本3.4.1。该函数位于FAKE.Testing模块http://fsharp.github.io/FAKE/apidocs/fake-testing-nunit3.html中。我修改了我的build.fsx文件，现在看起来如下：

// include Fake libs
#r "./packages/FAKE/tools/FakeLib.dll"

open Fake
open Fake.Testing // NUnit3 is in here


// Directories
let buildDir  = "./build/"
let testDir = "./test/"

// version info
let version = "0.1"  // or retrieve from CI server
// Targets
Target "Clean" (fun _ ->
    CleanDirs [buildDir; testDir]
)

Target "Build" (fun _ ->
    !! "/UnitTesting/*.fsproj"
    |> MSBuildRelease buildDir "Build"
    |> Log "AppBuild-Output: "
)

Target "BuildTest" (fun _ ->
                    !! "src/NUnit.Test.MyTests/*.fsproj"
                    |> MSBuildDebug testDir "Build"
                    |> Log "TestBuild-Output: "
)

Target "Test" (fun _ ->
               !! (testDir + "/NUnit.Test.*.dll")
               |> NUnit3 (fun p ->
                         { p with
                               ToolPath = "packages/NUnit.ConsoleRunner/tools/nunit3-console.exe" })
)


Target "Default" (fun _ -> trace "HEEEELLOOOOOO world from FAKE!!!")

"Clean" ==> "Build" ==> "BuildTest" ==> "Test" ==> "Default"

RunTargetOrDefault "Default"

请注意，您必须一直指定ToolPath nunit3-console.exe文件，而不仅仅指定它所在的目录。

现在一切似乎都有效，我得到了一个简单的测试摘要＆＃39;在我运行build.fsx时在控制台输出中。：）
