How to launch FsUnit tests on Linux/Mac - f#

Question

I have installed FsUnit
» nuget install fsunit
Attempting to resolve dependency 'NUnit (≥ 2.6.3)'.
Installing 'NUnit 2.6.3'.
Successfully installed 'NUnit 2.6.3'.
Installing 'FsUnit 1.3.0.1'.
Successfully installed 'FsUnit 1.3.0.1'.
I have created simple unit test:
module Tests
open NUnit.Framework
open FsUnit
[<Test>]
let ``simple test`` () =
1 |> should equal 1
Here is I am launching my test:
» fsharpc -r NUnit.2.6.3/lib/nunit.framework.dll -r FsUnit.1.3.0.1/Lib/Net40/FsUnit.NUnit.dll 01_binomial_tests.fs

/Users/demas/development/book_exericses/fsharp_deep_dive/01_binomial_tests.fs(7,1): warning FS0988: Main module of program is empty: nothing will happen when it is run
It was compiled fine but I don't know how to launch the tests without VS
Update
I have tried to use NUnit.Runners:
> nuget install NUnit.Runners
> fsharpc -r NUnit.2.6.3/lib/nunit.framework.dll -r FsUnit.1.3.0.1/Lib/Net40/FsUnit.NUnit.dll --target:library 01_binomial_tests.fs
> mono NUnit.Runners.2.6.4/tools/nunit-console.exe 01_binomial_tests.dll

Answer 1

You have a couple of options:
Add dependency on NUnit.Runners NuGet package, which comes with a stand-alone runner
Use Xamarin Studio, which seems to have Unit Tests panel for running tests
Use FAKE which is a nice F# build tool that can run unit tests
I personally use FAKE because it nicely automates everything. To do that, you need to put something like this in your FAKE build.fsx script:
Target "Test" (fun _ ->
!! "/tests*.dll |> NUnit (fun p ->
{p with
DisableShadowCopy = true;
OutputFile = testDir + "TestResults.xml" })
)
You'll need dependencies on FAKE and NUnit.Runners and then FAKE should also find the runner automatically (so you do not have to set it explicitly in your build script).
