Run NUnit test on Ubuntu from command line

Question

How to run NUnit test on Ubuntu from the command line?

I've created file OnlyTest.cs

using System;
using System.Text;
using System.Collections.Generic;
using NUnit.Framework;

[TestFixture]
public class OnlyTest
{
    [Test]
    public void MyTest() 
    {
        int a = 10;
        Assert.AreEqual(10, a);
    }
}

According to article Running NuGet command-line on Linux I've downloaded files NuGet.exe and Microsoft.Build.dll

I've run NuGet to install NUnit

$ mono NuGet.exe install NUnit
    Installing 'NUnit 2.6.4'.
    Successfully installed 'NUnit 2.6.4'.

    $ ls -lR
    .:
    razem 1668
    -rw-rw-r-- 1 mw mw   28861 cze 24 23:45 Microsoft.Build.zip
    -rw-rw-r-- 1 mw mw 1664512 cze 24 23:42 NuGet.exe
    drwxrwxr-x 3 mw mw    4096 cze 25 00:29 NUnit.2.6.4
    -rw-rw-r-- 1 mw mw     208 cze 25 00:27 OnlyTest.cs

    ./NUnit.2.6.4:
    razem 108
    drwxrwxr-x 2 mw mw  4096 cze 25 00:29 lib
    -rw-rw-r-- 1 mw mw  1131 cze 25 00:29 license.txt
    -rw-rw-r-- 1 mw mw 99004 cze 25 00:29 NUnit.2.6.4.nupkg

    ./NUnit.2.6.4/lib:
    razem 720
    -rw-rw-r-- 1 mw mw 151552 cze 25 00:29 nunit.framework.dll
    -rw-rw-r-- 1 mw mw 584600 cze 25 00:29 nunit.framework.xml

Since I'm not sure about compiling and running

Compiling hadn't produce any errors

mcs OnlyTest.cs -target:library -r:NUnit.2.6.4/lib/nunit.framework.dll -out:OnlyTest.dll

But when I try run nunit I get errors like

$ nunit-console OnlyTest.dll -noresult

The same goes for nunit-gui

Could not load file or assembly 'nunit.framework, Version=2.6.4.14350, Culture=neutral, PublicKeyToken=96d09a1eb7f44a77'

Check which nunit-console/nunit assemblies that are installed... I assuming it is picking up old assemblies in the GAC.

Lets start from the beginning:

Get the latest and greatest NUnit AND it's Runner tools

curl https://api.nuget.org/downloads/nuget.exe -o nuget.exe
mono nuget.exe install NUnit
mono nuget.exe install NUnit.Runners

Make sure the mono is finding those assemblies first (vs the GAC)

export MONO_PATH=$(PWD)/NUnit.Runners.2.6.4/tools:$(PWD)/NUnit.2.6.4/lib

Create your test example and compile it:

vi OnlyTest.cs #Using the example in your question
mcs OnlyTest.cs -target:library -r:NUnit.2.6.4/lib/nunit.framework.dll -out:OnlyTest.dll

Run it:

mono ./NUnit.Runners.2.6.4/tools/nunit-console.exe OnlyTest.dll -noresult

Output:

Answer 2

FYI: I build mono from source as I'm on OS-X and the official disto is still 32-bit.

Getting the the latest and greatest on Ubuntu:

Debian, Ubuntu, and derivatives Add the Mono Project GPG signing key and the package repository to your system (if you don't use sudo, be sure to switch to root):

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
sudo apt-get update

Run a package upgrade to upgrade existing packages to the latest available. Then install Mono as described in the Usage section.

Note: While the APT package is built against Debian Wheezy, it is compatible with a number of Debian derivatives (including Ubuntu) which means you can use the same repository across all these distributions.
