How to setup AutoFixture.NUnit2

With the release of AutoFixture.NUnit2 earlier today, here is some guidance how to get it working

NUnit Documentation: Addin Identification, Loading and Installation

NUnit examines all assemblies in the bin/addins directory, looking for public classes with the NUnitAddinAttribute and implementing the IAddin interface. It loads all those it finds as Addins

After package install you need to copy packages\AutoFixture.NUnit2.3.9.0\lib\net40\Ploeh.AutoFixture.NUnit2.Addins.dll to bin\addins folder

But where exactly is bin/addins located. The short answer is where is the nunit.exe or nunit-console.exe located

Here is some default locations

  • NUnit2.6.2 -> C:\Program Files (x86)\NUnit 2.6.2\bin\addins
  • R# 8 -> C:\Program Files (x86)\JetBrains\ReSharper\v8.0\Bin\addins
  • TestDriven.Net -> C:\Program Files (x86)\TestDriven.NET 3\NUnit\2.6\addins

Mark Seemann better explains how to use AutoDataAttribute here:

NUnit example

[Test, AutoData]
public void IntroductoryTest(
    int expectedNumber, MyClass sut)
    int result = sut.Echo(expectedNumber);
    Assert.Equal(expectedNumber, result);


About me? I have been programming since I can remember if it wasn’t the video recorder for my mum, then it was whatever electronic device I can get my hands on.
