When writing tests that depend heavily on resources and attachment files, it is usually convenient to have an easy way to retrieve the resources, and also to have a way to organize the attached files based on the test IDs.

NUnit provides the properties needed to build per test paths in the TestContext object, but the rest is up to the developer.

This library provides a last mile API, easing the process of working with resources and file attachments.


The library defines two attributes

  • ResourcePathFormat(string format)
  • AttachmentPathFormat(string format)

Which can be used in assemblies, classes and individual methods.

The format defines how the test output directory will be created for the given test, by using a number of macros:

Predefined absolute path macross:

macro value
WorkDirectory or * context.WorkDirectory
TestDirectory context.TestDirectory
TempDirectory System.IO.Path.GetTempPath()
CurrentDirectory Environment.CurrentDirectory
SolutionDirectory finds the top most solution (.sln) file and takes its directory

predefined relative path macross:

macro value
ID or ? context.Test.ID
Name context.Test.Name
FullName context.Test.FullName
ClassName context.Test.ClassName
MethodName context.Test.MethodName
CurrentRepeatCount context.CurrentRepeatCount
WorkerId context.WorkerId
Date DateTime.Now 'yyyMMdd'
Time DateTime.Now 'hhmmss'

By using these macros, we can define the attribute like this:


when running a test, it will replace the macros with the appropiate values taken from the current test context.

the default and most common use will be


which creates a directory for every test.


using NUnit.Framework;

[assembly: ResourcePathFormat("{TestDirectory}/Resources")]
[assembly: AttachmentPathFormat("{WorkDirectory}/TestResults/{ID}")]

namespace TestNamespace
    [AttachmentPathFormat("{WorkDirectory}/{ID}")] // Alternatively: [AttachmentPathFormat("?")]
    public class TestClass
        public void WriteTextAttachment()        
            var text = ResourceInfo

                text += " - good bye!";


        public void WriteExplicitTextAttachment()
            var text = ResourceInfo

            text += " - good bye!";
