How to get Directory while running unit test

Question

Hi when running my unit test I\'m wanting to get the directory my project is running in to retrieve a file.

Say I have a Test project named MyProject. Test I run:

<

Answer 1

For NUnit this is what I do:

// Get the executing directory of the tests 
string dir = NUnit.Framework.TestContext.CurrentContext.TestDirectory;

// Infer the project directory from there...2 levels up (depending on project type - for asp.net omit the latter Parent for a single level up)
dir = System.IO.Directory.GetParent(dir).Parent.FullName;

If required you can from there navigate back down to other directories if required:

dir = Path.Combine(dir, "MySubDir");

Answer 2

I normally do it like that, and then I just add "..\..\" to the path to get up to the directory I want.

So what you could do is this:

var path = AppDomain.CurrentDomain.SetupInformation.ApplicationBase + @"..\..\";

Answer 3

You can do it like this:

using System.IO;

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, @"..\..\"));

Answer 4

I would do it differently.

I suggest making that file part of the solution/project. Then right-click -> Properties -> Copy To Output = Copy Always.

That file will then be copied to whatever your output directory is (e.g. C:\Source\MyProject.Test\bin\Debug).

Edit: Copy To Output = Copy if Newer is the better option

Answer 5

The best solution I found was to put the file as an embedded resource on the test project and get it from my unit test. With this solution I don´t need to care about file paths.

Answer 6

In general you may use this, regardless if running a test or console app or web app:

// returns the absolute path of assembly, file://C:/.../MyAssembly.dll
var codeBase = Assembly.GetExecutingAssembly().CodeBase;    
// returns the absolute path of assembly, i.e: C:\...\MyAssembly.dll
var location = Assembly.GetExecutingAssembly().Location;

If you are running NUnit, then:

// return the absolute path of directory, i.e. C:\...\
var testDirectory = TestContext.CurrentContext.TestDirectory;
