NUnit DeploymentItem

Question

In MsTest if I need some file from another project for my test, I can specify DeploymentItem attribute. Is there anything similar in NUnit?

You should check out another thread that contrasts the capabilities of NUnit and MSTest.

The accepted answer here is misleading. NUnit does not offer the [DeploymentItem("")] attribute at all which is what @Idsa wanted an equivalent solution for in NUnit.

My guess is that this kind of attribute would violate the scope of NUnit as a "unit" testing framework as requiring an item to be copied to the output before running a test implies it has a dependency on this resource being available.

I'm using a custom attribute to copy over a localdb instance for running "unit" tests against some sizeable test data that I'd rather not generate with code everytime.

Now using the attribute [DeploymentItem("some/project/file")] will copy this resource from file system into the bin again effectively refreshing my source data per test method:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class | AttributeTargets.Struct,      AllowMultiple = false,      Inherited = false)] public class DeploymentItem : System.Attribute {     private readonly string _itemPath;     private readonly string _filePath;     private readonly string _binFolderPath;     private readonly string _itemPathInBin;     private readonly DirectoryInfo _environmentDir;     private readonly Uri _itemPathUri;     private readonly Uri _itemPathInBinUri;      public DeploymentItem(string fileProjectRelativePath) {         _filePath = fileProjectRelativePath.Replace("/", @"\");          _environmentDir = new DirectoryInfo(Environment.CurrentDirectory);         _itemPathUri = new Uri(Path.Combine(_environmentDir.Parent.Parent.FullName             , _filePath));          _itemPath = _itemPathUri.LocalPath;         _binFolderPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);          _itemPathInBinUri = new Uri(Path.Combine(_binFolderPath, _filePath));         _itemPathInBin = _itemPathInBinUri.LocalPath;          if (File.Exists(_itemPathInBin)) {             File.Delete(_itemPathInBin);         }          if (File.Exists(_itemPath)) {             File.Copy(_itemPath, _itemPathInBin);         }     } } 

Then we can use like so:

[Test] [DeploymentItem("Data/localdb.mdf")] public void Test_ReturnsTrue()  {     Assert.IsTrue(true); }
