For me, I'm good with leaving it untested since it's really only used for testing itself and I'm not interested in falling into "testing recursion". finalkut: I suppose you could continue to pull pieces out (Assembly, Stream) until you get the thinnest layer possible but at some point you’d simply have to have an integration test that gets you that “last mile”.

I have a very similar method - though it is static - in a standard library - and I have pretty good test coverage on everything except for the extraction of an embedded resource. Because the method I'm testing is more utilitarian than just for unit testing it expects the embedded resource to be in the "entry assembly" so I use Assembly.GetEntryAssembly().GetManifestResourceStream(resource); However, with a unit test there is no "EntryAssembly" Any thoughts?

Any thoughts?

Some of them are fat, and we started having problems with memory usage inside Visual Studio with R#, so we now have a separate statically referenced assembly with all our test resources in it.

I am surprised at the flexibility and versatility of the language.

I often have the situation that I need to access a file on disk for my code. So I wrote an IDisposable wrapper that uses Embedded Resources just as you describe. Details can be found here: http://www.timrayburn.net/2006/02/19/ExternalFileDependencyInNUnit.aspx Good content! Keep it coming! Tim Dave,
