If you are not going to be adding files to that directory over time and have a set of filenames to pass in as an input to a generic test, try using the RowTest NUnit extension (part of the std distrib post v2.4.7) - You'd be able to see each test case - input combination individually in the GUI grouped under a single node.

If you are going to be adding files to that directory, I'd write a single NUnit TestCase that loops over a list of files obtained at runtime and calls the generic test method with each filepath. Use a collecting parameter to collect failing test file names - at the end you assert. You wouldn't be able to see each test case individually but you'd have readable simple test code.

Assert.AreEqual(listOfFailedFiles.Length, 0, PrettyPrint(listOfFailedFiles))
