Dynamically create tests in NUnit

Question

Using Nunit, I want to be able to write a test fixture that will read all the filenames in a particular directory and create a test for each file.

I could quite easily write one test method that scans through the directory and just does all the tests, but when I run NUnit I want to be able to see each of the tests individually.

Is this even possible?

Answer 1

I've found a way that fits my purposes

Have one test case, and mark it with the TestCaseSource attribute like so

[Test, TestCaseSource("GetTestCases")] public void TestFile(string filename) {     //do test } 

Then write the GetTestCases to read all the file names in the directory

private static string[] GetTestCases() {     return GetAllFilesInCurrentDirectory(); } 

Then when I start NUnit I get a list of the tests to be run (listed under TestFile).
