Using xunit or nunit as test runner framework

Question

I'll start with an problem. I have a little library. It goes through a list of urls in text files and create assertions depending on the url returns 200 or not.

The goal is to make a test runner like Reshaprer, Testdriven.net or a CI server like team city or hudson to pick up the assertions as tests.

My question is how do I extend/build upon xunit or nunit to run tests from another source? Examples would be great.

Update To make things a bit more clear. I should be able to look load the dll in the test runner that ships with xunit/nunit and run the test.

How the list of urls is populated is very dynamic. Depending on certain things more url can be created. So a list of data is not an option.

If you mean how can you run NUnit tests programmatically (instead of using one of the supplied NUnit runners), then it's actually pretty easy:

using System; using NUnit.Core; using NUnit.Framework; using MyProject.Tests; /* assuming MyTestFixture is defined in this project/assembly */ namespace TestRunner.DemoApp { class Program { static void Main(string[] args) { var builder = new TestSuiteBuilder(); var testAssemblyLocation = typeof(MyTestFixture).Assembly.Location; var package = new TestPackage(testAssemblyLocation); var suite = builder.Build(package); Console.ForegroundColor = ConsoleColor.White; Console.WriteLine("Running tests from " + testAssemblyLocation; Console.WriteLine("Testing against " + ConfigurationManager.AppSettings["HostNameSuffix"]); var result = suite.Run(new NullListener(), TestFilter.Empty); switch (result.ResultState) { case ResultState.Success: Console.ForegroundColor = ConsoleColor.Green; Console.WriteLine("Pass."); break; case ResultState.Error: case ResultState.Failure: Console.ForegroundColor = ConsoleColor.Red; DrawResults(result.Results, r => r.ResultState == ResultState.Error || r.ResultState == ResultState.Failure); break; } static void DrawResults(IList results, Func<TestResult, bool> include) { foreach (var obj in results) { var result = obj as TestResult; if (result == null) continue; if (result.Results != null && result.Results.Count > 0) { DrawResults(result.Results, include); } else if (include(result)) { Console.WriteLine(result.Name); Console.WriteLine(result.Message); Console.WriteLine(result.ResultState); Console.WriteLine(result.StackTrace); Console.WriteLine(String.Empty.PadLeft(Console.WindowWidth, '=')); } } } } }

Not really what I was looking for. I don't need to build a test runner. I need to run test in nunits test runner.

With xUnit, all you need is to implement ITestRunner interface, i.e.:

public class MyTestRunner : ITestRunner { // Methods public MyTestRunner(); public static TestRunState RunAssembly(TestRunner runner); public static TestRunState RunClass(TestRunner runner, Type type); public static TestRunState RunClassWithInnerTypes(TestRunner runner, Type type); public static TestRunState RunMethod(TestRunner runner, MethodInfo method); TestRunState ITestRunner.RunAssembly(ITestListener listener, Assembly assembly); TestRunState ITestRunner.RunMember(ITestListener listener, Assembly assembly, MemberInfo member); TestRunState ITestRunner.RunNamespace(ITestListener listener, Assembly assembly, string ns); }

For implementation details, grab the source code of xUnit and have a look at the sample runners.

You can use the TestCaseSourceAttribute in NUnit to run dynamic tests.
