MSpec “Hello World” Sample

I’ve been working with MSpec lately. It’s a BDD framework for .Net. Here’s a hello world type example that uses Trace Writing to show a little bit about what it does.

using System;
using Machine.Specifications;
using System.Diagnostics;

namespace UnitedIndustrial.DataImportConcerns
{
    [Subject("Sample")]
    public class SampleConcerns
    {
        static string _myString;
        Establish _context = () =>
        {
            _myString = "value from context";
            LocationValueDump("context");
        };

        Because _of = () =>
         {
             _myString = "value from because";
             LocationValueDump("because");
         };

        It _shouldKnow1And1Equals2 = () =>
         {
             (1 + 1).ShouldEqual(2);
             LocationValueDump("_shouldKnow1And1Equals2");
         };

        It _shouldKnowANewStringIsNotNull = () =>
        {
            "hello".ShouldNotBeNull();
            LocationValueDump("_shouldKnowANewStringIsNotNull");
        };

        private static void LocationValueDump(string location)
        {
            Trace.WriteLine(
                String.Format("in {0} _myString is {1}",
                location, _myString));
        }
    }
}
