Test is a "Lite" tool that reports the results of software tests. Latest improvement is the addition of helper methods FloatsAreEqualWithinFraction and FloatsAreEqualWithinTolerance to simplify testing floating point results that are not identical.

Benefits

• It's entirely free.

• It's only 195 lines, so it's understandable.

• It's source code, so you can play with it.

• It’s much lighter weight than NUnit or VS2005 Test.

• It’s a batch-like tool, and runs as many tests as possible.

• It doesn’t use Debug.Assert, so a test run doesn't stop to handle exceptions.

• Each method is documented using XML style for viewing in the Object Browser.

Usage

• Add a class to your project that will execute your tests, say,
      Class MyTester{}

• Write your method(s)

• In MyTester, add the code to test your methods by calling a Test instance.

• Execute MyTester

Example

    Assume you're testing Test itself. This code might be typical:

    using EngineeringObjects.Tester;    //    Test namespace

    namespace SomePlace {
    class Program {
        static void Main(string[] args) {

            Test t = new Test( Console.Out );    //    Test instance

            t.AssertTrue( true, "AssertTrue" );
            t.AssertFalse( false, "AssertFalse" );

            double a = 1.0;
            double b = 1.0;
            t.AssertTrue( a == b, "Equal" );
            t.AssertTrue(t.FloatsAreEqualWithinFraction(a,b,0.01),"a within 1% of b");

            b = 2.0;
            t.AssertFalse( a == b, "Unequal" );
            t.WritePassed( "another passed test" );
            t.TheTextWriter.WriteLine( "writing to the TextWriter" );
            t.Report();

            Console.WriteLine( "Press Enter to end..." );
            Console.ReadLine(); //  wait for Enter key
        }
    }
}

Signatures in the Test class

namespace EngineeringObjects.Tester
{
      public class Test
      {
            public Test( TextWriter tw );
            public int TestsFailed {
                  get;
                  set;
            }
            public int TestsPassed {
                  get;
                  set;
            }
            public int TestsTotal {
                  get;
                  set;
            }
            public TextWriter TheTextWriter {
                  get;
            }
            public void AssertFalse( bool isTrue, string message );
            public void AssertTrue( bool isTrue, string message );
            public string Failed( string message );
            public bool FloatsAreEqualWithinFraction( double a, double b, double fraction );
            public bool FloatsAreEqualWithinTolerance( double a, double b, double tolerance );
            public string Passed( string message );
            public void Report();
            public void WriteFailed( string message );
            public void WritePassed( string message );
      }
}
