Spurious assertion failure

[finitish]

The Assert in the C# code at the bottom of this post fails, with the following stack trace:

> .\Finity.Tests\bin\Debug\Finity.Tests.exe

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

   at NUnit.Framework.Assert.That(Object actual, IResolveConstraint expression, String message, Object[] args)

   at NUnit.Framework.Assert.That(Boolean condition)

   at Finity.Tests.Program.Main(String[] args) in \\store\pers\vers\finity\Finity.Tests\Program.cs:line 16

#

Uncommenting the 3 commented lines executes a do-nothing test, and the Assert no longer fails:

> .\Finity.Tests\bin\Debug\Finity.Tests.exe

NUnit does not have this problem.

Weird? My environment is 64-bit Windows 7, and nunitlite is added as NuGet package to a default console application project in a default Visual Studio 2012 solution.

#

namespace Finity.Tests
{
  using System;
 
  using NUnit.Framework;
 
  class Program
  {
    //[Test]
    //public void Null() { }
 
    static void Main(string[] args)
    {
      //new NUnitLite.Runner.TextUI().Execute(args);
 
      Assert.That(1 == 1);
    }
  }
}

So you have an assertion outside of any test method and which is not
run under NUnitLite at all. It throws an exception because it's not
running in the proper environment. We could analyze in detail exactly
how it fails, but that does not seem very useful. Just don't try to
Assert outside of your tests!

In the case of NUnit, a Main with an Assert would not cause a problem,
because it would not be executed at all.
