Re: I don't get it. version(unittest) can't seem to use local variable

[dysmondad via Digitalmars-d-learn]

.....

try:

unittest {
      Velocity v = new Velocity( 2.0f, 5.0f );
      v *= 5.0f;  // <- line 110
      printf( "v = %s\n", to!string(v) );
}

instead. Basically version is like static if, it doesn't 
indicate its a function. Instead it changes what code gets 
compiled.
Where as a unittest block, is essentially just a function that 
gets called at a special time, that is only compiled as if 
version(unittest) was also used.

Thank you very much. That was quite helpful.

So, what is the generally accepted way include unit testing? TDD 
is all the rage these days and I though I would try my hand at it 
as well as D.
