Then the compiler need as well to collect all possible asserts and then 
somehow present them to the user. My library implementation already does 
this. Since this is completely implemented in library code it would be 
possible to have different formatters, a basic for outputting to the 
console and a more advanced with HTML output.

Less important but can be quite useful sometimes is that with my 
framework you add contexts to the unit tests, just like RSpec for those 
familiar with it.

If you haven't already, I suggest you take a look at the documentation 
for the unit test framework:

http://dl.dropbox.com/u/18386187/orange_docs/orange.test.UnitTester.html



For example:

import orange.test.UnitTester;

int sum (int x, int y)
{
     return x * y;
}

unittest ()
{
     describe("sum") in {
          it("should return the sum of the two given arguments") in {
               assert(sum(1, 2) == 3);
          }
     }
}

void main ()
{
     run;
}

If a test fails the framework will print out the context, the stack 
trace and a snippet from the failing test, something like this:

  sum
    - should return the sum of the given arguments

  Failures:
      1) sum should return the sum of the given arguments
         # main.d:44
         Stack trace:
         tango.core.Exception.AssertException at main(44): Assertion failure


  describe("sum") in {
  	it("should return the sum of the given arguments") in {
  		assert(sum(1, 2) == 3);
  	};
  };

  1 test, 1 failure
