Yes, thus for Bill this mean that for amount of time already expended you need about the same amount for writing tests.  YMMV if the cyclomatic complexity (or similar metric) is higher of lower than 'average' programs.

In a more commercial scenario, you can cite Gartner's Research Note SPA-19-3568 where they put 10 to 15% of total development time for unit testing and 10 to 15% time for system [integration] testing.

These numbers vary a lot, but you can find good references in Software Engineering books or periodicals.

Robert Martin said in his book that one should spend ~50% of its time writing tests.
