That's exactly what you mustn't do. Ideally the test is written from the 
functional specs - which I can get close to because I tend to write the 
description, which corresponds to the module/class level comment and the 
associated function/method descriptions and prototypes/method signatures 
along with any externally visible constants, IOW a module spec before any 
code. However, I do write these as a set of comments with skeletal code 
interspersed so they should compile correctly. I find this helps me get 
the interfaces right and assists with splitting the code up into sensible 
functions/methods. 

Once this has been done, its the right time & place to write the test 
scripts so they end up being written to the the spec rather than to the 
code. Its also a good time to set up the interface code module for the 
test harness. Since this is just an if..then..else totem pole containing 
essentially no other logic, this is as good a time as any to write it. 
All the tests, testing logic and corner cases can be set up and tested in 
the test scripts. These are entirely linear: conditions aren't needed 
because any possible set of inputs and call sequences can be expressed in 
a linear script.

I find using a debugger is a lot slower that using diagnostic tracing but 
obviously we differ there. Besides, I like leaving the diagnostics in the 
finished code and always under the control of a debug option because this 
the overheads are minimal and troubleshooting problems, often the result 
of the code being used in ways that nobody thought of, that can occur 
later is much easier.

Likewise, I'm in the midst of a configurable 8/16 bit emulator for 68xx, 
63xx and 65xx series chips. This is a C program because the lack of 
unsigned numeric variables made hardware register emulation very nasty i 
Java, bit I digress. Currently there are between 50 and 60 test scripts 
used to exercise its various modules. A complete regression test, which 
uses the complete set of test scripts, currently runs in 1.3 seconds,

Quite. I use make for C and ant for Java, CVS gets used for both  and, 
errm, not a lot more apart from my C and Java test harness. However I 
have used Flex+bison (lex+yacc if you prefer) and curses with C and Coco/
R with Java. I now have one toe in the git water and may well move 
entirely to it. Similarly, I'd now use Coco/R for C rather than flex
+bison.

Same here, though in my case its the PostgreSQL JDBC driver.
