use of tests in developing log4j?

["Braithwaite, Keith" <kb...@zuhlke.com>]

Greetings all,

I'm conducting some research into TDD and its effect on design. Through
looking at various open-source Java codebases I've found what looks like
a positive correlation between a certain design metric and the use of
test-driven design. This isn't (and isn't meant to be) a figure of merit
in its own right, but if the correlation does hold then it could be an
interesting parameter for teams that do choose to use TDD.

 

I've looked at log4j 1.2.15 and found the metric on the high (ie "TDD")
side. 

 

Could you spare a couple of minutes to explain briefly how your use
tests in the development of log4j? I'm mainly interested how you drive
out design decisions and if that policy has become different over
time-which perhaps might show up differently in different parts of the
code.

 

Best Regards,

Keith
