But okay, > that's a different story. I beg to differ: If code is not testable, it is not good and needs to be changed. If you fear to change it because it is complex and has weird dependencies, you have two choices: - make it testable and the world will be a better place - leave the design as is, actually make it worse by adding workarounds that do not really fit in the old design. If you shied away from changing the design, the next change to the code will be even more daunting. And there will be a next change. There always is. You probably say now: "I know, but ...". If you do, take a step back and meditate about if there can be any "but" that will be valid against the fundamental truth that we need unit tests for the messy code we have and we even more need unit tests for the messier code we have. There isnt. So "Just Do It!" is exactly the right thing to do, even if -- and maybe because -- it not a comfortable road to take. "We choose to write unit tests, not only because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too." -- paraphrasing JFK at Rice ;) Best Regards, Bjoern --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@openoffice.org For additional commands, e-mail: dev-h...@openoffice.org
