Come on. I added a simple test program. If someone told me to write unit
tests for it, I would have done it. But there has just been
no reaction for 10 months.
Do the twisted developers only start fixing bugs if the bug reporter
writes a unit test revealing that bug?

I'm not trolling. Reporting bugs is also a form of contribution, people
spent time on doing it, even sent a patch, and get ignored.
[http://twistedmatrix.com/bugs/issue392]. And you start insulting them
(btw. what is peanut gallery?), instead of being glad that they
give back their feedback?

My experience was fine. We were already using the patched version. But,
to repeat myself:
I would have written unit tests if someone told me to do it.

I look at the speed of fixing bugs. And in this particular case it took
18 months or so to fix it.
I have added other bug reports, without getting any reaction.
IMHO, having working code without tests is better than having buggy code
without tests (well, one might argue that it's the same...).

I admit that it's nice for the twisted developers to have bug reports in
the form of failing unit tests. But you can't expect everyone
to write them.

I'm not whining (actually I write unit tests at work). We use twisted at
our company and appreciate the work that has gone into it.
But one thinks about saving that work of reporting bugs, when they just
aren't dealt with.
