(#kxlpuda) @lyse@lyse.isobeef.org Oh btw… The reason a io.Writer is left out for “stderr” is that normally I tend to just set the logging output to os.Stderr, like log.SetOutput(os.Stderr) anyway and its not usually something I end up testing. Not sure if this is the best approach, but I’m only really interested in testing the “output”(s) and either error or non-error cases.
