@ramblurr No, there's no. It's kind of hard to decide where exactly a new test should go within a test ns, but if you have concrete ideas feel free to open a feature request ticket.


It will create the missing file given the universal prefix (C-u).


Hello everyone, I recently started getting this error when ever I get a runtime error. Does anyone know what may be going on? PS: the error buffer appears rarely now, and I get most errors directly on the repl buffer. PS2: seems like it may be a problem with a single specific repository, but it’s the one I have been mainly working on, so it’s hard tell with 100% certainty. But if it was the case, we are using mulog and that seems to interact with logging in some ways.

known one - you're using Orchard 0.9.0 and latest is 0.9.2


so use that latest cider and/or cider-nrepl stable stack and it will be gone :)


Hi @U7AMPCPU2 I'm the author of μ/log and I use cider as well for my development and I never seen this error. I agree with @U45T93RA6, by the message it looks like a version mismatch between cider and cider-nrepl. however should the error persist, I'll be happy to help you to debug and check whether mulog is the cause of to rule it out.


Thanks a lot @U45T93RA6 and @U0LCHMJTA. Appreciate your help. I’ll update ASAP and will let you know if the issue persists.


All working good now with the orchard update
