I observe a dramatic typing lag increase and general IDE unresponsiveness when editing a certain koTest file. It contains a ShouldSpec and is about 1000 lines long (oh, actually exactly 1000, heh). I recall that several years ago there was a similar issue with the

Spec

test framework and it was related to the fact that there is a big lambda, wrapping everything here:

class MyTest : ShouldSpec(<big_lambda>)

I'm here to ask if anyone can provide me with the YouTrack link or something which I could track and report further findings — I suspect this is a known issue. P.S. In Spec-days it seemed to get improved, but maybe not enough...

Is the typing-lag still there if you disable the Kotest plugin?

I guess I'l have to also restart? Actually it maybe not exactly typing lag, although it does happen often, but certainly a) syntax highlight lag — after I copy-paste something, code/errors get highlighted after about 5 seconds which is ridiculous b) I constantly see "Resolving pasted code imports" in the status line, which normally happens instantly.

I think so. I'm asking because I remember seeing such a report but where JB said that the Kotest plugin was the culprit.

I recall one related issue that was primarily caused by passing the test lambda directly to the constructor. Using an

init

block instead resolved the issue, maybe it'll help for you too?

Yep, Spek (I mistyped) is here.

Using an

init

block instead

Oh right! I recall this was earlier solution too. I'll try it!

Wow, switching to

init

made a huge difference, thanks! Our 3kLOC spec is actually editable now.

I wish these issues wouldn't exist at all in our modern age with modern hardware 🥲 3kLOC really should be nothing to my beast of processor 🙂
