I’m probably being thick, but I’m finding that I don’t get nice coroutine stacktraces in IntelliJ when my test fails in an 
eventually
block. VM options: 
-ea -Dkotlinx.coroutines.debug=on -Dkotlinx.coroutines.stacktrace.recovery=true
(belt, braces, stapled on to stomach).
Yet the stack is still useless - only references the one line in my code where the assertion actually failed.
s
is the stack just full of kotlin references rather than your own code ?
r
Yup
I can stick it up here if you’re feeling masochistic.
s
sure

Copy code

s
ebay sniper?
so its because eventually is keeping the first and last errors, and just showing the messages
so it's just a limitation of the way we've coded it
can you make an issue on github, we can change that to print the entire stack
r
Sure, will do
(It’s the main exercise from Growing Object Oriented Software Guided by Tests)
s
ah nice
is it a kotest thing
or a generic test thing
r
The book? It’s from 2009.
s
oh lol
that's a few haircuts ago
r
Yup, having to transpose it into kotlin / mockk / gradle / kotest ensures that I’ve really understood what they are trying to teach.
s
nice, good idea
fun little project
then you can start doing tickets on kotest 😛
r
I probably owe you one or two!
s
well next time you're in chicago you can buy me one
or next time I'm in the uk
r
Sure. If we ever get to travel again.
s
ha, in 2032
