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.

is the stack just full of kotlin references rather than your own code ?

Rob Elliot

10/16/2020, 5:13 PM

Yup

I can stick it up here if you’re feeling masochistic.

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

Rob Elliot

10/16/2020, 5:16 PM

Sure, will do

(It’s the main exercise from Growing Object Oriented Software Guided by Tests)

sam

10/16/2020, 5:16 PM

ah nice

is it a kotest thing

or a generic test thing

Rob Elliot

10/16/2020, 5:18 PM

The book? It’s from 2009.

sam

10/16/2020, 5:18 PM

oh lol

that's a few haircuts ago

Rob Elliot

10/16/2020, 5:23 PM

Yup, having to transpose it into kotlin / mockk / gradle / kotest ensures that I’ve really understood what they are trying to teach.

sam

10/16/2020, 5:23 PM

nice, good idea

fun little project

then you can start doing tickets on kotest 😛

Rob Elliot

10/16/2020, 5:28 PM

I probably owe you one or two!

sam

10/16/2020, 5:28 PM

well next time you're in chicago you can buy me one

or next time I'm in the uk

Rob Elliot

10/16/2020, 5:30 PM

Sure. If we ever get to travel again.

sam

10/16/2020, 5:31 PM

ha, in 2032
