I have a should-not-compile test that fails (the code in question supposedly compiles); however if I take that exact code and paste it next to the test case, the whole thing fails to compile. No idea how to troubleshoot this.
(Screenshot 1: the test fails because the code compiles. Screenshot 2: the same code fails to actually compile.)

12/02/2025, 11:33 AMThis looks like a Kotlin bug, the IDE itself doesn't recognize it's non-compilable

12/02/2025, 11:34 AMright, but in the actual compiler it fails; does kotest not run the same compiler my project compiles with?

12/02/2025, 11:34 AMintellij being spotty with type inference detection is not uncommon

12/02/2025, 11:36 AMI'm not sure.
If we're using the same compiler as IntelliJ, they'll fail together. If we use the same as Kotlin it should fail.
IIRC we use KotlinPoet, which probably uses compiler plugins which probably comes close to what IntelliJ does. Let me check on this details
Anyways, I don't think this is an easy fix

12/02/2025, 11:40 AMok, i'll upstream the issue then
Jakob Heher
12/02/2025, 11:40 AMhm, seems like that library is unmaintained, they have an open issue (with no maintainer activity) from july 2024 about supporting kotlin 2
Jakob Heher
12/02/2025, 11:40 AMso i assume that means that currently kotest compile tests compile using an old K1 compiler
Jakob Heher
12/02/2025, 11:41 AMwhich probably explains why the type inference is different

12/02/2025, 11:41 AMHmm.. With that in mind we'll probably have to replace the library we are using
LeoColman
12/02/2025, 11:41 AMWould you mind creating a ticket to track this? Now it's definitely a bug on our side xD

sam
12/03/2025, 2:42 AMso we should just be able to bump to that
