@sam halp have you seen anything like this before?

org.junit.platform.commons.JUnitException: TestEngine with ID 'kotest' failed to execute tests
Caused by: java.lang.IllegalArgumentException: Comparison method violates its general contract!

[mitch]

junit annoyingly also swallowed the stacktrace so i need to figure out how to enable it. it also doesn’t consistently happen.

[sam]

Sounds like a custom comparator

[mitch]

looking

[mitch]

i can’t find any custom comparator in that project.. also trying to check in junit or kotest.

[mitch]

hmm i can’t see anything wrong in kotest either. must be something in that project. i’ll try enabling stack trace and get back to you

[mitch]

Thanks Sam!

[mitch]

@sam i think i found the culprit.. i’ve raised an issue there https://github.com/kotest/kotest/issues/2839

[mitch]

and also raised a PR with the fix

[sam]

cool. Will merge once green. I think later this week I can make a 5.1.1 release with this.

[sam]

maybe a 5.0.4 too

[mitch]

Thanks heaps Sam!
