A modern programming language that makes developers happier.

kotlinlang

there are tests that sometimes very rarely fail and it stays a mystery why they do. i wonder if it makes sense to have support for outputting more diagnostic output in that case

```                expectThat(totalEvents).containsExactly(
                    listOf("first test", "second close callback", "first close callback"),
                    listOf("second test", "second close callback", "first close callback"),
                ).onFailure {.... } ```


thats one assertion from my testing library that fails every month or so.

and when it fails i get some ideas of values i could output in that case.

for example if its threading related it could be interesting if 100ms later the values finally is as expected
