question @sam a co-worker of mine just ran into a problem like below

test("should print out failing inputs and shrinks when a function throws") {
      suspend fun functionThatUnexpectedlyThrows() { throw RuntimeException("aaaa") }
      checkAll(Arb.bigInt(4, 4)) { value ->
         functionThatUnexpectedlyThrows()
      }
   }

and then I realized that we don’t report the inputs or attempt any shrinking to the users when the exception is not kotest’s assertion errs. i.e.

Property failed after 1 attempts
java.lang.AssertionError: Property failed after 1 attempts

Repeat this test by using seed 320358835705021305

Caused by RuntimeException: aaaa

if that function was wrapped around shouldNotThrowAny { .. } then that’ll print out the inputs and properly shrunk it.

it’s written here

is this by design? or should we fix that?

if you reckon that’s a bug i can raise an issue and raise a fix PR?
