Sorry for bothering... The test in ShrinkingTest fails for me. (I'm getting one line with the original cause, but no shrinking-steps.) My question is: is this a know bug? The reason I'm asking is that I couldn't find an issue about shrinking not working.

Which test

the test in ShrinkingTest.kt (com.sksamuel.kotest.property.shrinking) (I guess that's an reason why I cannot get automatic shrinking to work?)

It works in CI so I guess it must be your machine. Are you on windows?

@sam yup

Probably line endings are breaking it.

I can test this by using lf in the idea, right?

Not sure. You could update the tests and do a PR.

Oh, the test fails completely... It's not shrinking. The white text being printed is: Property test failed for inputs

I see.

Does that mean that I cannot expect the shrinking-steps this way, or does it mean that a bug crawled into the code?

Shrinking should work fine - this test just needs to be updated.

All the other tests are using the an shrinker explicitly (If I'm right). Therefor I believe automatic shrinking, so checkall, is not running properly.

Yeah makes sense.

related, I think ListShrinker in action is missing a

]

?

Not sure I understand.

ListShrinkerTest.kt:100 This tests, if the listshrinker starts with 4 numbers, I believe that without shrinking, it would also start with those 4 numbers.

I guess its a bit of a pointless test then

yes, this test should be updated. after shrinking, it should have the 4 numbers specified, but with the closing bracket:

[0, 1, 51, 24]

right, if you have time please open the PR

Ah, I understand now, It's written at the same day as the ShrinkingTest. It's not the responsibility of ListShrinker to know how the test is printed. Therefor it should be removed.

You could think of it as an integration test
