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
t

tieskedh

11/24/2020, 11:51 AM
the test in ShrinkingTest.kt (com.sksamuel.kotest.property.shrinking) (I guess that's an reason why I cannot get automatic shrinking to work?)
s

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

sam

Probably line endings are breaking it.
It will be looking for \n and on windows its \r\n

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

sam

11/24/2020, 2:21 PM
Not sure. You could update the tests and do a PR.
t

tieskedh

11/24/2020, 2:24 PM
Oh, the test fails completely... It's not shrinking. The white text being printed is: Property test failed for inputs

I see.
that test is disabled?
It looks like its was disabled due to some changes in the random stuff, and then forgotton about and never updated.
t

tieskedh

11/24/2020, 2:28 PM
Does that mean that I cannot expect the shrinking-steps this way, or does it mean that a bug crawled into the code?
s

sam

11/24/2020, 2:29 PM
Shrinking should work fine - this test just needs to be updated.
hmmmm actually it looks like shrinking is not being run
I see what you're saying now
t

tieskedh

11/24/2020, 2:35 PM
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.
s

sam

11/24/2020, 2:36 PM
Yeah makes sense.
t

tieskedh

11/24/2020, 2:43 PM
related, I think ListShrinker in action is missing a
]
?
s

sam

11/24/2020, 2:48 PM
Not sure I understand.
t

tieskedh

11/24/2020, 2:50 PM
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.
s

sam

11/24/2020, 2:51 PM
I guess its a bit of a pointless test then
t

tieskedh

11/24/2020, 2:55 PM
yes, this test should be updated. after shrinking, it should have the 4 numbers specified, but with the closing bracket:
[0, 1, 51, 24]
s

sam

11/24/2020, 3:01 PM
right, if you have time please open the PR
👍🏻 1
t

tieskedh

11/24/2020, 3:06 PM
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.
s

sam

11/24/2020, 3:07 PM
You could think of it as an integration test
t

tieskedh

11/24/2020, 3:42 PM
done
