I could not find Arb.create(fn) function in Kotest 5.8.0, even though it is still shown on the Generators List page of the docs.

Thanks, removed it from the docs

[Michael Strasser]

What should I use instead? I have been using Arb.bind() but only want to specify one Arb type. What am I missing?

[Emil Kantis]

Do you want a reflective arb for a certain type? Or do you have a value you want to turn into an Arb?

I want to generate exception classes with generated messages. I have this, because I don’t know better:

val genMessage = Arb.string(1, 120)
val genException = Arb.bind(listOf(genMessage)) { messages -> Exception(messages.first()).fillInStackTrace() }

Is there a better way to specify an exception generator?

[Emil Kantis]

maybe this?

val genException = Arb.string(1, 120).map { message -> Exception(message).fillInStackTrace() }

[Michael Strasser]

Thank you! I didn’t know about map() function. It shows I need to read more of the documentation.

No problem 🙂 sometimes it's easier to just ask 👍 fun to see property testing being used in other open-source projects.
