Upgrading a repo from kotlintest to kotest, is it possible to do property testing with just a specific set of values? (like kotlintest had)

[sam]

You mean you want to hard code some values ?

[bbaldino]

Yeah, I had:

forall(
    row(1, 10, -9),
    row(10, 1, 9),
    row(1, 32760, 9),
    row(32760, 1, -9),
    row(1234, 1234, 0)
) { a, b, expected ->
                    Vp8Utils.getExtendedPictureIdDelta(a, b) shouldBe expected
}

[bbaldino]

a generic one doesn't make much sense here, as in order to verify I'd have to do the same logic I'm testing

[sam]

Arb.element(1,2,3)

[sam]

you can pass in a collection or vararg

[sam]

Same thing as Arb.of but I think that's 4.2 only

[bbaldino]

So in this case each element would have to be the three values?

[sam]

no, it's vararg

[bbaldino]

Hm, ok...might be less clear this way. Maybe I'll just write them out

[sam]

Your example was not a property test but a data test

[sam]

so did you mean data testing in kotest ?

[bbaldino]

Ah! Yes, I guess I got the terms crossed.

[sam]

should be the same. If you're using a newer version, you might need to flip forall to forAll

[bbaldino]

Oh, great, ok thanks Sam!

[sam]

The lower case version was a hold over from Scala
