Bug: Mocking varargs about mockk HOT 10 CLOSED

In version 1.8 it should be fixed. Please check

from mockk.

Look like issue is appearing when using interface or abstract class. When using simple class it is passing:

    class Foo {
        fun foo(vararg args: String, otherArg: String) {

        }
        fun foo(args: List<String>, otherArg: String) {
            
        }
    }

I've checked underlying reflection call and seems Kotlin is just not returning correct value. So it is a Kotlin reflection API bug

from mockk.

After additional checking, it appears that pure interface is working. So it is related to metadata propagation i.e. while using interface MockK needs to create a proxy subclass and Kotlin metadata is not copied to that subclass.

from mockk.

So yes this because of subclassing. issue52 branch fixes it but makes builds 25% slower. This is something to solve additionally.

@oleksiyp I cannot verify vararg, method with vararg always fail verification (except verify(exactly = 0), just because of it never called)
Can you confirm, that this is related to this issue or I do something wrong?

from mockk.

Very probable that this is related.
Fix/workaround is making MockK slow, so it was not merged.
Some caching to be applied.
Or maybe other ways to fix it.

Right now(one/two weeks) I'm quite free for doing MockK improvements/fixes but focused on Android instrumentation test which is a big feature. Will get back to such not very big things after releasing it.

I desperately need good co-author :-)

Seems it was fixed, reopen if it is not
