Yes, but a big problem there is that you cannot alter bytecode of all dependencies, so mocking of final classes is quite annoying to implement

[shikasd]

And people love to mock their final classes 😅

[russhwolf]

Could you pass it through something like the all-open plugin first?

[Dominaezzz]

Ah, I mean like mocking interfaces and abstract classes. I feel, if one has to mock final classes then they probably need a redesign.

And people love to mock their final classes 😅

Very unfortunate

[shikasd]

I was thinking about it for some time, but just figured it isn't worth it (use stubs instead ;))
It is not that hard to integrate with mockk or similar frameworks though, if you really wanted to

[russhwolf]

Say what you will about mocking is bad, but there's still plenty of people using mockk on the JVM side who would love to have a compiler plugin to make it easier to migrate their tests to native.

[shikasd]

Yeah, I am just saying that I didn't want to invest in that myself, but happy to help if someone wants to take on this

[shikasd]

It isn't /very/ hard to create mocks for interfaces and abstract methods at compile time
The only limitation I remember about is resolution of generics if you want to support something like mockk<T> I saw used quite often

[Dominaezzz]

I'm interested in building this but don't want to do it by myself. Also don't know where to start with regards to project structure.

[Dominaezzz]

The generic one should be doable with some substitution in the plug in.
