Hey guys, any advice on mocking in commonTest? I tried mockk without success

As far as I know there are no multiplatform solutions yet. Mockk is working on support for iOS and JS, but it’s not ready yet. When writing multiplatform apps interfaces and fake are your best friends in tests 🙂 You will write a little bit more code than with mockk, but I think it is a good practice to prefer fakes vs mocks
Here is the interesting article about it:

Here you can see my approach:

I would also recommend plugin `Kotlin Fill Class`:
https://plugins.jetbrains.com/plugin/10942-kotlin-fill-class
for faster class constructor filling with default values and multiline (option+CMD+shift+left click) editing

You can't mock in common tests. I recommend the following article: https://medium.com/@june.pravin/mocking-is-not-practical-use-fakes-e30cc6eaaf4e
