If I have a viewmodel which I define like so in my fragment.

private val viewModel by viewModel<MyViewModel>() { parametersOf(myParam) }

How do I pass a parameter when getting an instance of myViewModel in my test?

val vm = get<MyViewModel>()

If I get you right, the logic is the same.
For example this works for me just fine:

val vm: MyViewModel = KoinContextHandler.get().get { parametersOf(yourParams) }

I prefer though to override Koin module for tests. Not sure what exactly fits better for you.

yes, val vm = get<MyViewModel> { parametrsOf(...)}
