I'm trying to mock private properties from in a companion object. When I run the tests they throw an exception. io.mockk.MockKException: can't find property workerHandler for dynamic property get

I think it may be an issue with the fact that the first argument for mockkObject is vararg, so if you call it the way you do the second parameter is part of the vararg

[Mattia Tommasone]

it should be working if you write it as mockkObject(GeoJsonSource.Companion, recordPrivateCalls = true)

[mkrussel]

When I switch to that I get Missing mocked calls inside every { ... } block: make sure the object inside the block is a mock which is what I got before adding the true argument.

So it is the mocking of the mainHandler that fails, The workerHandler passes. Looking at the decompiled code, the mainHandler is turned into a static field of the GeoJsonSource class and there is no getter in the Companion object.
