Not Able to mock methods called inside init block of a class

[rakshushetty]

I have a case where i need to call 3 api's once Screen is launched.
So I have written a method like this

fun fetchAllApis() {
    fetchApi1()
    fetchApi2()
    fetchApi3()
}

and this method is called inside init block of ViewModel

init {
   fetchAllApis()
}

Now the issue is, When i want to write unit test case for method fetchApi1() , I have to instantiate ViewModel which. internally calls init block and runs all the apis.
I want to mock init block. When ever I create instance of ViewModel, It should not call fetchAllApis() method.

Is there any way i can achieve this?

I tried by using constructor mock, but did work.

init blocks cannot be mocked.

Out of curiosity, why is your fetchAllApis() call in an init block rather than in a constructor?
