Another weird thing, I added this below that Text

Kotlin code:

if (name != "unknown") Text(name)

This one does appear when the state updates, but the original Text still shows the old state

Anyone used mockk to mock extension functions on a singleton object before? I cant figure out any combination of mockkStatic or mockkObject that works. The specific thing I need to mock is google's firebase initialization, they've got it declared like

Kotlin code:

object Firebase

fun Firebase.initialize(context: Context): FirebaseApp? = FirebaseApp.initializeApp(context)

//some overloads below of that function that I'm not trying to mock for our tests

The documentation is this huge page with a few examples but it's not good https://mockk.io/#extension-functions
I don't know why google made those extension functions in the same file instead of just being part of the object either, real pain in the rear end. FirebaseApp is in java instead of kotlin

Forgot they have the source on github, this is the specific function I was trying to mock for tests

I'm trying to mock the initialize function, not a context param

You really aren't getting it

Trying to setup unit tests for this analytics implementation we have that relies on firebase. For whatever reason google wrote the functions on the firebase object as extension functions which is making it difficult or impossible to mock those functions. I'll probably end up wrapping all the calls with another object that just directly forwards them without any additional logic to minimize the amount of untested code.

Extension functions are pretty awkward in general for testing, since they don't actually "belong" to the object. Like if I had some type named Thing and in a file named Extensions.kt I wrote

Kotlin code:

// File is Extensions.kt

fun Thing.doIt(text: String) {
    // do whatever here
}

This results in some java code that looks something like

Java code:

public static class ExtensionsKt {
    public static void doIt(Thing thing, String text) {
        // do whatever here
    }
}

so the function is part of some entirely separate object and calls doIt on mock instances of Thing still go to the unmocked extension function. This is really annoying for reading unit tests because non-extensions on that object are mocked but extensions aren't.

Yeah you can just unzip an apk, though it sounds like this is a game so the game data might be in some framework-specific format instead of PNGs
