Sorry for the super long question, i'm a bit lost.
I can run the test fine, however when debugging it gets stuck at the 'instantiating tests...' phase. In my console i see the below log output. The main error seems to be:
A/xxxx.xxxx.debu: instrumentation.cc:267] Check failed: m == frame.method_ (m=0x72c770c558, frame.method_=0x6feec140) Expected void java.lang.Object.wait(long, int), Found void java.lang.Object.wait(long, int)
I can find no reference to instrumentation.cc:267 in code or in google

Here's the logs from a successful run of the test. Specifically, the section of logs where it fails when debugging.

From this, it looks like its failing when adding those 3 listeners
The test itself is unimportant as its not even reaching the first line of the test.
The point at which it seems to fail is important. I'm trying to mock the following didStart() call in my App class which is called when my android Application class is created. This is part of a larger task to mock out the calls to my native android library.
class App constructor (val self: Long) {
companion object {
init {
try {
System.loadLibrary("android")
} catch (e: UnsatisfiedLinkError) {
System.err.println("Native code library failed to load when creating ${this.javaClass.name} ")
e.printStackTrace()
exitProcess(1)
}
}
@JvmStatic private external fun _did_start(self: Long)
}
fun didStart() {
App._did_start(self)
}
}
abstract class MyApp: Application() {
private val rustApp: RustApp by inject()
fun setup() {
rustApp.didStart()
...
}
}
To do this, I've subclassed my app and added some custom koin loading to allow the didStart() call to be called successfully, before i get the chance to mock things within the test itself.
class MyAppEspresso : MyApp() {
override fun onCreate() {
super.onCreate()
startKoin {
androidLogger()
androidContext(this@MyAppEspresso)
modules(listOf(module {
single {
mockk<App>() {
every { didStart() } returns Unit
}
}
}))
}
super.setup()
}
}
Here's my build info:
dependencies {
...
androidTestImplementation "io.mockk:mockk-android:1.10.0"
androidTestImplementation "androidx.test.espresso:espresso-core:3.2.0"
androidTestImplementation "androidx.test:runner:1.2.0"

}
Android studio info if thats useful?
