很抱歉这个超长的问题，我有点迷路了。
我可以很好地运行测试，但是在调试时它会卡在“实例化测试......”阶段。在我的控制台中，我看到以下日志输出。主要错误似乎是：
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)
我在代码或谷歌中找不到对 instrumentation.cc:267 的引用

这是成功运行测试的日志。具体来说，调试时失败的日志部分。

由此看来，添加这 3 个侦听器时似乎失败了
测试本身并不重要，因为它甚至没有到达测试的第一行。
它似乎失败的点很重要。我试图didStart()在我的类中模拟以下调用，App该调用是在创建我的 android Application 类时调用的。这是模拟对我的本机 android 库的调用的更大任务的一部分。
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()
...
}
}
为此，我对我的应用程序进行了子类化并添加了一些自定义 koin 加载以允许didStart()成功调用调用，然后我才有机会在测试本身中模拟事物。
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()
}
}
这是我的构建信息：
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"
androidTestImplementation "androidx.test:rules:1.2.0"
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
}
Android工作室信息如果有用吗？
