org.koin.android.error.MissingAndroidContextException: when try to test app with context

Question

I want to write test for koin. I use RoomDatabase, which receives context in constructor. App works well but test fails

Can't resolve Application instance. Please use androidContext() function in your KoinApplication configuration.

Answer 1

if you want context in your modules, you should pass context in your start koin method

// start Koin!
    startKoin {

      // declare used Android context
      androidContext(this@MyApplication)

      // declare modules
      modules(yourModule)
    }

and use these libraries

    // Koin AndroidX Scope features
    implementation "org.koin:koin-android-scope:2.0.1"
// Koin AndroidX ViewModel features
    implementation 'org.koin:koin-androidx-viewmodel:2.0.1'
// Koin AndroidX Experimental features
    implementation "org.koin:koin-android-ext:2.0.1"
