How to test Koin in Android?

Testing Koin in Android

Koin is a popular dependency injection framework for Kotlin applications, particularly in Android. Testing Koin involves ensuring that your components are correctly injected and that their dependencies are properly managed.

In this guide, we discuss how to set up Koin in your Android project and test your modules effectively.

Setting Up Koin

To start using Koin, you should first define your modules and start Koin in your application class. For example:

import org.koin.core.context.startKoin import org.koin.dsl.module val appModule = module { single { MyRepository() } viewModel { MyViewModel(get()) } } class MyApplication : Application() { override fun onCreate() { super.onCreate() startKoin { modules(appModule) } } }

Testing Koin Components

To test your Koin setup, you can use Koin's testing functions. Below is an example of how to test your ViewModel with Koin:

import org.koin.test.KoinTest import org.koin.test.inject import org.junit.Before import org.junit.Test class MyViewModelTest : KoinTest { private val myViewModel: MyViewModel by inject() @Before fun setup() { startKoin { modules(appModule) } } @Test fun testMyViewModel() { val data = myViewModel.getData() // Assert the expected results assert(data.isNotEmpty()) } }
