Multiplatform ViewModels + * + * This file documents the testing patterns and solutions implemented in this project + * to address common ViewModel testing challenges in Kotlin Multiplatform projects. + * + * ## Problems Solved + * + * ### 1. Protected onCleared() Method Access + * **Problem**: Cannot directly call ViewModel.onCleared() in tests as it's protected + * **Solution**: + * - Implement TestableViewModel interface with clearViewModel() method + * - ViewModels expose public clearViewModel() that calls onCleared() internally + * - Tests call clearViewModel() instead of onCleared() + * + * ### 2. ViewModel Lifecycle Testing + * **Problem**: Need to properly test ViewModel lifecycle and resource cleanup + * **Solution**: + * - Use TestScope instead of viewModelScope for testing + * - Provide optional CoroutineScope parameter in ViewModel constructor + * - Implement proper cleanup in clearViewModel() method + * - Test coroutine cancellation and resource cleanup + * + * ### 3. SecurityHelper Mocking Issues + * **Problem**: Cannot mock SecurityHelper with traditional mocking frameworks + * **Solution**: + * - Create interface-based architecture (SecurityHelper interface) + * - Implement production version (SecurityHelperImpl) + * - Create test doubles (TestSecurityHelper) with verification capabilities + * - Use Koin dependency injection for easy test/production switching + * + * ### 4. PlatformAudioPlayer Constructor and Final Method Issues + * **Problem**: Platform-specific classes are final or have complex constructors + * **Solution**: + * - Create platform-agnostic interface (PlatformAudioPlayer) + * - Use expect/actual pattern for platform implementations + * - Make platform implementations open (non-final) where possible + * - Create simple test doubles that implement the interface + * - Use dependency injection to provide different implementations + * + * ## Best Practices Implemented + * + * ### Constructor Dependency Injection + * ```kotlin + * class TextEditorViewModel( + * private val securityHelper: SecurityHelper, + * private val audioPlayer: PlatformAudioPlayer, + * private val noteRepository: NoteRepository, + * private val coroutineScope: CoroutineScope? = null // Optional for testing + * ) : ViewModel(), TestableViewModel + * ``` + * + * ### Interface-Based Dependencies + * - All dependencies are interfaces, not concrete classes + * - Easy to create test doubles + * - Clear contracts and separation of concerns + * + * ### Test Scope Management + * ```kotlin + * // In tests + * private val testDispatcher = StandardTestDispatcher() + * private val testScope = TestScope(testDispatcher) + * + * // In ViewModel constructor + * private val effectiveScope = coroutineScope ?: viewModelScope + * ``` + * + * ### Proper Cleanup Testing + * ```kotlin + * @Test + * fun `ViewModel should properly manage coroutines lifecycle`() = testScope.runTest { + * viewModel.onProcessIntent(TextEditorIntent.StartLongRunningTask) + * advanceTimeBy(100) + * viewModel.clearViewModel() // Test cleanup + * advanceUntilIdle() + * // Verify no crashes and operations are cancelled + * } + * ``` + * + * ### State Flow Testing Utilities + * ```kotlin + * // Custom utility functions for StateFlow testing + * viewModel.uiState.assertEmits(expectedState, timeoutMs = 1000L) + * val state = viewModel.uiState.awaitValue { it.isLoading == false } + * ``` + * + * ## Test Structure + * + * ### Test Module Setup + * ```kotlin + * val testModule = module { + * single { TestSecurityHelper() } + * single { TestPlatformAudioPlayer() } + * single { TestNoteRepository() } + * } + * ``` + * + * ### Test Lifecycle Management + * ```kotlin + * @BeforeTest + * fun setup() { + * Dispatchers.setMain(testDispatcher) + * startKoin { modules(testModule) } + * viewModel = TextEditorViewModel(...) + * } + * + * @AfterTest + * fun tearDown() { + * viewModel.clearViewModel() + * stopKoin() + * Dispatchers.resetMain() + * } + * ``` + * + * ## File Organization + * + * ### Production Code + * - `domain/` - Interfaces and models + * - `data/` - Implementations + * - `presentation/` - ViewModels + * - `di/` - Dependency injection modules + * + * ### Test Code + * - `commonTest/` - Shared tests + * - `testutil/` - Testing utilities and helpers + * - Test doubles in same package as tests that use them + * + * ## Integration with Build System + * + * The testing setup integrates with: + * - Kotlin Multiplatform test source sets + * - Koin dependency injection testing + * - Coroutines testing framework + * - kotlinx-datetime for time-based testing + * + * ## Verification + * + * All solutions maintain: + * - Production code remains clean and uncompromised + * -
