Restore triggerBiometricDataInvalidated() to maintain testing capabilities
The removal of this method has created a critical gap in testing functionality:
- The
isBiometricDataInvalidatedflag can only be set to false viaclearStoredData()- There's no way to trigger the biometric invalidation state for testing
UnlockViewModelrelies on this functionality for handling biometric invalidation scenarios🔗 Analysis chain

34-38: LGTM! Consider architectural improvements for better testability.The lazy initialization using BiometricResolver is well implemented. However, consider these architectural improvements:
- Consider injecting the BiometricResolver through constructor or property injection instead of using GlobalInjector for better testability
- Consider adding error handling for the chain of calls

3-5: Add KDoc documentation to explain the purpose of this interface.Consider adding documentation to explain:
- The purpose of this resolver interface
- The role of the
getInteractor()method- Any threading/lifecycle considerations
+/** + * Resolves and provides access to biometric authentication functionality. + * This interface allows for dynamic resolution of biometric interactors, + * enabling hot-reloading in debug builds. + */ interface BiometricResolver { + /** + * Returns the biometric interactor instance. + * @return BiometricInteractor implementation + */ fun getInteractor(): BiometricInteractor }app/src/main/kotlin/com/ivanovsky/passnotes/domain/biometric/BiometricResolverImpl.kt (1)
5-12: Document thread safety guarantees.The implementation looks good. Consider adding documentation about thread safety, especially since this class might be accessed from different threads.
+/** + * Default implementation of BiometricResolver that creates and caches + * a single BiometricInteractor instance. + * + * Thread-safety: This implementation is thread-safe as it initializes + * the interactor instance during construction and only provides read-only + * access to it. + */ class BiometricResolverImpl( context: Context ) : BiometricResolver {app/src/main/kotlin/com/ivanovsky/passnotes/injection/modules/debug/DebugBiometricModule.kt (1)
7-13: Add documentation explaining the purpose of this debug module.Consider adding documentation to explain:
- The purpose of this debug-specific module
- When and how it should be used
- How it differs from the regular BiometricModule

22-22: LGTM! Consider renaming to align with refactoring.The removal of "(requires restart)" aligns well with the hot reload implementation. However, to maintain consistency with the broader refactoring pattern mentioned in the PR summary, consider renaming from "Fake" to "Debug".
Apply this diff to align with the new naming pattern:
- <string name="fake_biometric_enabled" translatable="false">Use Fake Biometric</string> + <string name="debug_biometric_enabled" translatable="false">Use Debug Biometric</string>

3-5: Great use of Kotlin's functional interface!Converting to a functional interface is a good improvement as it enables more concise lambda syntax for single-method interfaces, reducing boilerplate code while maintaining the same functionality. This change aligns well with Kotlin's idioms and best practices.
app/src/main/kotlin/com/ivanovsky/passnotes/presentation/unlock/UnlockFragment.kt (1)
13-14: LGTM! Import changes align with the new BiometricResolver pattern.The import changes correctly reflect the architectural shift from direct BiometricAuthenticator usage to the new BiometricResolver pattern.
app/src/main/kotlin/com/ivanovsky/passnotes/presentation/groups/GroupsFragment.kt (4)
20-20: LGTM!The new imports are correctly added to support the BiometricResolver pattern implementation.
Also applies to: 22-22
53-57: LGTM!Properties are well-organized at the top of the class following Kotlin best practices.
59-65: LGTM!The ViewModel initialization is simplified using the indexing operator while maintaining the same functionality.
68-72: Verify BiometricResolver integration.The change to use BiometricResolver improves flexibility and aligns with the hot reload implementation. However, let's verify the integration across the codebase.
✅ Verification successful
BiometricResolver integration is properly implemented ✅
The codebase shows consistent usage of BiometricResolver across all relevant components, with proper dependency injection and a clean architecture that supports both production and debug implementations. The changes align well with the hot reload implementation goal.

9-9: LGTM! Interface change aligns with resolver pattern.The addition of
getAuthenticator()method and removal ofisBiometricSupported()reflects a good architectural decision to move towards a more flexible resolver pattern, which will better support hot reloading of the Debug biometrics module.app/src/debug/kotlin/com/ivanovsky/passnotes/injection/DebugModuleBuilder.kt (1)
11-11: LGTM! Module builder changes support hot reload.The simplification of module loading by directly including
DebugBiometricModuleand removing conditional logic is a good change that aligns with the hot reload capability objective.Also applies to: 33-33
app/src/main/kotlin/com/ivanovsky/passnotes/domain/biometric/BiometricInteractorImpl.kt (1)
18-20: LGTM! Clean implementation of BiometricInteractor changes.The implementation properly encapsulates the authenticator and provides a clean implementation of the new interface method.
app/src/main/kotlin/com/ivanovsky/passnotes/domain/test/biometric/DebugBiometricInteractorImpl.kt (1)
13-15: LGTM! Clean implementation with proper dependency injection.The implementation properly injects the ResourceProvider and maintains clean encapsulation of the authenticator.
Also applies to: 19-19, 22-22
app/src/main/kotlin/com/ivanovsky/passnotes/domain/test/usecases/DebugBiometricResolverImpl.kt (4)
20-31: LGTM! Clean initialization and proper listener registration.The constructor parameters and initialization logic are well-structured. The class properly initializes the mutable holder and settings listener, and registers the listener in the init block.
35-44: LGTM! Efficient settings change handling.The settings change listener is focused and only triggers a reload when the relevant setting (
TEST_TOGGLES) changes. The reload mechanism efficiently updates the underlying interactor through the mutable holder.
46-56: LGTM! Clear interactor instantiation logic with good logging.The instantiation logic is clear and well-documented with logging. The method properly handles the debug vs. regular interactor creation based on settings.
58-80: LGTM! Thread-safe mutable holder implementation.The
MutableInteractorHolderimplementation:
- Uses
MutableStateFlowfor thread-safe updates- Properly delegates all
BiometricInteractormethods- Maintains encapsulation of the underlying interactor
app/src/main/kotlin/com/ivanovsky/passnotes/presentation/settings/app/AppSettingsViewModel.kt (1)
11-11: LGTM! Clean transition to BiometricResolver pattern.The changes correctly implement the transition from direct
BiometricInteractorusage to the resolver pattern:
- Updated import statement
- Updated constructor parameter
- Properly chained
getInteractor()call to access biometric functionalityAlso applies to: 22-22, 44-45
app/src/main/kotlin/com/ivanovsky/passnotes/presentation/unlock/UnlockViewModel.kt (1)
30-30: LGTM! Consistent implementation of BiometricResolver pattern.The changes systematically implement the resolver pattern across the ViewModel:
- Updated import and constructor parameter
- Consistently used
getInteractor()to access biometric functionality- Updated biometric availability check

app/src/main/kotlin/com/ivanovsky/passnotes/presentation/groups/GroupsViewModel.kt (1)
33-33: LGTM! Optimized BiometricResolver usage.The changes efficiently implement the resolver pattern by caching the interactor:
private val biometricInteractor = biometricResolver.getInteractor()This optimization avoids repeated calls to
getInteractor()and improves performance.Also applies to: 108-108, 185-185

34-34: Verify the removal of runtime biometric module configuration.The change removes the ability to switch between different biometric modules at runtime using settings. Please confirm if this is intentional and that test scenarios requiring different biometric configurations are still supported.
Let's check if there are any test dependencies on this configuration:
✅ Verification successful
Runtime biometric configuration removal is intentional and safe
The change moves from runtime toggle to compile-time module selection, where debug builds use
DebugBiometricModuleand production builds use standardBiometricModule. This approach is cleaner and test scenarios are still fully supported through build variants rather than runtime toggles.🏁 Scripts executed
