Replace the hand-written CharacterRepository fakes in the ViewModel and
UseCase unit tests with MockK mocks (coEvery / coVerify). This is a
deliberate showcase of MockK and intentionally diverges from the repo's
"prefer fakes over mocks" guidance.
- Add io.mockk:mockk 1.14.3 to the version catalog and the unit-test bundle;
add it explicitly to DomainModuleConventionPlugin (domain does not consume
the bundle).
- CharacterListViewModelTest: strict mockk, per-page coEvery stubs; the
paging/in-flight guards are expressed via coVerify(exactly = ...) and
coVerifyOrder instead of fake call counters.
- CharacterDetailViewModelTest: relaxed mockk so "missing id" needs no
stubbing; explicit coEvery elsewhere.
- GetCharactersPageUseCaseTest: mockk + coVerify replaces the inline fake.
- Move character()/characterDetails() fixtures to CharacterFixtures.kt and
delete FakeCharacterRepository.kt.
- NetworkCharacterRepositoryTest stays on Ktor MockEngine (MockK is for
Kotlin collaborator interfaces, not the HTTP transport).
Add an architecture.android.unit.test convention plugin that runs local unit
tests on the JUnit5 platform via useJUnitPlatform() (AndroidUnitTest extends
Gradle's Test) + the unit-test bundle. Deliberately NOT using the
de.mannodermaus plugin (targets AGP 8.x; we're on AGP 9). Add
junit-platform-launcher (Gradle 9 dropped the bundled launcher); set the
instrumentation runner; add a compose-ui-test bundle pinning espresso/runner to
current versions (transitive espresso 3.5.0 calls the removed
InputManager.getInstance() on API 34+). CI now runs ./gradlew test and compiles
the instrumented tests. Drop unused testing catalog entries.
Add a CharacterDetail MVI stack (State/Action/Event/ViewModel + CharacterDetailUi)
to the UI-agnostic :feature:characters:presentation. The detail ViewModel reads the
typed characterId from SavedStateHandle (populated by the type-safe CharacterDetailRoute),
so the module keeps zero navigation/Compose deps.
Add CharacterDetailScreen (Root/Screen, image header, attribute rows, loading/error)
and CharacterDetailRoute to :presentation-compose; refactor charactersGraph to drive
list->detail via NavController and expose About / Views entries as callbacks. Extract
shared CharacterStatus label/colour helpers; add an overflow menu to the list app bar.
Add material-icons-core to the compose bundle for the app-bar icons.
- CharacterListState (characters, isLoading, isLoadingNextPage, currentPage, endReached, error: UiText?),
CharacterListAction (OnCharacterClick/OnRetry/OnLoadNextPage), CharacterListEvent (NavigateToDetail/ShowSnackbar).
- CharacterListViewModel: state via .update, one-time events via Channel, DataError -> UiText on failure,
pagination persisted in SavedStateHandle (rebuilds list up to the saved page after process death).
- CharacterUi + Character.toCharacterUi().
- NO Compose/Views deps: verified no androidx.compose on the compile classpath. Stability via
ImmutableList instead of @Stable (which would require compose-runtime) — the only compose-named
transitive is kotlinx-immutable's annotations-only stub, not the Compose framework.
Android-only project, so Timber (the de-facto Android logging lib) fits better than the
KMP-oriented Kermit.
- Catalog: kermit -> timber (com.jakewharton.timber:timber 5.0.1).
- core:data: Ktor Logging bridged to Timber; safeCall logs via Timber.
- app: plant Timber.DebugTree() in debug only (buildConfig enabled for BuildConfig.DEBUG).
Foundation milestone (REDI-78, REDI-79):
- Multi-module skeleton: :app, :core:{domain,data,presentation,design-system},
:feature:characters:{domain,data,presentation,presentation-compose,presentation-views},
:feature:about:presentation, plus the :build-logic composite build.
- gradle/libs.versions.toml as the single source of truth ([versions]/[libraries]/
[bundles]/[plugins]); no inline versions in any build file.
- Convention plugins: architecture.android.{application,library,feature,feature.views},
domain.module, compose, koin, ktor, kotlinx.serialization.
- Pure-Kotlin domain modules; presentation-compose uses android.feature;
presentation-views uses android.feature.views (ViewBinding on, Compose off);
the UI-agnostic :presentation has neither Compose nor Views deps.
- Toolchain: AGP 9.0.1, Kotlin 2.3.20, Gradle 9.1.0, compileSdk 36, minSdk 24, Java 17.
- Minimal MainActivity placeholder; CI (assembleDebug) via GitHub Actions.
Verified: ./gradlew projects lists the full tree and ./gradlew assemble is green.
