KmpTestData

KmpTestData is a Kotlin Multiplatform test-data project for IntelliJ IDEA KMP UI and acceptance tests.

Current Fixtures

Swift Completion

The Swift completion fixtures cover existing symbols available on project opening and edit-time anchors for symbols added after project opening. The consumer file intentionally keeps executable bodies empty; UI tests type code into these functions and assert completion lookup items.

Case	Consumer anchor	Source file	Typed prefix/code	Expected lookup items
Existing Swift type/enum	consumeExistingSwiftCompletion()	iosApp/iosApp/swiftTestFixtures/SwiftCompletionSource.swift	ExistingSource	ExistingSourceType, ExistingSourceMode
Existing Swift top-level value/function	consumeExistingSwiftCompletion()	iosApp/iosApp/swiftTestFixtures/SwiftCompletionSource.swift	existingTopLevel	existingTopLevelValue, existingTopLevelFunction
Existing Swift member	consumeExistingSwiftCompletion()	iosApp/iosApp/swiftTestFixtures/SwiftCompletionSource.swift	let source = ExistingSourceType(), source.existingMember	existingMemberValue, existingMemberFunction()
Existing Swift enum case	consumeExistingSwiftCompletion()	iosApp/iosApp/swiftTestFixtures/SwiftCompletionSource.swift	let mode: ExistingSourceMode = .existing	existingReady, existingPaused
Foundation type	consumeExistingSwiftModuleCompletion()	Foundation import in SwiftCompletionConsumer.swift	DateForm	DateFormatter
Swift stdlib type	consumeExistingSwiftModuleCompletion()	Swift standard library	Dictio	Dictionary
Swift keyword	consumeExistingSwiftModuleCompletion()	Swift language keywords	fun	func
Added Swift type/enum	consumeAddedSwiftCompletion()	Runtime-created iosApp/iosApp/swiftTestFixtures/AddedSwiftCompletionSource.swift	AddedSource	AddedSourceType, AddedSourceMode
Added Swift top-level value/function	consumeAddedSwiftCompletion()	Runtime-created AddedSwiftCompletionSource.swift	addedTopLevel	addedTopLevelValue, addedTopLevelFunction
Added Swift member	consumeAddedSwiftCompletion()	Runtime-created AddedSwiftCompletionSource.swift	let source = AddedSourceType(), source.addedMember	addedMemberValue, addedMemberFunction()
Added Swift enum case	consumeAddedSwiftCompletion()	Runtime-created AddedSwiftCompletionSource.swift	let mode: AddedSourceMode = .added	addedReady, addedPaused

Swift ↔ Kotlin Completion

The cross-language completion fixtures cover Kotlin declarations exported to Swift from the Shared framework. Existing Kotlin declarations live under iosMain because these scenarios target Swift/iOS export behavior.

Case	Consumer anchor	Source file	Typed prefix/code	Expected lookup items
Existing Kotlin file facade	consumeExistingKotlinCompletion()	shared/src/iosMain/kotlin/org/jetbrains/kmptestdata/kotlinTestFixtures/KotlinCompletionSource.kt	KotlinCompletionSource	KotlinCompletionSourceKt
Existing Kotlin type/interface/enum	consumeExistingKotlinCompletion()	KotlinCompletionSource.kt	ExistingKotlinSource	ExistingKotlinSourceType, ExistingKotlinSourceContract, ExistingKotlinSourceMode
Existing Kotlin class member	consumeExistingKotlinCompletion()	KotlinCompletionSource.kt	let source = ExistingKotlinSourceType(), source.existingKotlinMember	existingKotlinMemberValue, existingKotlinMemberFunction()
Existing Kotlin interface member	consumeExistingKotlinCompletion()	KotlinCompletionSource.kt	let source: ExistingKotlinSourceContract, source.existingKotlinContract	existingKotlinContractFunction()
Existing Kotlin enum case	consumeExistingKotlinCompletion()	KotlinCompletionSource.kt	let mode: ExistingKotlinSourceMode = .existing	existingReady, existingPaused
Existing Kotlin top-level function	consumeExistingKotlinCompletion()	KotlinCompletionSource.kt	KotlinCompletionSourceKt.existingKotlinTopLevel	existingKotlinTopLevelFunction()
Added Kotlin file facade	consumeAddedKotlinCompletion()	Runtime-created shared/src/iosMain/kotlin/org/jetbrains/kmptestdata/kotlinTestFixtures/AddedKotlinCompletionSource.kt	AddedKotlinCompletionSource	AddedKotlinCompletionSourceKt
Added Kotlin type/interface/enum	consumeAddedKotlinCompletion()	Runtime-created AddedKotlinCompletionSource.kt	AddedKotlinSource	AddedKotlinSourceType, AddedKotlinSourceContract, AddedKotlinSourceMode
Added Kotlin class member	consumeAddedKotlinCompletion()	Runtime-created AddedKotlinCompletionSource.kt	let source = AddedKotlinSourceType(), source.addedKotlinMember	addedKotlinMemberValue, addedKotlinMemberFunction()
Added Kotlin interface member	consumeAddedKotlinCompletion()	Runtime-created AddedKotlinCompletionSource.kt	let source: AddedKotlinSourceContract, source.addedKotlinContract	addedKotlinContractFunction()
Added Kotlin enum case	consumeAddedKotlinCompletion()	Runtime-created AddedKotlinCompletionSource.kt	let mode: AddedKotlinSourceMode = .added	addedReady, addedPaused
Added Kotlin top-level function	consumeAddedKotlinCompletion()	Runtime-created AddedKotlinCompletionSource.kt	AddedKotlinCompletionSourceKt.addedKotlinTopLevel	addedKotlinTopLevelFunction()

Swift Super-Gutter Navigation

The current fixture set covers Swift super-gutter navigation from Swift implementations to Kotlin and Swift super declarations. The multiple-choice fixture uses one Swift method that satisfies both a Kotlin-exported protocol (Repository) and a native Swift protocol (SwiftRepositoryContract), so the gutter opens a dropdown where the test chooses the target declaration.

Case	Source file	Gutter anchor	Expected destination	Chooser item
Kotlin interface implementation	iosApp/iosApp/swiftTestFixtures/SwiftRepository.swift	func fetchData(id: String) -> String	shared/src/commonMain/kotlin/org/jetbrains/kmptestdata/shared/Repository.kt, fun fetchData(id: String): String	none
Dropdown to Kotlin protocol declaration	iosApp/iosApp/swiftTestFixtures/SwiftRepositoryMultipleChoice.swift	func fetchData(id: String) -> String	shared/src/commonMain/kotlin/org/jetbrains/kmptestdata/shared/Repository.kt, fun fetchData(id: String): String	fetchData(String)
Dropdown to Swift protocol declaration	iosApp/iosApp/swiftTestFixtures/SwiftRepositoryMultipleChoice.swift	func fetchData(id: String) -> String	iosApp/iosApp/swiftTestFixtures/SwiftRepository.swift, func fetchData(id: String) -> String	SwiftRepositoryContract

The Kotlin fixture declaration is in shared/src/commonMain/kotlin/org/jetbrains/kmptestdata/shared/Repository.kt. The Swift super-gutter fixtures are in iosApp/iosApp/swiftTestFixtures/SwiftRepository.swift and iosApp/iosApp/swiftTestFixtures/SwiftRepositoryMultipleChoice.swift.

Maintenance Rules

• Keep fixture files small and explicit. Add only declarations that are covered by UI tests or planned near-term tests.
• When a fixture changes, update the corresponding UI test data and this README in the same change.
• Prefer adding new focused files for new scenario groups over expanding existing files with unrelated declarations.

Running

• Android app: ./gradlew :androidApp:assembleDebug
• Shared Android host tests: ./gradlew :shared:testAndroidHostTest
• iOS framework compilation: ./gradlew :shared:compileKotlinIosSimulatorArm64
• iOS app: open iosApp in Xcode and run the iosApp scheme.
