17-33: Test coverage for label collection is appropriate.The test
WHEN_label_emitted_THEN_label_collectedcorrectly verifies that labels emitted by theStoreare collected by the flow. The use ofCoroutineScopeandDispatchers.Unconfinedis suitable for testing. Ensure that these tests run in isolation to avoid side effects.
35-48: Test for cancellation behavior is well-implemented.The test
WHEN_collection_cancelled_THEN_unsubscribed_from_storeverifies that the store unsubscribes when the coroutine scope is cancelled. This ensures proper resource cleanup.
50-76:TestStoremock implementation is sufficient.The
TestStoreclass provides a minimal implementation of theStoreinterface necessary for testing. The use oflabelObserverto track subscriptions is effective for verifying behavior.mvikotlin-extensions-coroutines/src/commonTest/kotlin/com/arkivanov/mvikotlin/extensions/coroutines/LabelChannelTest.kt (4)
21-40: Test for label collection via channel is effective.The test
WHEN_label_emitted_THEN_label_collectedverifies that labels emitted by theStoreare collected by the channel. The test setup and assertions are clear and appropriate.
42-57: Test for scope cancellation and unsubscription is correct.The test
WHEN_scope_cancelled_THEN_unsubscribed_from_storeensures that the store unsubscribes when the coroutine scope is cancelled. This is crucial for resource management.
59-75: Channel cancellation test is well-structured.The test
WHEN_scope_cancelled_THEN_channel_cancelledchecks that the channel is closed when the scope is cancelled. This confirms the proper handling of channel lifecycle.
77-103: Reuse ofTestStoreis appropriate.The
TestStoreclass is reused effectively to mock theStoreinterface for testing purposes. It provides necessary functionality for the tests without unnecessary complexity.mvikotlin-extensions-coroutines/src/commonMain/kotlin/com/arkivanov/mvikotlin/extensions/coroutines/StoreExt.kt (2)
82-95: Documentation forlabelsChannelis clear and informative.The documentation provides a thorough explanation of the
labelsChannelfunction, its use cases, and its parameters. It effectively differentiates betweenFlowandReceiveChannel, aiding developers in choosing the appropriate tool for their needs.
96-114: Implementation oflabelsChannelis robust and well-structured.The
labelsChannelfunction is implemented with careful attention to coroutine and channel lifecycle management. The use ofawaitCancellationand thetry-finallyblock ensures proper resource cleanup.

69-69: Ensure proper documentation forlabelsChannel.The
labelsChannelfunction is a new addition to the API. Ensure that it is well-documented, explaining its purpose, parameters, and usage scenarios to aid developers in understanding its functionality.mvikotlin-extensions-coroutines/api/jvm/mvikotlin-extensions-coroutines.api (1)
69-69: Ensure consistent documentation forlabelsChannel.The
labelsChannelfunction should have consistent documentation across different platforms (Android and JVM) to maintain clarity and uniformity in the API.

labelsChannel$defaultfunction behaves consistently across different platforms and that its default parameters are correctly set for the JVM context.Verification successful
labelsChannel$defaultappears consistent and correct. The functionlabelsChannelinStoreExt.kthas default parameters, andlabelsChannel$defaultis likely a synthetic method generated by the Kotlin compiler to manage these defaults.
