SharedKmpTestConventionPlugin

Multiplatform sibling of SharedTestConventionPlugin: wires the shared test stack into commonTest, so it reaches every declared target, iOS included.

SharedTestConventionPlugin adds to testImplementation, which is the JVM/Android unit-test configuration only. On a module using shared.kmp.library / shared.kmp.compose that reaches neither iosArm64Test nor iosSimulatorArm64Test — an iOS test source set would compile against no test framework at all, silently, with nothing in the build failing to say so. Applying this plugin instead is what gives those source sets a stack.

Only the aliases that are genuinely multiplatform are wired here: kotlin-test, kotlinx-coroutines-test, turbine and koin-test. JUnit and MockK are JVM-only and stay in SharedTestConventionPlugin — putting them in commonTest would fail to resolve for the native targets. A module that needs both can apply both plugins.

Every alias is looked up in the consuming project's own version catalog via findLibrary(...).ifPresent {} (same pattern as SharedKoinConventionPlugin / SharedRoomConventionPlugin) and silently skipped when absent, so this repo's own catalog needs no test entries. The whole body is deferred behind pluginManager.withPlugin("org.jetbrains.kotlin.multiplatform"), so it is order-independent with respect to shared.kmp.library in the consumer's plugins {} block.

Apply with id("shared.kmp.test").
