Given that Room supports Jvm thanks to KMP support.
In the context of a pure Android project, not using KMP.
Would it be possible to use Room Jvm runtime on Jvm unit tests?

I tried the following in an Android library Gradle module

implementation(libs.androidx.room.common)
    testImplementation(libs.androidx.room.runtime.jvm)
    testImplementation(libs.androidx.sqlite.jvm)
    testImplementation(libs.androidx.room.testing)

But the inMemoryDatabaseBuilder function references the Android Context, it comes from the Android runtime dependency despite not being referenced.

How could I manage to run Unit tests using Dao with in-memory DB on Jvm unit test with an Android library module?

Oh 🎉

I finally, managed to make it work.
I think, I had some Gradle sync/build cache issues at some point leading to false positive.

Here is the final setup to make it work

implementation(libs.androidx.room.common)

    testImplementation(libs.androidx.room.runtime.jvm)
    testImplementation(libs.androidx.sqlite.jvm)
    testImplementation(libs.androidx.sqlite.bundled.jvm)

db = Room.inMemoryDatabaseBuilder<UserPreferencesDatabase>()
    .setDriver(BundledSQLiteDriver())
    .build()
