Component useds: androidx.room:room-ktx, androidx.room:room-testing Version used: 2.6.1 Devices/Android versions reproduced on: Robolectric

The definition of Room.inTransaction() is:

open fun inTransaction(): Boolean {
    return openHelper.writableDatabase.inTransaction()
}

This opens the db even if it wasn't previously open and doesn't close it. This is almost always going to be fine in production, but in tests it can cause a db leak, which is especially painful since it's called by room-internal code.

Since it's open, in my project I simply overrode it to be

override fun inTransaction(): Boolean {
    if (!isOpenInternal) return false
    return super.inTransaction()
}

which resolved the issue and is similar to a check that most, but not all, room-internal code does anyway.

Would be great to have this catch in the framework though, to prevent this issue for others
