We are going to repeat the same test driven development for 3 more tests. This’ll all be very good practice for you. The first tests is going to make sure that saveNewItem saves the correct data, remember that this test only verified that we saved something.

@Test
fun saveNewItemSavesData() {
    val wishlist = Wishlist("Victoria",
        listOf("RW Android Apprentice Book", "Android phone"), 1)
    val name = "Smart watch"
    viewModel.saveNewItem(wishlist, name)

    val mockObserver = mock<Observer<Wishlist>>()
    wishlistDao.findById(wishlist.id)
        .observeForever(mockObserver)
    verify(mockObserver).onChanged(
        wishlist.copy(wishes = wishlist.wishes + name))
}
wishlist.copy(wishes = wishlist.wishes + name)
@Test
fun getWishListCallsDatabase() {
  viewModel.getWishlist(1)

  verify(wishlistDao).findById(any())
}
