/**
 * @brief Creates simple tile group for testing purposes.
 * @param backend Backend for tile group to use.
 * @param tuple_count Tuple capacity of this tile group.
 *
 * Tile group has two tiles, and each of them has two columns.
 * The first two columns have INTEGER types, the last two have TINYINT
 * and VARCHAR.
 *
 * IMPORTANT: If you modify this function, it is your responsibility to
 *            fix any affected test cases. Test cases may be depending
 *            on things like the specific number of tiles in this group.
 *
 * @return Pointer to tile group.
