This test case is designed to test the shopping cart system for a game store. The system should allow users to add daily and weekly limited props from the store to the shopping cart. Different props may require different game currencies (white diamonds and blue diamonds) for purchase. The shopping cart should have manual selection, full selection, currency type filtering, and limited type filtering. The shopping cart should also allow users to modify the number of props, delete props, and purchase all props with one click. The shopping cart should display the items, unit price, purchase quantity, remaining limited quantity, total amount of currency selected for props, and the remaining amount of two currencies of the player.
