#**Context:** The chunk is part of the ServiceNow Automated Test Framework (ATF) API documentation focusing on catalog and shopping cart functionalities such as searching for catalog items or record producers, adding them to a shopping cart, checking out the cart to create requests, and replaying request items. These APIs are used to automate the testing of catalog-related processes within ServiceNow applications.
```typescript
// Perform search for a Catalog Item or Record Producer in the specified Catalog and Category
atf.server.searchForCatalogItem({ // all props are mandatory
    $id: Now.ID[''], // string | guid, mandatory
    searchInPortal: true, // boolean;
    searchTerm: '', string;
    catalog: get_sys_id('sc_catalog', ''), // sys_id | Record<'sc_catalog'>;
    category: get_sys_id('sc_category', ''), // sys_id | Record<'sc_category'>;
    assertItem: get_sys_id('sc_cat_item', ''), // sys_id | Record<'sc_cat_item'>;
    assert: '', // 'assert_item_present' | 'assert_item_not_present';
}): { catalogItemId: string; };

// Checkout the Shopping Cart and generates a new request.
atf.server.checkoutShoppingCart({ // all props are mandatory
    $id: Now.ID[''], // string | guid, mandatory
    assert: '', // 'empty_cart' | 'checkout_successfull'
    requestedFor: get_sys_id('sys_user', ''), // sys_id | Record<'sys_user'>
    deliveryAddress: '123 main st', // string
    specialInstructions: 'none', // string
}): { requestId: string; };

// Replays a previously created request item with the same values and options.
atf.server.replayRequestItem({ 
    $id: Now.ID[''], // string | guid, mandatory
    requestItem: get_sys_id('sc_req_item', ''), // sys_id | Record<'sc_req_item'>;
}): {
    table: string;
    reqItem: sys_id | Record<'sc_req_item'>;
};
