**Criteria for method addItem:**

- Type of parameter for addItem

- Item already exists

- Total number of items in the inventory


**Criteria for searchItem and availabilityItem methods:**
- Type of parameter for searchItem and availabilityItem methods

- Item not exists

**Criteria for method new Item:**
- Couple of types of parameters (in oreder) for new Item

- Sign of quantity

**Criteria for method subtractItem:**
- Type of parameter for subtractItem

- Item not exists

- Item not available

**Criteria for addQtyToItem and subtractQtyToItem methods:**

- Couple of types of parameters (in oreder)

- Qunatity of item (availability attribute)

- Item not Exists

<br />

**Predicates for all methods:**
