In order to properly test the Inventory menu it will be required to test basic functions such as adding/modifying/searching. Since all these require user input than that is where most tests will be concentrated. We will also be testing the Security access so each function is secure.

1. User1 will not have change access in the inventory window
   INPUT
   • The user attempts to change one of the fields in the grid that is not 'read-only' to another valid value
   Expected Result
   • The user selects that field in the window
   • The user makes changes to it
   • The user hits enter to attempt to access another field
   • Error message will display saying his access does not allow modifications
   • The field that was changed will restore the original value

2. User2 will have change access in the inventory window
   INPUT
   • The user attempts to change one of the fields in the grid that is 'read-only'
   Expected Result
   • The user selects a 'read-only' field in the window
   • Nothing happens and he will not be allowed to change it

3. User2 will have change access in the inventory window
   INPUT
   • The user attempts to change one of the fields in the grid that is not 'read-only' to another valid value
   Expected Result
   • The user selects a field in the window
   • The user makes changes to it
   • The user hits enter to attempt to access another field
   • The field is changed on the database and proccessing continues

4. User2 will have change access in the inventory window
   INPUT
   • The user attempts to change one of the fields in the grid that is not 'read-only' to another invalid value
   Expected Result

   • The user makes changes to it
