Transport Application – Christmas Parcel Delivery Calculator

Test Case

1.Algorithm:

Step 1: Initialize the variable to store the data

Step 2: Display the Welcome message

Step 3: Display the Menu

Step 4: Get the menu option from the user

Step 5: If the User Selects Setup Cost Per KM option perform step 6 and 7 else move to Step 10

Step 6: Get the costs per km for a package to be sent for 100KM or less distance from the User

Step 7: Get the costs per km for a package to be sent for over 100KM distance from the User

Step 8: Display the details entered by the user

Step 9: Go to Step 3

Step 10: If the User Selects Enter Parcel option perform step 11 to 17 else move to Step 18

Step 11: Get the receiver name of the package from the User

Step 12: Get the weight of the package from the User

Step 13: Get whether the insurance is required for the package from the User

Step 14: Get the number of KMs the package wants to travel from the User

Step 15: Display the details entered by the user

Step 16: Compute the delivery date of the package

Step 17: Go to Step 3

Step 17: If the User Selects Display Parcel Delivery Costs option perform step 18 to 23 else move to Step 24

Step 18: Compute the transportation cost by multiplying the distance and its corresponding cost

Step 19: Determine the insurance cost if the insurance is required for the package

Step 20: Compute the total cost i.e. transportation cost + insurance cost

Step 21: Display the cost details

Step 22: Display the delivery date of the package

Step 23: Go to Step 3

Step 24: If the user select the Exit System option perform step 25 else go to step 27

Step 25: Display the Exit message to the user

Step 26: Terminate the program execution

Step 27: If the user enters none of the option; Display the message of invalid choice and Go to Step 3

3.Testing Base Requirement:

Test Case	Expected Result	Actual Result
The user selects the menu option: Setup Cost Per KM	The user is prompted to enter the travel cost (per KM) for a package sent under 100KM and sent over 100KM	Enter how much it costs per km for a package to be sent 100KM or less: $ 0.59 Enter how much it costs per km for a package to be sent over 100KM: $ 0.86
The user selects the menu option: Enter Parcel	The user is prompted to enter the receivers name, the weight of the parcel, if they want insurance and how far the parcel is to be sent	Enter receivers name: Greg Enter weight of parcel: 100 Do you want insurance (Y or N)? Y How far do you want to send the parcel (km)? 512
The user selects the menu option: Display Parcel Delivery Costs	Displays calculation of the transportation, insurance and total costs	Transportation Costs: 440.32 Insurance Costs: 53.0 Total Costs: 493.32
