Testing

When you complete the testing section of your project you need to make sure your testing table is specific and attempts to test all possible inputs.

Below are a series of programs and completed testing tables so you can see how you should complete the testing tables.

Example 1 - Email Address Validation

This program gets the user to enter an email address and it will decide if it is valid or not. The email address must follow the following format:

Program code:

import re
password = input("Enter an email address: ")
while len(password)==0:
    password = input("Enter an email address: ")
pattern = "^[A-Za-z0-9]+\@[A-Za-z0-9]+\.[A-Za-z0-9]+$"
passwordMatch = re.match(pattern, password)
if passwordMatch:
    print("VALID")
else:
    print("INVALID")

Example 2 - Grade Calculator

This program gets the user to enter a test score between 0 and 100. It will then say the grade and how many marks they are off the next grade. The grade boundaries are:

Program code:

valid=False
while valid==False:
    score = input("Enter a score between 0 and 100: ")
    if score.isdigit()==False:
        valid=False
    else:
        valid=True
        if int(score)<0 or int(score)>100:
            valid=False
score=int(score)
if score >=70:
    marksoff = 100-score
    print("That test score is a grade A, you were "+str(marksoff)+" marks off full marks")
elif score>=60:
    marksoff = 70-score
    print("That test score is a grade B, you were "+str(marksoff)+" marks off an A")
elif score>=50:
    marksoff = 60-score
    print("That test score is a grade C, you were "+str(marksoff)+" marks off a B")
elif score>=40:
    marksoff = 50-score
    print("That test score is a grade D, you were "+str(marksoff)+" marks of a C")
else:
    marksoff=40-score
    print("That test score is a grade U, you were "+str(marksoff)+" marks off a D")

Example 3 - Speeding Cars

This program reads a file that contains a list of car registration plates and the speed they were captured at going through a speed camera. The user will enter the speed limit and it will display which of the cars in the file were speeding. Part of the file cars.csv is shown below:

Testing19

Program code:

speed = input("Enter the speed limit (mph) ")
file = open("cars.csv","r")
speeding = False
for line in file:
    cars = line.split(",")
    if float(cars[1])>float(speed):
        speeding = True
        print(cars[0] + " " + cars[1])
file.close()
if speeding == False:
    print("There were no cars that broke the speed limit of " + speed + "mph")

Example 4 - Order Program

This program reads a file that contains a list of products and their prices sold in a shop. The user enters a GTIN code (barcode) and how many the customer wants. It then calculates the total cost of each item and a grand total and creates a receipt.

Program code:

anotherItem=True
receipt=""
totalcost=0
while anotherItem is True:
    gtin = input("Enter a GTIN8 Number: ")
    quantity = input("Enter a quantity: ")
    file=open("Products1.csv","r")
    itemFound=False
    for line in file:
        product=line.split(",")
        if product[0]==gtin:
            price=float(product[2])
            itemFound=True
            itemTotal=round(price*int(quantity),2)
            receipt=receipt+"\n"+product[0]+" "+product[1]+" "+quantity+" "\
                     +"£{:.2f}".format(price)+" "+"£{:.2f}".format(itemTotal)
            print("Current Order")
            print(receipt)
            totalcost=totalcost+itemTotal
    file.close()
    if itemFound==False:
        receipt=receipt+"\n"+gtin+" product not found"
        print(receipt)
    continueOrder=input("Order another item (y/n)?")
    if continueOrder=="y":
        anotherItem=True
    else:
        anotherItem=False
print("Order complete")
receipt=receipt+"\n"+"Total cost of order £{:.2f}".format(totalcost)
print(receipt)

Example 5 - Reorder Program

This program reads a file that contains a list of products and how many there are in stock. If the number in stock is low, it works out how many need to be reordered and then creates a new file of the products that need to be reordered as well as how many.

Program code:

print("List of products that are below the reorder level and need to be reordered:")
itemsforreorder=0
file=open("catalogue - T3.csv","r")
for line in file:
    product=line.split(",")
    if int(product[3])<int(product[4]):
        reorderamount=int(product[5])-int(product[3])
        print(product[0]+" "+product[1]+" "+str(reorderamount))
        reorderfile=open("reorderlist.csv","a")
        reorderfile.write(product[0]+","+product[1]+","+str(reorderamount)+"\n")
        reorderfile.close()
        itemsforreorder=itemsforreorder+1
file.close()
if itemsforreorder>0:
    print("Reorder file created")
else:
    print("No products need reordering")

Example 6 - Updating Staff Information

This program updates the number of years a member of staff has been working at the school. When the program runs the user enters their email address, when it finds the person it asks them to enter their number of years teaching. It will then update the file if the person exists in the file.

Program code:

import os, sys
updateanother = "Y"
while updateanother == "Y":
    email = input("Enter the email address you are looking for:")
    file = open("staff.csv","r")
    alreadyexists=False
    for line in file:
        staff = line.split(",")
        writefile = open("staffupdated.csv","a")
        if staff[2] == email:
            alreadyexists=True
            print("Current Details:\nStaff name: " + staff[0] + " " + staff[1] + "\nEmail Address: " + staff[2] + "\nYears Teaching: " + staff[3])
            yearsteaching =input("Enter their new number of years teaching: " )
            writefile.write(staff[0] + "," + staff[1] + "," + staff[2] + "," + yearsteaching+"\n")
        else:
            writefile.write(staff[0] + "," + staff[1] + "," + staff[2] + "," + staff[3])
        writefile.close()
    file.close()
    os.remove("staff.csv")
    os.rename("staffupdated.csv","staff.csv")
    if alreadyexists==False:
        print("That staff member's email cannot be found in the file, no changes made")
    else:
        print("Details updated")
    updateanother = input("Would you like to update another staff member? Y/N ")
