Question

The Brookings Nut house sells peanuts for $3 per pound and cashews for $5 per pound with a 10% discount for orders over $20. Since this is a special offering there is a limit of 20 lb for each kind of nut for each customer. A unit has been programmed to compute the price of an order given the weights of peanuts and cashews. The unit is required to print an invalid data message for weights that are negative or over 20 lb for each kind of nut.

Write a complete unit test plan, that including derivation of test cases, and test cases

Answer 1

scanf("%d%d",pea,cas);

if(pea<20)

{

w1=pea*3;

if(w1>20){

w1=(w1*90)/100

}

}

else{

printf("peanut weight more than 20 pounds")

}

if(cas<20)

{

w2=cas*5;

if(w2>20){

w2=(w2*90)/100

}

}

else{

printf("cashew weight more than 20 pounds")

}
