SWE 3643 Assignment 3 1) This assignment comes in 3 parts (see below for Parts A,B & C); total is ---50 points ---- (form a team of approximately ~4 partners by June 25) 2) 10% late penalty--- but after 6/27/2015 class period the score will be 0 Consider the following problem: (Read the whole assignment) Write a program that will read two inputs, income (inc) and number of dependents (dep). Based on the income, the program will calculate the tax-amount according to the following table. income 0 < inc ≤ 20000 20000 < inc ≤ 30000 30000 < inc ≤ 40000 40000 < inc ≤ 50000 50000 < inc ≤ 90000 90000 < inc Tax-amount (% of income) 4% 5% 6% 7% 10 % 13 % Furthermore, if there is any dependent, then the tax-amount is further decreased accordingly. Dependent = 1 10% 2 ≤ dependent ≤ 3 25% Dependents > 3 40% Print out three items: income, # of dependents, and tax amount. (Part A - 15 points) Using the requirements statements above, design and show all your test cases using various techniques learned for Functional or Black-box testing (at least include boundary-value and decision-table techniques). (Part –B – 15 points) Looking a the pseudo code on the next page, design and show all your test cases using various techniques learned for Structural or White-box testing (at least branch coverage, linearly independent paths, and define-use paths techniques). (Part – C – 20 points) Convert the pseudo code to your favorite language code, get it to compile correctly, execute your test cases from part A and B against the code, record all the errors found, and provide a report on your testing results. The report should provide: i) a summary list of your test cases in Part A and test cases in Part B, ii) execution test results (numbers passed and numbers failed – with severity), iii) any fixing or re-test performed, iv) a discussion on the “effectiveness” of your test cases, including how do you know when to stop testing and v) a discussion of your experiences (e.g. what was difficult to design; how much effort did it take to design test cases, execute the test cases and record the material; what was easy and what was not, etc.). (Look at Lecture Notes on Test Planning for hint of Test Result Report.) Also send your report as a pdf file to me. Possible Pseudo –Code (that may contain defects caused by my human errors): start program read ( inc, dep) bracket = 0 if (0 < inc ≤ 20000) bracket = 1 else if ( 20000 < inc ≤ 30000) bracket = 2 else if (30000 < inc ≤ 40000) bracket = 3 else if (40000 < inc ≤ 50000) bracket = 4 else if ( 50000 < inc ≤ 90000) bracket = 5 else bracket = 6 switch (bracket) { case 1: tax = inc * .04 break case 2: tax = inc * .05 break case 3: tax = inc * .06 break case 4: tax = inc * .07 break case 5: tax = inc * .10 break case 6: tax = inc * .13 break default: output (“ something is wrong with the income bracket computation”) } if (dep = 1) tax = tax - (.1 * tax) else if ( 2 ≤ dep ≤ 3 ) tax = tax – (.25* tax) else if ( 3< dep ) tax = tax – (.4 * tax) else tax = tax output ( “income” = inc, “dependent’ = dep, “tax” = tax ) end program
