This means you may consult your notes, textbooks, andother resources, including calculators, as you see fit. You must submit before the deadline. Allow some spare time for technical submission issues. This assessment is designed to take 2 hours to complete (maybe a little longer to account fortyping speed). The deadline has been set to give you a longer window than necessary to allowyou time to deal with technical issues, provide some flexibility of starting times, and to helpstudents with disability access plans that require rest breaks and extra time. It is suggested that you use Microsoft Word (or any other editor of your choice) to type youranswers, then save as PDF when you are ready to submit. All submitted text must be wordprocessed,but you may include images (or photos of hand drawn images) as part of thedocument. This is an Individual assessment. Under no circumstances are you to discuss any aspect ofthis assessment with anyone; nor are you allowed to share this document, ideas or solutionswith others using email, social media, instant messaging, websites, or any other means. Yourattempts at these questions must be entirely your own work. Those found to have collaboratedwith others will Receive a mark of 0.Special InstructionsAnswer all questions.CS-135留学生作业写作、辅导Software课程作业Submission Instructions Please submit a single PDF file named as your student number (e.g. 123456.pdf) via thesubmission link located on the module page in Blackboard/Canvas.By submitting, electronically and/or hardcopy, you state that you fully understand and are complyingwith the Universitys policy on Academic Integrity and Academic Misconduct.CS-135: Page 1 of 10Question 1:Complete the following sentences:1.

Consider the Computational Problem AlteredProduct:AlteredSum:Input: integers 20 x 20 and 10 y 10Output: integer x + y + 4Give a test Suite for Robustness Testing.[5 marks]2. Consider the following computational problem:carInsuranceRenewal:Input: integers 0 Age 100, 0 C laims 10Output: integer Increase,booleans Warning, Cancelwhere the values for Increase, Warning, and Cancel are computed according to the followingpolicy: If the person is 25 or younger and they have zero claims they will receive a GBP 50 increasein their insurance premium. If the person is 26 or older and they have zero claims they will receive a GBP 25 increase intheir insurance premium. If the person has one claim and they are 25 or younger, they will receive a GBP 100 increase and a warning letter. 26 or older, they will receive a GBP 50 increase. If the person has 2-4 claims, they get a warning letter, and if they are: 25 or younger, they will receive a GBP 400 increase. 26 or older, they will receive a GBP 200 increase. If the person has more than 5 claims, their policy is canceled (and no increase to premium).(a) Define Partitions for the input domains of the carInsuranceRenewal problem.(b) Give a minimal test suite for weak-normal equivalence class testing. Note that the output isa triple of values, namely a value for increase a value for warning a value for cancelConsider a test case encoding that a person of age 6 has collected 4 claims and thereforeought to receive a GBP 400 increase and a warning letter, but have their policy continue.In a table form, this test case could be represented as:Test-Name Age Claims Expected outputIncrease Warning CancelT1 7 4 400 true falseCS-135: Page 3 of 10(c) Combine weak-normal equivalence class testing and boundary value analysis testing to a newtest approach, where each set in the original partition is divided into three sets (if possible) Min set – consisting of the minimum value Max set – consisting of the maximum value Norm set – consisting of all other values and the single fault assumption is applied.To this end,i. Define the new partitions for the problem.ii. Give a minimal test suite for such combination of methods.[1.5 + 1 + (3.5 + 4) = 10 marks]CS-135: Page 4 of 10Question 3: Whitebox testing1. ConsiderThe Computational Problem Sort:SortInput: array A of integersOutput: a sorted version of Aand a Java program solving this problem:source: httpss://www.sanfoundry.com/java-program-implement-selection-sort/You can write arrays as [1, 2, 3] or [] for the empty array.(a) Give a Path in the program graph of selection sort that needs to be covered to ensure C0coverage.(b) Give a minimal test suite for C0.(c) Does any minimal test Suite of selection sort for C0 also cover for Cp?(d) Give a minimal test suite for Ci(3).(e) Does your minimal testsuite for Ci(2) execute all loops for the required number of times?[1 + 1 + 1 + 2 + 1 = 6 marks]2. A coverage Criterion A is different from a criterion B, if there exist a program P such that coveringfor A requires a different set of paths to be covered in the program graph of P than for B.(a) Write a Java program and explain why it demonstrates that C0 and Cp are different testingcriteria.(b) Write a Java program and explain why it demonstrates that Cp and Ci(1) are different testingcriteria.[4.5 + 4.5 = 9 marks]End of PaperCS-135: Page 5 of 10如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
