Q1) (50 points) Assume that you are given the task of developing a
testing strategy and an
associated
test plan for a
new EMU registration program for
graduate and undergraduate students. Assume the program is being developed by EMU Computer Center employees, and research assistants of the Computer Engineering department,
a) How will you develop a testing strategy for this program? What kind of a strategy is better suited for this program? Briefly explain the structure of your testing strategy.
b) Based on your testing strategy, and assuming that all individual modules are already tested, explain what type of black box tests you will run on this new registration program.
c) After you are finished with your testing, can you be sure that the program is free of errors? Explain.
Q2) (20 points) Given the following flow-graph representing a short program:
a) Find the cyclomatic complexity of this flow-graph.
b) Find a basis set of linearly independent paths for it.
c) Develop
tests cases by listing nodes in visiting order, (like 1-2-4-6-…) which will exercise full coverage for this graph. (So, test cases will force the execution of each linearly independent path in the basis set.)
Q3) (30 points) In a program written by other people, users are supposed to enter the current date in a field:
DD/MM/YYYY
You are given the task of testing whether this input operation works correctly, using a
domain testing approach, but you have
limited time. Do an equivalence class analysis on day, month and year fields and
explain the tests that you would run.
a) First assume non-integer values are not allowed for these fields.
b) Then, assume non-integer values may also be entered.

Q1) (40points) Assume that you are given the task of developing a
testing strategy and an associated
test plan for a
web-based
course grade assignment program for EMU undergraduate students. Assume the program is already developed by EMU Computer Center employees, and you are
not
given the
source code.
The program works as follows: Academic staff members (lecturers or assistants) first enter their code for authorization. Then they select a course which is offered in the current semester. The list of students enrolled to the course appears on the screen and for each student, total scores (out of 100) for all course activities (exam, attendance, homework, or project) is entered. The program then uses defined grade ranges to assign letter grades to students (for example, total score < 50 means the student gets F, total score > 90 means he/she gets A, etc.). Finally, the list of assigned letter grades is displayed for a final check, and upon approval of the academic staff member, it is saved in the Registrar's Office database. The user then logs out of the system.
a) What kind of a testing strategy is better suited for this program? Briefly explain the strategy you propose, stating your reasoning clearly.
b) Based on your testing strategy decision, state which individual tests you will run on this grade assignment program. Explain each test giving an example.
Q2) (30 points) Assume that you are developing a new sorting program which takes a one dimensional non-negative integer array of a maximum size=100, then sorts it in ascending (increasing no.) order using the quick-sort algorithm, and then prints the input array and the sorted array. How would you test this program? Explain your approach clearly.
Q3) (30 points) Assume a large company with more than 1,000 employees already has an employee records keeping and wage computation program which is working fine, and the source code is available. The company has bought another company and 800 more employees are going to join the payment system. However, the new employees will be paid on a different scale (lees TL's per hour). You are given the task of modifying the employee program and testing it. Explain what type of testing strategy you would apply for this case. Then, discuss the tests you would run.

Q1) (50 points) Consider an online
reservation and ticketing system for a bus company that runs busses between Gazimagosa-Lefkosa and Gazimagosa-Girne.
The program is developed by programmers of some other software company and you are given the
Source Code, User's Manual and the Requirements Document for this software system.
The system is an online system, which serves passenger requests on the Web. The passenger can see the time schedule of busses, and he/she can select a certain bus and check whether there are empty seats or not. If there are empty seats, the passenger can either make a reservation, or buy a ticket for that bus. Reservations are kept until 6 hours before the departure of the bus. Payments are made by credit card, through the online banking system of Bank-XXX.
You are the test engineer of an independent testing company, and you are given the task of developing a
testing strategy and an
associated
test plan for this software system. Explain how you would do these, giving details about the testing strategy and discussing the test plan briefly.
Q2) (20 points) Given the following flow-graph representing a short program:
a) Find the cyclomatic complexity of this flow-graph.
b) Find a basis set of linearly independent paths for it.
c) Develop
tests cases by listing nodes in visiting order, (like 1-2-4-6-…) which will exercise full coverage for this graph. (So, test cases will force the execution of each linearly independent path in the basis set.)
Q3) (30 points) Giving examples when necessary, discuss:
a) The difference between
boundary value testing and
robustness testing.
b) The difference between
robustness testing and
worst-case testing.

Q1) (50 points) Assume that you are given the task of developing a testing strategy and an associated test plan for a hospital rendezvous management system for a hospital in Gazimagosa. Assume the program is already developed by a software company, and you are given the source code, user's manual and the requirements document.
The brief description of the system is as follows: Patients make reservation over the Internet. Reservations can be made for 1-7 days from the current day. The patient first enters the web site of the hospital, clicks reservations, then, a menu will show up, which will have a calendar of the coming 7 days. After the patient selects the date, a second menu will appear showing specialty types and rendezvous slots available on the chosen day, on an hourly basis. The patient then selects the specialty type for his/her rendezvous. If there is availability at that period, the system asks for patient information (name, citizen id number, address, phone no, email, etc.) and records the rendezvous for that person. An email and an SMS message are sent to the patient with the rendezvous information. The user then logs out of the system.
a) What kind of a testing strategy is better suited for this program? Briefly explain the strategy you propose, stating your reasoning clearly.
b) Based on your testing strategy decision, state at least five individual tests you will run on this program. Explain each test giving a solid example.
Q2) (25 points) Name TWO tools that you used for testing in your term project.

Q1) (50 points) Assume that you are given the task of developing a testing strategy and an associated test plan for a web-based course grade assignment program for graduate students of EMU. Assume the program is already developed by a private company, and you are given the source code, user's manual and the requirements document.
The program works as follows: Lecturers first enter their code for authorization. Then they select a graduate course which is offered in the current semester. The list of students enrolled to the course appears on the screen and for each student, total scores (out of 100) for all course activities (exam, attendance, homework, or project) is entered. The program then uses defined grade ranges (A, A-, B+, ..,D-, F) to assign letter grades to students (for example, total score < 50 means the student gets F, total score > 90 means he/she gets A, etc.). Finally, the list of students with assigned letter grades is displayed for a final check. Upon the approval of the academic staff member, it is saved in the Registrar's Office database. The user then logs out of the system.
a) What kind of a testing strategy is better suited for this program? Briefly explain the strategy you propose, stating your reasoning clearly.
b) Based on your testing strategy decision, state at least five individual tests you will run on this grade assignment program. Explain each test giving an example.
Q2) (25 points) Consider the following graph G1:
- List all paths that start from initial nodes and end in final nodes.
- Find the reachability set of each node of G1.
- Find all simple paths of G1.
- Find all prime paths of G1.
(Hint: a path from node i to node j is a prime path if it is a simple path and it does not appear as a proper sub-path of any other simple path.)
Q3) (25 points) Compare the Robustness Testing, Worst-case Testing and Robust Worst-case Testing approaches. What are their differences? What are their similarities? Give illustrative examples using a function f(x1, x2) of two variables.
