$(9$ Points$)$ List three data gathering protocols for usability testing.

$(9$ Points$)$ What is the difference between extreme unit testing with regular unit

testing?

$(10$ Points$)$ Suppose that you are performing usability testing and you would like to

decide on the number of testers. If each user can find $10$ percent of the errors,

calculate the least number of testers you would require for finding $90$ percent of the

errors?

$(10$ Points$)$ What are the testing challenges of an internet$-$based application with

respect to a standalone application?

$(10$ Points$)$ What are the pros and cons of testing a mobile application on an emulator

with respect to the real device?

$(12$ Points$)$ Describe debugging by induction and list the procedure for this approach.

$(40$ Points$)$ Suppose that you are writing a program for calculating the final grades of

students using tabular data. In the data table, the first column is student id$,$ second is

midterm grade, and third is quiz grade.

Before you calculate the overall grade, you need to calculate the centered grade for

each individual exam. To calculate the centered grade for each exam, you would need

to calculate the average of that exam $($or quiz$)$ individually, then subtract the

calculated average from each student's grade for that exam and add $60$ to the outcome.

Lastly, you need to weigh the exam with its respective grade $(30\%$ for midterm, $30\%$

for quiz and $40\%$ for the final$)$ and add them up to calculate the overall grade.

Suppose that you read the data from a comma separated values $(.$csv$)$ file and write

your output to another $(.$csv$)$ file.

a$.(10$ Points$)$ For this program, draw a diagram showing the program structure and

individual modules that you would develop.

b$.(10$ Points$)$ Describe the error classes that you would use for each module of this

program.

c$.(20$ Points$)$ For each module, describe the test cases you would use considering

that you are using extreme programming paradigm.
