Software Testing: Discuss the principles of mutation testing as an advanced software testing technique. Explain how mutation testing works, its strengths in revealing weak spots in test suites, and the challenges in implementing it effectively. Provide examples of scenarios where mutation testing is particularly beneficial.

Assume that you must take a computer-programming language course next semester. How would you decide which language would be best for you to study? Do you think that a professional programmer needs to know more than one programming language? Why or why not?

An organization has selected and is now implementing a software package. Identify three key factors that will determine the cost and time required for implementation.

_______ is a form of testing that involves linking all of the individual components together and testing them as a group to uncover any defects between individual components. a. Unit testing b. System testing c. Integration testing d. Volume testing

The ______ approach is a structured, interactive, iterative decision-making method that relies on input from a panel of experts.

(Data processing) a. A national medical testing laboratory wants a new computer system to analyze its test results. The system must be capable of processing each day’s results as well as retrieving and outputting a printed report of all results meeting certain criteria, such as all results for a particular doctor or for hospitals in a certain state. Determine three or four major program units into which this system could be separated. (Hint: One possible program unit is “Prepare Daily Results” to create each day’s reports.) b. Suppose someone enters incorrect data for a test result, and the error is discovered after the system has entered and stored the data. What program unit is needed to correct this problem? Discuss why such a program unit might or might not be required by most systems. c. A program unit has been developed that allows users to change data that has been entered and stored incorrectly. Discuss the need for including an “audit trail” that would allow reconstructing the changes later as well as when they were made and who made them.
