Software Engineering Principles

Instructions:

• Answer 50 questions in 15 minutes.
• If you are not ready to take this test, you can study here.
• Match each statement with the correct term.
• Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. What is testing and verification?
A testing technique whereby the tester tries to execute all possible paths in a program or function.
Also called robustness. The ability of a program to recover following an error; the ability of a program to continue to operate within its environment.
Detecting and fixing errors and demonstrating the correctness of the program.
C++ classes promote information hiding. You can declare private functions and private variables that don't need to be accessable to use the class.


2. What is deskchecking?
The process of executing a program with data sets designed to discover errors.
A combination of branches that might be traversed when a program or function is executed.
To take an object and move it from a general perspective to a precise level of detail. Variations of stepwise refinement include: top- down - bottom- up - functional decomposition - and even 'round- trip gestalt design.'

Also called white- box testing. Testing a program or function based on covering all the statements - branches - or paths of code.
Also called clear- box testing. Testing a program or function based on covering all the statements - branches - or paths of code.
