Chapter 5.4, Problem 19STE

Program Plan Intro

Testing:

• It denotes an activity to check whether actual results match expected results.
• It guarantees that software system is defect free.
• It involves execution of a software component for evaluating one or more interest properties.
• It identifies errors, gaps or requirements that are omitted related to actual requirements.
• It could be performed manually or using automated tools.
• It can be classified as white or black box testing.
• The manual testing would include testing of software short of any tool.
  • The tester behaves as an end-user.
  • It tests software for identifying any behavior that is unexpected.
  • The different stages include unit, integration, system as well as user acceptance testing.
• The automation testing uses software to test product.
  • It includes automation for a manual process.
  • The test scenarios are been re-run that are been performed manually.
  • It is used for testing application from performance, load in addition to stress view point.

Driver program:

• The driver program contains the main function of program.
• It is responsible for launching operations in a program.
• It is responsible for converting user program into physical execution unit termed as task.
• Each function must be designed, tested and coded as a discrete unit from rest of program.
• It denotes a testing program for the functions or statement that is been written in code.
• It tests the functionality usually for debugging and code verification.

Given code:

//Define method introduction()

void introduction()

{

//Use namespace

using namespace std;

//Display message

cout << "This program determines the retail price for\n"

<< "an item at a Quick-Shop supermarket store.\n";

}

Explanation:

• The “introduction()” method denotes a “void” method that returns nothing.
• It displays a message regarding the processing of the program.
