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.
