Question Description

Introduction

You have been assigned responsibility for testing a new feature of an Amazing Calculator. This new feature multiplies two numbers together and can either be executed in process or in the cloud. The CloudService used is an off-the-shelf product and is not required to be functionally tested in isolation.

public class AmazingCalculator

{

public int multiplyMe(int a, int b, bool cloudBasedCalc)

{

var retVal = 0;

if (a == 0 || b == 0)

{

return retVal;

}

if (cloudBasedCalc)

{

return multiplyInTheCloud(a, b);

}

if (a == 1)

{

return b;

}

else if (b == 1)

{

return a;

}

for (int count = 0; count < a; count++)

{

retVal = retVal + b;

}

return retVal;

}

// Multiplies two numbers using a remote service private int multiplyInTheCloud(int a, int b)

{

CloudService cloudService = new CloudService();

int retVal = cloudService.RunCloudBasedMultiplication(a, b); return retVal;

}

Exercise

1.Rewrite the class and method interfaces and add additional code to make the whole class 100% branch coverage capable.
