Question

Write a unit test for addInventory(). Call redSweater.addInventory() with parameter sweaterShipment. Print the shown error if the subsequent quantity is incorrect. Sample output for failed unit test given initial quantity is 10 and sweaterShipment is 50:
Beginning tests.
UNIT TEST FAILED: addInventory()
Tests complete.
Note: UNIT TEST FAILED is preceded by 3 spaces.

#include
using namespace std;

class InventoryTag {
public:
InventoryTag();
int getQuantityRemaining() const;
void addInventory(int numItems);

private:
int quantityRemaining;
};

InventoryTag::InventoryTag() {
quantityRemaining = 0;
}

int InventoryTag::getQuantityRemaining() const {
return quantityRemaining;
}

void InventoryTag::addInventory(int numItems) {
if (numItems > 10) {
quantityRemaining = quantityRemaining + numItems;
}
}

int main() {
InventoryTag redSweater;
int sweaterShipment = 0;
int sweaterInventoryBefore = 0;

sweaterInventoryBefore = redSweater.getQuantityRemaining();
sweaterShipment = 25;

cout << "Beginning tests." << endl;

// FIXME add unit test for addInventory

/* Your solution goes here */

cout << "Tests complete." << endl;

return 0;
}

Answer 1

Answer:

kindly check explainations for code

Explanation:

Header files

#include <iostream>

using namespace std;

// define class InventoryTag

class InventoryTag

{

public:

// constructor

InventoryTag();

// declare functions

int getQuantityRemaining() const;

void addInventory(int numItems);

private:

// declare a variable

int quantityRemaining;

};

InventoryTag::InventoryTag()

{

quantityRemaining = 0;

}

// function definition

int InventoryTag::getQuantityRemaining() const

{

return quantityRemaining;

}

// function definition

void InventoryTag::addInventory(int numItems)

{

if (numItems > 10)

{

quantityRemaining = quantityRemaining + numItems;

}

}

// main function

int main()

{

// create an object for class InventoryTag

InventoryTag redSweater;

// Declare variables

int sweaterShipment = 0;

int sweaterInventoryBefore = 0;

// Call getQuantityRemaining()function

sweaterInventoryBefore =

redSweater.getQuantityRemaining();

// Assign a value to variable

sweaterShipment =25;

cout << "Beginning tests." << endl;

// FIXME add unit test for addInventory

/* Your solution goes here */

// Call addInventory() function

redSweater.addInventory(sweaterShipment);

// Check whether the result is expected result

// or not

if (redSweater.getQuantityRemaining() !=

sweaterShipment + sweaterInventoryBefore)

{

// Print error message

cout << " UNIT TEST FAILED: addInventory()"

<< endl;

}

cout << "Tests complete." << endl;

system("pause");

return 0;

}

Answer 2

Answer:

redSweater.addInventory(sweaterShipment);

if (redSweater.getQuantityRemaining() != sweaterShipment + sweaterInventoryBefore) {

System.out.println("   UNIT TEST FAILED: addInventory()");

}

Explanation:

The if statement sets a condition for the unit test. If the condition isn't met then it prints the unit failed statement. Also, the answer above is kinda right but has lots of extra stuff in the code. Remember to have 3 spaces before the unit failed statement, 1 test will pass but the last one won't.
