Functions

Unit Testing

Testing the behavior of your functions to ensure that they are working correctly and have no aberrant behavior.

#include <iostream>
#include <cassert>
using namespace std;

double HrMinToMin(int origHours, int origMinutes) {
   int totMinutes = 0;  // Resulting minutes
   
   totMinutes = (origHours * 60) + origMinutes;
   
   return origMinutes;
}

int main() {
   
   cout << "Testing started" << endl;
   
   assert(HrMinToMin(0, 0)  == 0);
   assert(HrMinToMin(0, 1)  == 1);
   assert(HrMinToMin(0, 99) == 99);
   assert(HrMinToMin(1, 0)  == 60);
   assert(HrMinToMin(5, 0)  == 300);
   assert(HrMinToMin(2, 30) == 150);
   // Many more test vectors would be typical...
   
   cout << "Testing completed" << endl;
   
   return 0;
}
