Los casos de prueba son una parte extremadamente importante de cualquier “Proceso de prueba de software/proyecto”. Por lo tanto, este conjunto será muy importante para todos los aspirantes a desarrolladores de software. Los siguientes son los programas para generar casos de prueba.

Funciones de biblioteca utilizadas
- Función rand() –
-> Generar números aleatorios del rango 0 a RAND_MAX (32767)
-> Definido en el encabezado <stdlib.h>/<cstdlib>
-> Si queremos asignar un número aleatorio en el rango – m a n [n >= m] a una variable var, luego use-
var = m + ( rand() % ( n – m + 1 ) );
-> Esta función es una función de tiempo de ejecución. Entonces, los valores: n, m deben declararse antes de compilar, al igual que tenemos que declarar el tamaño de la array antes de compilar.
-> Llame a esta función cada vez que desee generar un número aleatorio - función time()
-> Devuelve el número de segundos desde [00:00:00 UTC, 1 de enero de 1970]
-> Definido en el encabezado <time.h> - srand (semilla)
-> Genera un número aleatorio de acuerdo con la semilla que se le pasó.
-> Si esta función no se usa y usamos la función rand(), entonces cada vez que ejecutamos el programa se generan los mismos números aleatorios.
-> Para superar la limitación anterior, pasamos el tiempo (NULL) como semilla. Por lo tanto, srand(time(NULL)) se utiliza para generar valores aleatorios cada vez que se ejecuta el programa.
-> Utilice siempre esto al comienzo del programa, es decir, justo después de int main() {
-> No es necesario llamar a esta función cada vez que genera un número aleatorio
-> Definido en el encabezado <stdlib.h>/<cstdlib> - freopen(“output.txt”, “w”, stdout)
-> Escribe (es por eso que pasamos “w” como segundo argumento) todos los datos al archivo output.txt (El archivo debe estar en el mismo archivo que el programa es en).
-> Se utiliza para redirigir stdout a un archivo.
-> Si el archivo output.txt no se crea antes, se crea en el mismo archivo en el que se encuentra el programa. - fclose(stdout)
-> Cierra el archivo de flujo de salida estándar para evitar fugas.
-> Utilice siempre esto al final del programa, es decir, justo antes de return(0) en la función int main().
