+Il branch coverage di un insieme di test cases è la percentuale di branch del programma che sono attraversati da almeno un test case.
+
+Si consideri il seguente programma C:
+
+-----------
+
+#include <stdio.h>
+
+#include <stdlib.h>
+
+#include <assert.h>
+
+#define N  4    /* number of test cases */
+
+
+int f(int x1, int x2)
+
+{
+  if (x1 + x2 <= 2)
+
+  return (1);
+
+  else return (2);		    
+
+}
+
+
+int main() {    int  i, y;   int x1[N], x2[N];
+
+  // define test cases
+
+    x1[0] = 3; x2[0] = -2;    x1[1] = 4; x2[1] = -3;    x1[2] = 7; x2[2] = -4;    x1[3] = 8; x2[3] = -5; 
+
+    // testing
+
+  for (i = 0; i < N; i++)  {
+
+      y = f(x1[i], x2[i]);       // function under testing
+
+      assert(y ==(x1[i], x2[i] <= 2) ? 1 : 2);   // oracle
+
+    }
+
+   printf("All %d test cases passed\n", N);
+
+    return (0);   
+
+}
+-----------
+
+Il programma main() sopra realizza il nostro testing per la funzione f1(). I test cases sono i valori in x1[i] ed x2[i].
+
+Quale delle seguenti è la branch coverage conseguita?
