Ecco un post molto interessante sull'uso del Code Coverage in un caso reale, applicato alle librerie e al compilatore Visual C++. Viene discusso il metodo scelto (cc al 70%), come lo si è realizzato e i risultati ottenuti. Veramente istruttivo:
Our code coverage goal was set to 70% block coverage. You may ask, why not higher, or even 100%? This goal was set after carefully considering the variety of ways in which there might be dead or extremely difficult to hit code in binary. Here are just a few of the situations that would make getting higher code coverage hard:
