As an important white-box test technology

Basis Path Test could detect more program errors than others. One general method is McCabe. With McCabe method

an executable basis path collection is exported to design test cases through analyzing program structure and loop complexity. But it is difficult to manipulate and easy to make mistakes

which affect the application in Basis Path Test. Aiming at the problem

McCabe method is im- proved in this paper

and the improved method is in contrast with the primary one....
