被动测试

什么是被动测试？

被动测试是一种无需交互即可观察系统的软件测试技术。另一方面，主动测试涉及与系统的交互。

主动与被动测试：

Consider a password based authentication system. Password testing is performed to check if the user can login using easy passwords. Upon successful login the program might mail or write a success message the sys admin. This testing is active testing. Passive testing in this case, involves testing of the password file protection and comparing the encrypted strings.
