---Easy to use

---Quick and easy cut

Disadvantages of the false assumption method:

---Difficult to know test coverage

---A large number of unknown areas may be lost

---subjective and difficult to replicate

Usage:

1. Use other methods to design test cases first;

2. Use error inference to supplement use cases.

This method is generally only to a certain level can be, primary we still learn it!!!
