        3. You are testing a form that verifies the correctness of the length of the password given as input. The form accepts a password with the correct length and rejects a password that is too short or too long. The password length is correct if it has between 6 and 12 characters inclusive. Otherwise, it is considered incorrect.

At first, the form is empty (password length = 0). You apply boundary value analysis to the “password length” variable.

Your set of test cases achieves 100% 2-value boundary value coverage. The team decided that due to the high risk of this component, test cases should be added to ensure 100% 3-value boundary value coverage.

Which additional password lengths should be tested to achieve this?
